摘要

半透明钙钛矿太阳能电池（ST-PSCs）在建筑集成光伏发电中显示出巨大的潜力。然而，st - psc的性能仍远未达到其真正的潜力。本文将功能添加剂[4-（三氟甲基）苯基]磺酰氯（TFBSC）加入到钙钛矿前驱体溶液中，以调节钙钛矿结晶过程，减少钙钛矿薄膜中的缺陷。与对照钙钛矿膜相比，TFBSC的加入改善了钙钛矿膜的形貌，提高了载流子寿命和光致发光量子效率。结果表明，经TFBSC修饰的冠军器件的功率转换效率（PCE）为14.75%，光利用效率（LUE）为3.92%，而控制器件的PCE和LUE分别为10.71%和2.96%。此外，未封装的tfbsc修饰的器件在环境条件下（相对湿度为~ 30%-40%）储存1500小时后，其初始PCE保留了~ 90%。这些发现可以为开发用于智能建筑应用的高性能st - psc提供新的途径。

Functional Additive Incorporation Enhances the Performance of Semi-Transparent Perovskite Solar Cells

Semi-transparent perovskite solar cells (ST-PSCs) have shown great potential in building-integrated photovoltaics. However, the performance of ST-PSCs is still far from achieving their true potential. Herein, a functional additive, [4-(trifluoromethyl)phenyl] sulfonyl chloride (TFBSC), is incorporated into the perovskite precursor solution to regulate the crystallization process and reduce defects in the perovskite films. The addition of TFBSC improves the perovskite film morphology and increases the charge carrier lifetime and photoluminescence quantum efficiency, compared with the control perovskite films. As a result, the champion device modified with TFBSC shows a power conversion efficiency (PCE) of 14.75% with a light utilization efficiency (LUE) of 3.92%, whereas the control device shows PCE and LUE values of 10.71% and 2.96%, respectively. Moreover, the unencapsulated TFBSC-modified device retains ∼90% of its initial PCE after 1500 h of storage under ambient conditions (relative humidity of ∼30%–40%). These findings could provide new avenues to develop high performance ST-PSCs for smart building applications.
