有机金属三卤化物钙钛矿太阳能电池提供了一种低成本、易于制造的太阳能技术，与大规模低温溶液处理兼容。在开发的一年内，太阳能到电力的转换效率已经上升到15%以上，预计将进一步提高。在这里，我们表明，这种技术可以成功地与电子受体和供体材料通常用于有机光致发光兼容。我们证明，夹在有机接触之间的低温溶液处理的有机金属三卤化物钙钛矿吸收剂CH 3 NH3 PbI 3-xClx的单个薄膜可以在玻璃基板上显示出高达10%的功率转换效率，在柔性聚合物基板上显示出超过6%的功率转换效率。这项工作代表了向前迈出的重要一步，因为它消除了有机光伏社区采用钙钛矿技术的大多数障碍，因此可以利用混合界面的广泛现有知识进行进一步的设备改进和灵活的处理平台。
Organometal trihalide perovskite solar cells offer the promise of a low-cost easily manufacturable solar technology, compatible with large-scale low-temperature solution processing. Within 1 year of development, solar-to-electric power-conversion efficiencies have risen to over 15%, and further imminent improvements are expected. Here we show that this technology can be successfully made compatible with electron acceptor and donor materials generally used in organic photovoltaics. We demonstrate that a single thin film of the low-temperature solution-processed organometal trihalide perovskite absorber CH3NH3PbI3-xClx, sandwiched between organic contacts can exhibit devices with power-conversion efficiency of up to 10% on glass substrates and over 6% on flexible polymer substrates. This work represents an important step forward, as it removes most barriers to adoption of the perovskite technology by the organic photovoltaic community, and can thus utilize the extensive existing knowledge of hybrid interfaces for further device improvements and flexible processing platforms.
