Low Temperature Flexible Perovskite Solar Cell With Mesoporous Tio2 Electron Transport Layer In High Humidity Environment, Felipe De La Torre

Theses and Dissertations

Perovskite solar cells are the fastest advancing solar technology to date with efficiencies increasing from 3.9% to more than 21% within a few years. They have emerged as a possible alternative to silicon photovoltaics due to their exceptional photovoltaic performance, light absorbing properties, and low-cost fabrication with methylammonium lead iodide (CH3NH 3PbI3) getting considerable interest in research and development. However, there are still many challenges that must be addressed for perovskite solar cells to replace contemporary solar cells, such as improving their stability, making them nonhazardous, further increasing their efficiency, and developing better techniques for large scale fabrication. In this …

Extension Professionals' Perspectives On Supporting Feedstock Production For Biofuels: Concerns, Challenges, And Opportunities, Patricia A. Townsend, Nora M. Haider, Stanley T. Asah, Kevin W. Zobrist

The Journal of Extension

The development of successful bioenergy programs will depend on informed and prepared Extension professionals who are willing and equipped to provide technical support. A survey of Extension professionals in the Pacific Northwest revealed barriers to program development, including limits on time and knowledge and concerns about economic returns for biofuel crops. Without the promise of market opportunities, Extension professionals may be unwilling to devote requisite resources to bioenergy programs. However, government policies and mandates make the rise of biofuels highly likely. Extension professionals should look to the future and consider blending bioenergy education into existing programs.

Three Essays On Sustainable Development In China: Social, Economic And Environmental Aspects, Ying Chen

Doctoral Dissertations

The first essay focuses on the role of the hukou (i.e. Household Registration System) with full awareness of the economic system it operates under, and the development model it assists. I find that hukou’s main role in the planned economy was to assist socialist industrialization while averting the Lewis development model, a development strategy based on unlimited supply of labors from the rural sector, largely adopted in developing countries. In the market reform period, hukou performed exactly the opposite function, which is to assist the Lewis model based on the unlimited supply of rural surplus labor “released” from the …

Public Views On Renewable Energy In The Rocky Mountain Region Of The United States: Distinct Attitudes, Exposure, And Other Key Predictors Of Wind Energy, Shawn K. Olson-Hazboun, Richard S. Krannich, Peter Robertson

Sociology, Social Work and Anthropology Student Research

Renewable energy is often framed by policymakers and the media as an environmental or ‘green’ issue motivated by global climate change and the need for greenhouse gas reductions. However, some researchers studying social responses to renewables have found that factors other than opinions about climate change may be more influential in determining support for renewables. This study analyzes survey data from a study of five communities in the Rocky Mountain region of the U.S. experiencing wind energy development to examine the relationship between environmental beliefs, climate change opinions, and support for renewable energy. Results show that views on renewable energy …

Soft Energy Paths Revisited: Politics And Practice In Energy Technology Transitions, Chelsea Schelly, Aparajita Banerjee

Department of Social Sciences Publications

This paper argues that current efforts to study and advocate for a change in energy technologies to reduce their climate and other environmental impacts often ignore the political, social, and bodily implications of energy technology choices. Framing renewable energy technologies exclusively in terms of their environmental benefits dismisses important questions about how energy infrastructures can be designed to correspond to democratic forms of socio-politics, forms of social organization that involve independence in terms of meeting energy needs, resilience in terms of adapting to change, participatory decision making and control, equitable distribution of knowledge and efficacy, and just distribution of ownership. …

Persistensi Bahan Bakar Fosil: Analisis Path Dependence Dalam Bauran Konsumsi-Energi Indonesia Periode 1980–2015, Made Harimbawa

Jurnal Kebijakan Ekonomi

Current fossil fuels use has created two major issues: environmental damage from greenhouse gas emissions and energy security. In the recent decades, development in science and technology along with increasing demand for shifting to cleaner and renewable energy sources have not yet changed the proportion of fossil fuel in Indonesia energy-consumption mix. One explanation to this phenomenon is the existence of path dependence that locks Indonesia’s technological systems and institutions into cycles of fossil fuels consumption, which in turn limiting the development of alternative technologies. Analysis using equilibrium dependent model suggests that this is the case: fossil fuels persistence in …

Characterization Of S-Swcnt/Pf-Pd Dispersions And Networks, Tamara N. El-Hayek Ms., Jeffrey Blackburn, Andrew Ferguson, Tammy Pheuphong

STAR Program Research Presentations

Single-Walled Carbon Nanotubes (SWCNTs) are being investigated for their use in a wide variety of renewable energy applications. Their unique physical properties contribute to desirable traits such as a high carrier mobility, strong optical absorption and tunable electronic band gap. Unfortunately, due to variability in certain parameters, SWCNTs are limited in their application. The major drawback is that SWCNTs are variable in size and type and typical synthetic methods are not selective. As a result, selective methods must be developed in order to sort these tubes and extract those which are desirable for a particular application. Though there are several …

