The Summer Undergraduate Research Fellowship (SURF) Symposium
Solution processed thin film solar cells are attractive alternatives to conventional energy sources due to low waste generation, flexibility in substrate choice, and scalability. The novel semiconductor Cu3AsS4 in the enargite phase has a near ideal band gap of 1.4 eV and has earth abundant constituent elements; yet single-junction solar cells have yielded low efficiencies due to a secondary carbonaceous phase present, among other issues. This carbonaceous phase may be eliminated by exchanging the carbonaceous ligands with molecular metal chalcogenides. To characterize the ligand exchanged particles, UV-Vis-NIR spectroscopy, Raman spectroscopy, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, and …

College of Engineering: Graduate Celebration Programs
- Build a model of spiral nanoantenna and an antenna
array based solar cell collector. - Using Rao-Wilton-Glisson (RWG) basis functions to
simulate the spiral nanoantennas. - We calculate the frequency response of the radiation
gain as the indicator of receiving bandwidth which is a
key factor in conversion efficiency.
