Monolithic Perovskite solar cells (mPSCs) are the multi-layered organic-inorganic hybrid cells that have been focused due to the affordable cost, ease of fabrication and noteworthy power conversion efficiency (PCE). In this research, we have carried out a systematic study to understand the physical phenomenon inside successive layers of the mpscs using the impedance spectroscopy (IS). This study was performed on the optimized mPSCs with power conversion efficiency over 13%, where CH3NH3PbI3, Perovskite has been used as light absorber. The internal electrical processes at the interfaces of the layers of mPSCs devices have been studied and correlated to produce electrical equivalent circuit of the overall device.

Zinc Oxide (ZnO) has been regarded as a promising electron transport layer (ETL) in perovskite solar cells (PSCs) owing to its high electron mobility. However, the acid-nonresistance of ZnO could destroy organic-inorganic hybrid halide perovskite such as methylammonium lead triiodide (MAPbI3) in PSCs, resulting in poor power conversion efficiency (PCE). It is demonstrated in this work that Nb2O5/ZnO films were deposited at room temperature with RF magnetron sputtering and were successfully used as double electron transport layers (DETL) in PSCs due to the energy band matching between Nb2O5 and MAPbI3 as well as ZnO. In addition, the insertion of Nb2O5 between ZnO and MAPbI3 facilitated the stability of the perovskite film. A systematic investigation of the ZnO deposition time on the PCE has been carried out. A deposition time of five minutes achieved a ZnO layer in the PSCs with the highest power conversion efficiency of up to 13.8%. This excellent photovoltaic property was caused by the excellent light absorption property of the high-quality perovskite film and a fast electron extraction at the perovskite/DETL interface.

See-through colored perovskite solar cells that exploit a dielectric mirror are demonstrated. The dielectric mirror strongly reflects a wide range of visible light back to a photoactive layer for efficient light-harvesting, yielding 10.12% power conversion efficiency, with iridescent semitransparent colors.
