2月25日,中国科学院等研究团队在《自然·能源》(Nature Energy)上发表论文Regulating grain growth via Li2SnS3 interphase in kesterite solar cells with certified efficiencies exceeding 15%,报告了一种新型铜锌锡硫硒太阳能电池,可实现超过15%的光电转换效率。研究团队创新性提出Li₂SnS₃界面相调控策略,通过改性阳离子迁移路径,实现Zn²⁺与Sn⁴⁺的迁移平衡。该Li₂SnS₃界面相可选择性包覆Cu₂Sn (S,Se)₃中间相晶粒,成为离子迁移的速率控制层,将界面相中Zn²⁺/Sn⁴⁺的迁移势垒差从Cu₂Sn (S,Se)₃中的0.41eV降至0.21eV,有效促进了更大尺寸、更均匀的高结晶度晶粒的形成。由此,器件的光电转换效率从13.86%大幅提升至15.45%;同时,在1.10 eV带隙下,器件的开路电压突破至602 mV。
