Fully Solution Processed Pedot:Pss And Silver Nanowire Semi-Transparent Electrodes For Thin Film Solar Cells, Bjorn Vaagensmith
Fully Solution Processed Pedot:Pss And Silver Nanowire Semi-Transparent Electrodes For Thin Film Solar Cells, Bjorn Vaagensmith
Electronic Theses and Dissertations
Building integrated photovoltaics (BIPV), such as semitransparent organic solar cells (OSC) for power generating windows, is a promising method for implementing renewable energy under the looming threat of depleting fossil fuels. OSC require a solution processed transparent electrode to be cost effective; but typically employ a nonsolution processed indium tin oxide (ITO) transparent electrode. PEDOT:PSS and silver nanowire transparent electrodes have emerged as a promising alternative to ITO and are solution processed compatible. However, PEDOT:PSS requires a strong acid treatment, which is incompatible with high throughput solution processed fabrication techniques. Silver nanowires suffer from a short lifetime when subject to …

Lead Free Ch3nh3sni3 Perovskite Thin-Film With P-Type Semiconducting Nature And Metal-Like Conductivity, Anastasiia Iefanova
Electronic Theses and Dissertations
CH3NH3SnI3 and CH3NH3PbI3 have become very promising light absorbing materials for photovoltaic devices over the last several years. CH3NH3PbI3 based perovskite solar cells have reached a solar-to-electricity conversion efficiency of ~ 22%. Nevertheless, CH3NH3PbI3 perovskite solar cells contain lead, which has serious consequences for the environment and human health. In this work, the lead was replaced with less toxic tin. Lead free CH3NH3SnI3 perovskite thin film was prepared by two low temperature solution processing methods and characterized using various tools such as Xray Diffraction (XRD) and absorption spectroscopy (UV-VIS). The distinctive p-type semiconducting nature and metal like conductivity of CH3NH3SnI3 …
