Thin Film Photovoltaics and Radiation Detectors Research Group

The Thin Film PV research group performs research on hybrid organic-inorganic perovskite halides PV materials and devices. Current research materials include the study and the development of methylammonium lead tri-iodide CH3NH3PbI3 perovskites absorbers, spiro-OMeOTAD, P3HT, ZnO, ITO, TiO2, Mo, Ag, Al, and Au. Materials are deposited using different deposition techniques, ranging from spin coating, chemical bath deposition, rf and dc sputtering, and thermal evaporation. Materials are characterized and studied using several tools, and techniques including SEM/FIB, XRD, UV-Vis, Raman, Hall, PL, XPS, XRF, XANES, AFM and 4 point probe. Tandem devices and single crystal perovskites are also being investigated. Subrate and superstrate PV devices are designed, fabricated, characterized and tested. Light and dark J-V measurements are performed, followed by external quantum efficiency.
