In the future many modern buildings may rely on solar windows for energy production. Large buildings often have glass facades which have the potential to convert sunlight to electrical power. The standard photovoltaic materials used today are bulky and not transparent, making them poor candidates for solar windows. Mono and few-layer transition metal dichalcogenides (TMDC’s) are an exciting new material in photovoltaic field. They have high incident light absorbance, good charge carrier mobility, and strong photoluminescence. In addition these thin layers are also quite transparent making them good candidates for transparent applications such as solar windows. There have already been attempts to make solar cells with TMDCs, but the research is so new that there are many avenues that have not yet been studied. Using well established knowledge about thin-film solar cells along with newly emerging research about TMDCs, the main motivation of this thesis is to create a solar cell using TMDC material as an absorber layer. In order to make this type of solar cell I am investigating different transparent contact materials and the charge carrier transfer between mono and few layer TMDCs and these 3D semiconducting materials.
