Modern solar cells are composed of silicon, cadmium tellurium, and copper indium gallium diselenide. While these materials are efficient, elements such as cadmium and indium are rare and expensive. To make this renewable energy source more inexpensive and sustainable, the Liu Optics lab is substituting expensive rare earth metals for more commonly found transition state metals. Work has been done to replace the solar cell layers composed of cadmium and gallium to replace them with glass, silicon, and/or thin films. Common metals such as germanium and tin are investigated and characterized to provide a platform for solar cell components.

ENGS 88 Honors Thesis (AB Students)
This is a feasibility study of Dartmouth's Renewable Energy propositions. This study analyzes the carbon offsets of implementing a 13 MW solar PV system at Oak Hill. This study used the Energy Database to calculate the carbon emissions of the college for 2010 (the baseline year) and 2018. It also projected carbon emissions for the year 2025 assuming the Oak Hill solar PV system is implemented as outlined and the biomass plant is implemented with similar fuel ratios to nearby biomass plant projects. It was found that Dartmouth should sufficiently make its carbon emissions reductions goals for 2025.
