摘要

有机卤化物过氧化物因其易于合成和高性能而成为太阳能电池中前景广阔的光收集材料。Pi-n 结构的过氧化物太阳能电池具有加工温度低（150 °C）的优势，可应用于柔性太阳能电池。然而，富勒烯电子收集器的高成本和低稳定性限制了它们的应用。在这项研究中，我们开发了一种基于溶液的方法，利用卤化钛前驱体在室温下合成二氧化钛，并将其用作电子收集器。通过在环境空气中氧化 TiI4，在不使用真空工艺的情况下形成了均匀致密的 TiO2。其功率转换效率（PCE）达到了 12.6%。我们的研究为大规模合成高效且经济实惠的太阳能电池铺平了道路。

Inverted-Structured Perovskite Solar Cells with a TiO2 Electron-Collector Layer Formed at Room Temperature from Titanium Halide Solutions

Organohalide perovskites are promising light-harvesting materials for solar cells because of their ease of synthesis and high performance. P-i-n-structured perovskite solar cells have the advantage of a low processing temperature (<150 °C) for applications in flexible solar cells. However, they are limited by the high cost and low stability of fullerene electron collectors. In this study, we developed a solution-based method for synthesizing TiO₂ at room temperature using titanium halide precursors and employed it as an electron collector. Uniform and dense TiO₂ was formed without using vacuum processes by the oxidation of TiI₄ in ambient air. A power conversion efficiency (PCE) of 12.6% was obtained. Our study paves the way for synthesizing efficient and affordable solar cells at a mass scale.
