中文摘要

器件兼容功能层的自组装工艺是一种简单、可行和节能的策略。在介孔钙钛矿太阳能电池(perovskite solar cells, PSCs)中，致密的TiO₂膜起到空穴阻挡层的作用，而介孔的TiO₂膜起到电子传输层的作用。然而，这两层通常都要通过高温退火法获得。在此，我们通过室温自组装工艺沉积了致密的TiO₂薄膜，以作为PSCs有效的空穴阻挡层。通过沉积时间控制致密TiO₂薄膜的厚度。优化致密TiO₂薄膜的厚度(80 nm)，有无空穴传输层的介孔PSCs的能量转化效率分别为17.95%和10.66%。值得注意的是，基于自组装TiO₂的全低温PSCs显示出16.41%的能量转化效率。

Self-assembled TiO₂ hole-blocking layers for efﬁcient perovskite solar cells

Abstract

Abstract

The self-assembly process for compatible functional layers of devices is a simple, feasible, and energy-saving strategy. In mesoporous perovskite solar cells (PSCs), compact and scaffold TiO₂ films generally function as the hole-blocking and electron-transporting layers, respectively. However, both of these layers are usually generated through a high-temperature annealing process. Here, we deposited TiO₂ compact films through a room-temperature self-assembly process as effective hole-blocking layers for PSCs. The thickness of TiO₂ compact films can be easily controlled by the deposition time. Through the optimization of TiO₂ compact films (80 nm), the power conversion efficiency (PCE) of mesoporous PSCs without and with hole conductor layers increases up to 10.66% and 17.95%, respectively. Notably, an all-low-temperature planar PSC with the self-assembled TiO₂ layer exhibits a PCE of 16.41%.
