摘要
在众多的新型太阳电池中,钙钛矿太阳电池以空前的发展速度脱颖而出,其理论转化效率可达50%,是目前商业化太阳电池的2倍。钙钛矿太阳电池制备工艺简单,主要包括溶液法和双源共蒸发,以此制备了电子传输层为多孔态、介孔态、平面态的钙钛矿太阳电池。从电池结构出发,介绍了结构中各功能层的主要作用,重点阐述了电子传输层薄膜的形态变化和钙钛矿吸收层薄膜的制备方法。最后介绍了钙钛矿太阳电池面临的问题,并对其未来发展方向进行了展望。
Perovskite solar cells, with the theoretical efficiency of 50%, which is two times as that of the present commercial solar cells, have been attracted intensively interesting duo to its unprecedentedly developing speed among many novel solar ceils. Since the simple preparation process of the perovskite solar cells, mainly including the solution processing and dual-sourcethermal evaporation, the perovskite solar cells with porous state, mesoporous state, and planar state electron transport layer are prepared. Based on the structure of solar cells, the main function of the each functional layer in solar cell was introduced, and the variation of morphology in electron transport layer and the preparation of the perovskite film are emphatically expounded. At the end, the problems that perovskite solar cells faced with are introduced, and the tendencies of future development are suggested.
