In this work, anatase N-doped TiO₂ was prepared by a facile pre-sintering method. The usage of N-doped TiO₂ not only improved the electrical performance of the electron transport layer, but prevented high-temperature sintering of the substrate. As a result, the devices with N-doped TiO₂ exhibited higher average power conversion efficiency of 16.65%. Furthermore, N-doped TiO₂ was used in flexible devices, and high performance of flexible perovskite solar cells with power conversion efficiency of 14.52% was achieved. Consequently, the preparation of N-doped TiO₂ could be a promising method for boosting the development of flexible perovskite solar cells.

在这项工作中，锐钛矿型 N 掺杂 TiO ₂是通过简单的预烧结方法制备的。N掺杂TiO ₂的使用不仅提高了电子传输层的电学性能，而且防止了衬底的高温烧结。因此，具有 N 掺杂 TiO ₂的器件表现出更高的平均功率转换效率，为 16.65%。此外，N掺杂的TiO ₂用于柔性器件，实现了功率转换效率为14.52%的高性能柔性钙钛矿太阳能电池。因此，N掺杂的TiO ₂的制备可能是促进柔性钙钛矿太阳能电池发展的一种有前景的方法。
