Bifacial semitransparent perovskite solar cells (BS-PSCs) have broad application prospects in the field of building-integrated photovoltaics, tandem solar cells as well as transparent chargeable devices. To fabricate high-performance BS-PSCs, the rear transparent electrode is one of the major obstacles should be overcome. Here, we develop a MoOx/Cu/Ag/MoOx multi-stacked electrode by thermal evaporation, and utilize it as a rear transparent electrode in the fabrication of high-performance n-i-p structure BS-PSCs. It is demonstrated that the minimum thickness required to obtain a continuous Ag film is reduced from 15 nm without the seed layer to 10 nm and the optical and electrical properties of multilayer transparent electrode are significantly enhanced. As a result, the BS-PSC device achieves the optimal power conversion efficiency of 13.44% at indium tin oxide side and 10.25% at MoOx/Cu/Ag/MoOx rear transparent electrode side, along with an average 8.67% optical transmittance for the visible light (400–800 nm) simultaneously. This work provides a promising approach to fabricate high-performance semitransparent and bifacial-operable optoelectronic devices in the future. |
