Abstract

Organometal trihalide perovskite material is an exciting class of photovoltaic material with good performance and simple fabrication process that can be adopted by low-cost manufacturable technologies. Unfortunately, such technology is haunted by stability issues for long term applications. To address this issue, recent studies generally trade performance for stability by applying a filter to eliminate UV and blue illumination. Herein, we report our success in using a-Si/perovskite architecture, in which the a-Si is not only part of the device, but also an effective UV-blue light filter to keep perovskite from the UV damage. The tandem device maintains higher performance, particularly during the long term tests. Specifically, Voc of the tandem device achieved a high value of 93% the sum of the component-cells under AM 1.5 illumination. The stability of perovskite solar cells is significantly enhanced comparing with bare perovskite devices. Our results indicate a novel feasible route to elevate the stability of perovskite solar cell without compromising its performance.
