In recent years, Tio2, a wide band gap semiconductor, has been investigated extensively due to its high surface-to-volume ratio. In organometallic halide perovskite solar cells have lot of attention due to low cost, high efficiency photovoltaic technology. There are lot of optimizing technique for high efficiency perovskite solar cell like perovskite layer morphology, composition, interfaces and charge collection efficiency. In this present work ceramic based mp-Tio2 synthesized by the sol-gel method. The ceramic based mp-Tio2 improved charge collection and charge recombination. The ceramic Tio2 improve cell efficiency and also enhances device stability. |
