Monolithic perovskite/silicon tandem solar cells have the potential to outperform the efficiency of silicon devices. However, transparent electrode is one of the sensitive factors and challenges for realization of tandem device. Herein, we modify the thickness of buffer layer and sputtering power of transparent electrode for equilibrium between protection of underlying layers and conductivity of electrode. Furthermore, thickness of ITO transparent electrode is varied to realize the optical optimizations. Ultimately, we obtain a monolithic perovskite/silicon-heterojunction tandem solar cell yielding the matched short circuit current density of up to 15.11 mA/cm² measured without any anti-reflective foil. In addition, a bifacial solar cell is also presented based on the semi-transparent perovskite solar cell. These results clearly illustrate the impendency of optical utilization in perovskite/silicon tandem cells. It permits a further step towards the realization of high efficiency tandem solar cells beyond the single-junction silicon cell efficiency limit.

整体钙钛矿/硅串联太阳能电池具有超越硅器件效率的潜力。然而，透明电极是实现串联装置的敏感因素之一和挑战。在此，我们修改缓冲层的厚度和透明电极的溅射功率，以平衡下层的保护和电极的导电性。此外，可以改变ITO透明电极的厚度以实现光学优化。最终，我们获得了整体式钙钛矿/硅-异质结串联太阳能电池，其匹配的短路电流密度高达15.11 mA / cm ²在没有任何防反射箔的情况下进行测量。另外，还提出了基于半透明钙钛矿太阳能电池的双面太阳能电池。这些结果清楚地说明了钙钛矿/硅串联电池中光利用的迫切性。它允许朝着实现单串联硅电池效率极限之外的高效率串联太阳能电池迈出进一步的步骤。
