摘      要：The photovoltaic performance of perovskite solar cells(PSCs)can be improved by utilizing efficient front ***,it has always been a significant challenge for fabricating high-quality,scalable,controllable,and cost-effective front *** study proposes a realistic multi-layer front contact design to realize efficient single-junction PSCs and perovskite/perovskite tandem solar cells(TSCs).As a critical part of the front contact,we prepared a highly compact titanium oxide(TiO2)film by industrially viable Spray Pyrolysis Deposition(SPD),which acts as a potential electron transport layer(ETL)for the fabrication of *** and reproducibility of the TiO2 ETL were discreetly investigated while fabricating a set of planar *** the front contact has a significant influence on the optoelectronic properties of PSCs,hence,we investigated the optics and electrical effects of PSCs by three-dimensional(3D)finite-difference time-domain(FDTD)and finite element method(FEM)rigorous *** investigation allows us to compare experimental results with the outcome from ***,an optimized single-junction PSC is designed to enhance the energy conversion efficiency(ECE)by30% compared to the planar reference ***,the study has been progressed to the realization of all-perovskite TSC that can reach the ECE,exceeding 30%.Detailed guidance for the completion of high-performance PSCs is provided.
