Hybrid Perovskites Solar Cells
The Organic-Inorganic hybrid perovskites have opened new avenues to develop low cost and high efficiency photovoltaic devices. Perovskites with general formula MAX3 (M=Organic part; A=Pb, Sn; X= Halogens) have attracted significant attention as efficient light harvesters. In particular, CH3NH3PbI3 has been intensely studied over past couple years for solar cell applications. Solar cells based on the hybrid perovskites have shown efficiencies more than 20%, claiming these materials as potential candidates for next generation solar devices. Lead based perovskite solar cells are relatively new devices and modeling of these materials is focused on understanding the materials properties.
Additionally, searching Lead free  hybrid perovskite is another interesting future challenge of this field. We also focus on stability of Guanidinium (GA) based hybrid perovskites GAPbI3 and GAPbBr3 hybrid perovskite along with electronic properties and solar energy conversion efficiency. Further alloying of GAPbI3 will be considered to evaluate formation probability of intermediate alloy. The outcome is planned to be connected with the experimental observations to have a more impact in the scientific community
