Solution‐Processed Organic/p‐Type Silicon Hybrid Heterojunction Solar Cells.

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. [ABSTRACT FROM AUTHOR]
