摘要：Wide-bandgap perovskite single crystals with high optical transparency and outstanding electronic transport capacity are promising building blocks in semi-transparent solar cells. However, surface defects and residual solvent contamination on single crystals severely compromise charge extraction and lead to non-radiative recombination. Here, we address this challenge by a liquid cleaning approach that effectively removes residual precursors and eliminates surface defects of MAPbBr3 thin single crystal. We integrate an indium tin oxide (ITO)/Ag/ITO composite electrode to balance high conductivity and excellent transmittance, which give rise to first reported semi-transparent single crystal solar cells with a power conversion efficiency (PCE) of 4.92% and an average visible transmittance (AVT) of 59.1%. This synergistic strategy of interface optimization and electrode design broaden the application scope for perovskite single crystals into transparent electronics, and may offer critical wide-gap units for advanced tandem photovoltaics.
