    Perovskite materials have received extensive attention from researchers in the photovoltaic field due to their high carrier mobility, long carrier lifetime, adjustable band gap, convenient preparation and low cost


    Researcher Liu Shengzhong from the Thin Film Solar Cell Research Group of Dalian Institute of Chemical Physics, Chinese Academy of Sciences (DNL1606) found that the method of confined crystallization of ZrSBA-15 mesoporous materials can effectively improve the photoelectric conversion efficiency of inorganic perovskite solar cells

    After ZrSBA-15's restricted crystallization control, 7nm-type single-crystal perovskite crystals with the same channel size as ZrSBA-15 are formed in the inorganic perovskite film, which effectively promotes carrier transport
