A research team led by Prof. Xu Jixian from the University of Science and also Technology of China (USTC) of the Chinese Academy of Sciences (CAS) developed and fashioned a novel porous insulator contact (PIC) for perovskite solar cells. The PIC alleviated the non-radiative fee recombination result and also the matching solar cell accomplished a performance of up to 25.5%. The research was published in Science.

As an appealing photovoltaic or pv material, metal halide perovskite yields high efficiency in solar cells. Nonetheless, the deep-level traps of minority service providers at the surface of the p-i-n perovskite solar cells can reduce nonradiative recombination. The accurate passivation of deep-level traps has actually been a major emphasis in increasing the power conversion efficiency (PCE) to the theoretical Shockley-Queisser restriction.
