Photoenergy Conversion in p‑Type Cu₂ZnSnS₄ Nanorods and n‑Type Metal Oxide Composites

Single-crystalline Cu₂ZnSnS₄ (CZTS) nanorods with a kesterite crystal phase were synthesized using a facile solvothermal reaction. Thin-film electrodes for p-type CZTS nanorods and n-type metal oxide semiconductor composites were fabricated on mesoporous n-type metal oxide electrodes by introducing the electrodes into a solvothermal condition. The composites exhibited high photocurrent and strong photocatalytic oxidative activity for the decomposition of organic compounds
