Hybrid Inorganic-Organic Perovskite Halide Photovoltaics:

The fundamental scientific and engineering research in the design and realization of new electronic materials for thin film photovoltaics (PV) for flexible electronics is being investigated. A significant portion of this research effort is devoted to investigating, researching and developing special optical materials for thin film PV. Thin film polycrystalline low-cost alternatives to silicon have emerged. Recently, the methylammonium lead tri-iodide CH3NH3PbI3 perovskites have attracted a lot of attention as a possible absorber material for thin film solar cells, due to their bandgap energy, high optical absorption coefficients and low-cost solution-processing deposition approaches. Perovskite absorber materials are very inexpensive to synthesize and simple to manufacture, making them an extremely commercially viable option. Our research focuses on the investigation, study and development of efficient and cost-effective perovskite thin films and solar cells. Our group is also investigating tandem solar cells with perovskite and silicon solar cells; lead-free perovskites with lead replaced by tin; and Gamma and X-ray CZT Room Temperature Radiation Detectors based on Cadmium Zinc Telluride (CZT), a semiconductor material is well suited for good charge collection efficiency and high energy resolution room temperature gamma-ray radiation detection.
