In order to compete with the larger power markets and improve the implementation of solar cells for utility-scale power generation, a significant increase in efficiency is required for emerging technologies. Originating from research on solution-processable semiconductors, a family of perovskite (“Perovskites” is the terminology for any materials that adopt the same crystal structure as ABX3, i.e., calcium titanate) materials has emerged as a serious contender for utility-scale solar power. These solar cells are based on methylammonium lead trihalide perovskite absorbers; promise to break the prevailing paradigm by combining both low cost and high efficiency with reported power conversion efficiencies high as 17%. Advanced characterization of organometal trihalide perovskite solar cells, is well underway, yielding highly significant data. However, studies of isolated perovskite thin films under working conditions in aspect of solar cells are still scarce. Presented here is Photoconductivity data of MAPbI3 deposited between two gold electrodes spaced 500-2500nm apart.
