近几年来,有机-无机杂化的钙钛矿太阳能电池的效率突飞猛进,仅仅4年时间里,基于这类材料的固态太阳能电池效率已经达到了经过认证的22.1%.该效率能够与商用的硅基太阳能电池相媲美,并且已远超有机太阳能电池和染料敏化太阳能电池的效率.除了可观的效率,相较于其竞争对手,该类材料具有适应于低温/空气中的溶液处理的能力以及更好的柔性,使其在大规模制备上具有成本优势以及能更好地应用于可穿戴电子设备的能力.本文聚焦于柔性及半透明钙钛矿太阳能电池近期的发展.在柔性钙钛矿太阳能电池方面,讨论了两种主要的器件结构：平面型及纤维型;而在半透明钙钛矿太阳能电池方面,则讨论了两种主要的构造策略：减少膜厚及形成孤立的岛状结构.鉴于该类材料的优势和特性,我们可以确信其在柔性及半透明太阳能电池领域的应用潜力,而这些应用也将进一步推动基于该类材料的太阳能电池的发展.

英文摘要：

Organic-inorganic hybrid perovskite solar cells have experienced a skyrocketing photoelectric conversion efficiency （PCE） increase in recent years, and become the ＂rock star＂ in the field of solar cells. After only 4 years, the certificated PCE of these materials based solid state solar cells have reach the maximum 22.1%, which is comparable to the highest PCE of the commercial silicon-based solar cells and higher than those of the organic solar cells and the dye-sensitized solar cells. Besides the promising efficiency, these materials surpass its competitors with the adaptability to solution- process at low-temperature and in air, and better flexibility, which can lead to lower large-scale production cost and more application potential for wearable electronics. The outstanding device performance of the hybrid perovskite solar cells have attracted intensive research interest, and besides increasing the PCE, lots of efforts have been focused on functional diversification for this solar cells. Compare to the commercial solar cells based on rigid silicon, organic- inorganic hybrid perovskite materials exhibit better flexibility which is beneficial for applications in flexible electronic devices, and due to the mild preparation conditions and the solution processablity, it is easy to prepare a variety of nanostructures. Those advantages have expanded the application scope of the hybrid perovskite materials, especially for fabricating flexible and semi-transparent solar cells which have potential use in building integrated photovoltaic such as solar cell windows and solar cell curtains. Here in this review, we focus on the recent progress of the flexible and semi-transparent solar cells based on organic-inorganic hybrid perovskite materials. In the part of the flexible hybrid perovskite solar cells, two mainstream device structures, namely planar and fiber-shaped devices, are discussed and the device structure and materials selection are analyzed in detail. As for the planar flexible perovskite solar cells, th
