Nano Energy（IF=16.602）has published A critical review of materials innovation and interface stabilization for efficient and stable perovskite photovoltaics, by Prof. Mai Yaohua's group in JNU's School of Microelectronics. Wang Yousheng, the associate research fellow, is the lead author and corresponding author, and JNU is the first communication unit. This paper is a collaboration with Jeonbuk National University in South Korea.

In one of the most promising new photovoltaic technologies for industrialization, the monochromatic incident photon-to-electron conversion efficiency (IPCE) of perovskite solar cells has reached 25.5% in just 10 years, and the stability is comparable to widely commercialized solar cells such as silicon. However, the stability of perovskite solar cells still limits its rapid commercialization.

The author pointed out that further research was needed on the chemical interaction between perovskite thin films and additive and the interaction between perovskite film layer and interface contact layer, as well as on the mechanism to improve the efficiency and stability of related devices. This review also includes a guide to selecting useful material in light absorption layers of perovskite-based composites, optimizing the device's structure, and providing highly efficient and stable perovskite photovoltaics devices.
