Abstract

Recently, perovskite solar cells (PSCs) exhibits tremendous power conversion efficiency and has shown enhanced figures of merit being secured regarding cell stability. In this paper, perovskite solar cell with Zno electron injection layer is presented. The humidity degradation of the perovskite active layer and the efficiency of the cell is observed under several conditions. Using ZnO as a planner electron injection layer (EIL) instead of TiO2, the efficiency of the device significantly improved, showing low-resistance shunting pathways. Also, polydimethylsiloxane (PDMS) has been used as a hydrophobic transparent coating layer and its thickness adjusted to make it works as antireflective coating (ARC). This process ultimately mitigates the degradation rate and increase the cell optical absorption. The results confirm the importance of the homogenous surface of EIL and how the PDMS-AR layer could significantly enhance the cell efficiency.

以PDMS为增透涂层的ZnO电子注入层对钙钛矿太阳能电池界面进行改性。

近年来，钙钛矿太阳能电池(PSCs)表现出巨大的能量转换效率，并在电池稳定性方面显示出更高的价值。本文介绍了一种具有Zno电子注入层的钙钛矿太阳能电池。在不同条件下观察了钙钛矿活性层的湿度降解和电池效率。采用ZnO代替TiO2作为规划电子注入层(EIL)，器件效率显著提高，呈现出低电阻的分流路径。采用聚二甲基硅氧烷(PDMS)作为疏水透明涂层，并对其厚度进行调整，使其具有抗反射涂层(ARC)的功能。这一过程最终减轻了降解率，增加了细胞的光吸收。结果证实了EIL均匀表面的重要性，以及PDMS-AR层如何显著提高电池效率。