Testing Predictions Used To Build An Agrivoltaics Installation On A Small-Scale Educational Model, Katie Kinney, Rebecca Minor, Greg Barron-Gafford

STAR Program Research Presentations

Models are valuable tools for explaining and testing systems. Small-scale models can be especially useful for educational purposes. For models to be useful, they have to accurately depict the larger system that they are describing. A novel man-made system, known as an agrivoltaic structure, is being constructed at Biosphere 2 near Oracle, Arizona. The word agrivoltaic is a combination of agriculture and photovoltaics, or solar farming. My research involved creating a small-scale version of this system for educational purposes. The model of this system tested two predictions: that plants will grow better in the shade of a panel and that …

Oregon Natural Desert Association V. Jewell, Jody D. Lowenstein

Public Land & Resources Law Review

In Oregon Natural Desert Association v. Jewell, the Ninth Circuit invalidated the BLM’s environmental review, finding that the agency based its approval of a wind-energy development on inaccurate scientific analysis. In negating the BLM’s action, the court held that flawed data and indefensible reasoning were discordant with NEPA’s central tenets. Furthermore, the court did not hold the BLM responsible for addressing a distinct environmental issue that was not brought to its attention during the public comment period.

Optimization Of Electricity Generation Schemes In The Java-Bali Grid System With Co2 Reduction Consideration, Farizal Farizal, Wenty Eka Septia, Amar Rachman, Nasruddin Nasruddin, Teuku Meurah Indra Mahlia

Makara Journal of Technology

This research considers the problem of reducing CO2 emissions from the Java-Bali power grid system that consists of a variety of power-generating plants: coal-fired, natural gas, oil, and renewable energy (PV, geothermal, hydroelectric, wind, and landfill gas). The problem is formulated as linear programming and solved using LINGO 10. The model was developed for a nation to meet a specified CO2 emission target. Two carbon dioxide mitigation options are considered in this study, i.e. fuel balancing and fuel switching. In order to reduce the CO2 emissions by 26% in 2021, State Electric Supply Company (PLN) has to generate up to …

Novel Pathways To High-Efficiency Chalcopyrite Photovoltaic Devices: A Spectroscopic Investigation Of Alternative Buffer Layers And Alkali-Treated Absorbers, Michelle Mezher

UNLV Theses, Dissertations, Professional Papers, and Capstones

Within the past few years, breakthroughs in Cu(In,Ga)Se₂ (CIGSe) thin-film photovoltaic device efficiencies (on a laboratory scale) were achieved utilizing alkali-treated (KF) absorbers. Na incorporation in the CIGSe absorber, either diffused from the substrate or deliberately deposited, affects the surface electronic properties of the CIGSe absorber. The role of Na, however, is still not fully understood with some studies suggesting that Na also passivates defects at the grain boundaries. Replacing Na with K offered an efficiency boost resulting in KF treatments becoming the new “hot topic” in the chalcopyrite field, both in terms of understanding how the treatment changes …

Commercial Solar Technology Adoption In The United States: Empirical Evidence On Effects Of State Policies, Eric Koegler

Masters Theses

Growing concerns about greenhouse gas emissions as well as electricity prices have led to more serious efforts by the state and federal government to provide promote renewable energy at affordable costs. I examine the effect of policies and incentives on added commercial solar PV capacity while controlling for pro-environmental preferences, energy prices, geographic controls, and demographic controls. I use county-level data that spans twelve northeastern states and the District of Columbia from 2005 through 2013. I utilize the Tobit estimator to account for a mass point of solar PV capacity at zero kilowatts. The results suggest that loans, performance-based incentives, …

Demand Response And Market Power, Bruce R. Huber

Bruce R Huber

In her article, Bypassing Federalism and the Administrative Law of Negawatts, Sharon Jacobs educates her readers about the concept of demand response, and then describes its propagation in recent years while making the broader argument that the Federal Energy Regulatory Commission (“FERC”) — the federal government’s principal energy regulator — has engaged in a strategy of “bypassing federalism” that may entail more costs than benefits. Professor Jacobs is right to call attention to demand response and to FERC’s approach to matters of jurisdictional doubt. While I share many of her concerns about boundary lines in a federal system, I argue …

Extraterritoriality, Externalities, And Cross-Border Trade: Some Lessons From The United States, The European Union, And The World Trade Organization, Max S. Jansson

Pace Environmental Law Review

In this article, process and production method (PPM) rules are analyzed under three jurisdictions: the United States, the European Union (EU), and the World Trade Organization (WTO. The approach is justified by the fact that their rules on interstate trade reflect very similar basic objectives related to anti-protectionism. Moreover, the regimes, to a large extent, share the same structure of rules on prohibition balanced with rules on justification. All in all, the regimes reveal similar syntax. The comparability of the U.S. Dormant Commerce Clause Doctrine with both WTO law and EU free movement law has been highlighted already in previous …
