Organic–inorganic hybrid heterojunction solar cells have gained extensive attention due to the simple device structure and low-cost technological processes, and n-type silicon has been mainly used as the inorganic absorber in previous research. Herein, hybrid heterojunction solar cells based on p-type silicon are successfully prepared through a low-temperature solution method. A preliminary power conversion efficiency over 4% is observed, via optimizing the organic thin-film deposition and organic/inorganic interface, which enhance the built-in field and promote the separation of photogenerated carriers in the heterojunction. Therefore, a new idea and possibility are provided for developing low-cost, high-performance solar cells.

溶液处理的有机/p 型硅混合异质结太阳能电池

有机-无机杂化异质结太阳能电池由于器件结构简单、工艺成本低而受到广泛关注，以往研究主要采用n型硅作为无机吸收体。在此，通过低温溶液法成功制备了基于p型硅的混合异质结太阳能电池。通过优化有机薄膜沉积和有机/无机界面，观察到超过 4% 的初步功率转换效率，这增强了内置场并促进了异质结中光生载流子的分离。因此，为开发低成本、高性能的太阳能电池提供了新的思路和可能性。
