Abstract
This paper presents the fabrication of large-area four-terminal (4 T) perovskite-Si solar cells. Large-area semi-transparent perovskite solar cells were fabricated by utilizing a thin copper layer as the low-cost transparent electrode. Carrier selective contact (CSC)-based Si solar cell was also fabricated with molybdenum oxide (MoOx) hole selective layer. Large-area semi-transparent perovskite solar cells (PSCs) with active areas 1 cm2 and 2 cm2 showed a power conversion efficiency (PCE) of 5.07% and 4.10%, respectively. The CSC Si solar cell displayed a PCE of 3.42%. The CSC-Si cell exhibited an efficiency of 2.24% under filtered light when placed under the semi-transparent perovskite top cell. The four-terminal effect was also demonstrated with a commercially available monocrystalline-Si solar cell. The efficiency of commercial c-Si solar cell was 14.11% under 100 mW cm−2 illumination and 10.08% under filtered light. The combined efficiency values of the 4 T configurations with perovskite top cell and the bottom CSC Si cell, and the commercial c-Si solar cell, were 7.31% and 15.15%, respectively. These values were more than the individual cell efficiencies.

摘要
本文介绍了大面积四端 (4 T) 钙钛矿-硅太阳能电池的制造。通过利用薄铜层作为低成本透明电极制造大面积半透明钙钛矿太阳能电池。还使用氧化钼 (MoOx) 空穴选择层制造了基于载流子选择性接触 (CSC) 的 Si 太阳能电池。大面积半透明钙钛矿太阳能电池 (PSC)，有源面积为 1 cm 2和 2 cm 2显示出功率转换效率 (PCE) 分别为 5.07% 和 4.10%。CSC Si太阳能电池的PCE为3.42%。当放置在半透明钙钛矿顶部电池下方时，CSC-Si 电池在滤光下的效率为 2.24%。市售的单晶硅太阳能电池也证明了四端效应。商用 c-Si 太阳能电池的效率在 100 mW cm -2照明下为 14.11%，在过滤光下为 10.08%。具有钙钛矿顶部电池和底部 CSC 硅电池的 4 T 配置以及商用 c-Si 太阳能电池的组合效率值分别为 7.31% 和 15.15%。这些值超过了单个电池的效率。
