中文摘要： 钙钛矿型太阳能电池是近几年提出并得到迅速发展的一类新型太阳能电池，高的吸光系数、高的载流子迁移速率等优异材料特性使其受到学术界的高度关注。目前，钙钛矿型太阳能电池已然成为新能源领域最为重要的研究热点之一。太阳能电池柔性化是太阳能电池制备技术的重要研究方向。柔性化不仅能大大扩展太阳能电池的应用范围，而且能够更加容易实现光伏建筑一体化。更为重要的是，基于柔性基底的太阳能电池适合采用卷对卷技术来制备，这将大大降低电池的制备成本。但是，目前柔性钙钛矿型太阳能电池的性能与人们的期望还相距甚远，研究中还存在许多亟待解决的问题。本项目将钙钛矿电池的柔性与高效两个方面统一起来，重点解决高效钙钛矿太阳电池柔性化制备方法的关键问题。本项目的实施将推动钙钛矿电池的柔性化研究进程，为该类电池的卷对卷低成本、规模化制备技术的开发提供丰富、可靠的基础研究数据和理论，进而加快钙钛矿型电池的商品化进程。

英文摘要： Perovskite solar cells developed fast in the past few years and have attracted more and more attention due to the excellent performances of perovskite materials such as strong solar absorption, low non-radiative carrier recombination rates and high carrier mobility. At present, Perovskite-type solar cell has become one of the most important research focuses in the new energy field.Flexibility of the devices is an important feature for solar cells. The flexible feature can not only greatly expand the scope of application of solar cells but also more easily realize building integrated photovoltaic. More importantly, solar cells on flexible substrate can be prepared by using roll-to-roll technique, which will greatly reduce the manufacturing cost. However, the current performances of flexible perovskite solar cells are still far away from people’s expectations, many problems still exist and need to be solved as soon as possible.The project will focus on solving the key problems existing in the preparation of the perovskite solar cells based on flexible substrates considering both flexibility and efficiency. The successful implementation of the project will promote the development of the perovskite solar cells based on flexible substrates, provide a rich and reliable basic research data for the roll-to-roll preparation of perovskite solar cells, and speed up the commercialization of perovskite solar cells.
