摘要

锡铅钙钛矿中存在各种缺陷,且Sn²⁺容易被氧化成Sn⁴⁺,从而导致太阳电池的转换效率和稳定性较差。研究发现4-香豆酸（p-C）的引入可显著改变薄膜的表面形貌、有效提高结晶性,且抑制Sn²⁺的氧化,有利于提高钙钛矿层与传输层之间的能级匹配度。通过对钙钛矿光吸收层的缺陷进行钝化,可显著提升太阳电池的光电特性。最终,锡铅钙钛矿太阳电池的开路电压提升65 mV,光电转换效率由18.14%提升至20.37%,并且电池稳定性得到显著提升。

Abstract

Various defects exist in tin-lead alloyed perovskites, and Sn²⁺ is easily oxidized to Sn⁴⁺, which lead to poor power conversion efficiency （PCE） and stability of solar cells. It is found that the introduction of p-Coumaric acid modifies the surface morphology of the film, effectively improves the crystallinity, and inhibits the oxidation of Sn²⁺, which is conducive to the matching degree of energy levels between the perovskite layer and the transport layer. The photovoltaic characteristics of the device are significantly enhanced through passivating the defects in the perovskite layer. Ultimately, the open-circuit voltage of the tin-lead perovskite solar cell is enhanced by 65 mV. The PCE is increased from 18.14% to 20.37%, and the stability of the device is effectively improved.
