The single-crystalline silicon solar cell with tunnel oxide passivating poly-Si contact (TOPCon) has developed into one of the most promising and high-performance n-type Si-based solar cells in their mass production way because of its high conversion efficiency and robustness. Owing to its unique device structure, TOPCon shows superior advantages over amorphous Si-based heterojunction one (HJT) in developing high-performance monolithic perovskite/silicon tandem solar cell because TOPCon may have better tolerance than HJT to the particle bombardments and plasma fluorescence irradiations in the sputtering deposition process of transparent conductive oxide (TCO) recombination layer. Herein, bathocuproine (BCP):silver complex is introduced as a buffer recombination contact between TCO and poly-SiCX, to modulate the tunneling junction between perovskite/TOPCon. Depending on fine film thickness and derived energy level tuning, BCP:Ag buffer layer can effectively prevent the sputter bombardments and passivate the interface of TCO/poly-SiCX(n)/SiOX contact, as well as enhancing electron transport. As a result, a certified conversion efficiency of 25.84% is achieved in the monolithic perovskite/TOPCon silicon tandem solar cell. This work definitely paves a new and promising way to develop high-performance monolithic perovskite/c-Si tandem solar cells.

浴铜灵：用于高效单片钙钛矿/TOPCon 硅串联太阳能电池的银络合物功能化隧道结
具有隧道氧化物钝化多晶硅接触的单晶硅太阳能电池（TOPCon）由于其高转换效率和可量产性，已发展成为最有前途的高性能n型硅基太阳能电池之一。鲁棒性。由于其独特的器件结构，TOPCon 在开发高性能单片钙钛矿/硅串联太阳能电池方面显示出优于非晶硅基异质结一（HJT）的优势，因为 TOPCon 可能比 HJT 对粒子轰击和等离子体荧光辐射具有更好的耐受性透明导电氧化物（TCO）复合层的溅射沉积工艺。在此，引入浴铜灵 (BCP)：银络合物作为 TCO 和多晶 SiC X之间的缓冲复合接触，调制钙钛矿/TOPCon 之间的隧道结。根据精细的膜厚度和衍生的能级调整，BCP:Ag 缓冲层可以有效地防止溅射轰击并钝化 TCO/poly-SiC X (n)/SiO X接触的界面，并增强电子传输。因此，单片钙钛矿/TOPCon 硅串联太阳能电池的认证转换效率为 25.84%。这项工作无疑为开发高性能单片钙钛矿/c-Si 串联太阳能电池铺平了一条新的、有前途的途径。
