The effect of transparent conductive oxide on the performance CH3NH3PbI3 perovskite solar cell without electron/hole selective layers

The effect of transparent conductive oxide (TCO) on the performance of compact-layer free perovskite solar cells has been investigated. The results show that the perovskite film formation, charge transfer and charge recombination are affected by the TCO layer. All common TCOs, including ITO, FTO and AZO, show some beneficial and detrimental characters for solar cell application. Finally, the compact-layer free perovskite solar cells based on them show similar performance.
