介观太阳能电池(Mesoscopic Solar Cells)作为新一代太阳能电池的突出代表, 具有原材料来源丰富, 制备工艺简单, 光电转换效率高等优点, 从而具有广阔的应用前景. 本工作简要评述了全固态介观太阳能电池从染料敏化太阳能电池(Dye-sensitized solar cells)发展到钙钛矿太阳能电池(Perovskite solar cells)过程中新材料、新技术和新概念的研究进展. 1998年, Grätzel课题组首次将固态有机空穴传输材料spiro-OMeTAD应用到染料敏化太阳能电池中, 制备出全固态染料敏化太阳能电池, 虽然仅获得了0.74%的光电转换效率, 但是却使得全固态染料敏化太阳能电池迅速发展成为介观太阳能电池的重要研究方向. 2012年, Park与Grätzel课题组合作, 使用钙钛矿型吸光材料(CH3NH3)PbI3作为敏化剂, spiro-OMeTAD作为空穴收集层, 制备出光电转换效率达到9.7%的全固态介观太阳能电池, 又被称为钙钛矿太阳能电池. 自此, 基于钙钛矿材料的介观太阳能电池迅速成为太阳能电池领域的研究热点. 目前, 钙钛矿太阳能电池的最高公证效率已经达到20.1%. 钙钛矿太阳能电池作为介观太阳能电池商业化道路上里程碑式的突破, 在材料开发、界面优化以及器件稳定性方面的研究仍充满挑战, 也期待新的突破.

As one of candidates of the next generation solar cells, mesoscopic solar cells offer a wide application prospect due to the advantages of abundant raw materials, simple fabrication process, high power conversion efficiency and so on. This review presents a brief overview on the progress of solid-state mesoscopic solar cells in new materials, new technologies and new concepts from dye-sensitized solar cells to perovskite solar cells. In 1998, Grätzel group firstly incorporated solid-state organic hole transport materials spiro-OMeTAD into dye-sensitized solar cell, and fabricated an all-solid-state dye-sensitized solar cell. Though this device only obtained an efficiency of 0.74%, all-solid-state dye-sensitized solar cells became an important direction in the field of mesoscopic solar cells. In 2012, Park group and Grätzel group employed a perovskite absorber (CH3NH3)PbI3 as the sensitizer, and spiro-OMeTAD as the hole collecting layer, developing an all-solid-state mesoscopic solar cell, which was also named perovskite solar cell, with the efficiency of up to 9.7%. Since then, mesoscopic perovskite solar cells based on perovskite materials quickly become a hot topic in the field of solar cell. Presently, the highest certificated power conversion efficiency of perovskite solar cells has reached to 20.1%. As a milestone in the development history of mesoscopic solar cells, perovskite solar cells still have many challenges in material developing, interface engineering, and device stability, and are expecting new breakthroughs in the future.
