In this work, we demonstrate inverted semitransparent perovskite solar cells (PSC) comprising an indium zinc oxide (IZO) layer sputtered at room temperature without a protective buffer layer between the organic electron transport layers (ETL) and the transparent sputtered electrode. The damage done to the ETL layer during sputtering is cured with a short annealing step at a moderate temperature and semitransparent PSCs with fill factors of almost 70% and with power conversion efficiencies (PCE) over 13% are achieved with negligible hysteresis. We investigate the influence of the layer thicknesses of the ETL double layer consisting of PCBM and BCP on the solar cell characteristics as well as the influence of the illumination direction of the bifacial device.

在这项工作中，我们演示了倒置的半透明钙钛矿太阳能电池（PSC），该电池包括在室温下溅射的氧化铟锌（IZO）层，在有机电子传输层（ETL）和透明溅射电极之间没有保护性缓冲层。溅射过程中对ETL层造成的损坏可以通过在中等温度下短时间的退火步骤来固化，并且半透明的PSC的填充系数几乎为70％，而功率转换效率（PCE）则可以忽略不计，超过13％。我们研究了由PCBM和BCP组成的ETL双层的层厚度对太阳能电池特性的影响以及双面器件的照明方向的影响。
