报告简介：
铅卤素钙钛矿是目前最具前景的下一代光电材料体系，但其面临环境友好性低和光活性区间窄的挑战。锡钙钛矿和铅钙钛矿具有类似的电子结构和光电性质，并具有环境友好性高，光活性范围宽的优点，为铅钙钛矿提供了重要补充，但锡基钙钛矿具有高空位缺陷浓度和易氧化的缺点，限制了器件性能的提高。我们课题组提出了利用电子结构调控抑制锡钙钛矿氧化的思路，基于该设计理念开发了准二维结构锡基钙钛矿太阳能电池材料体系，有效降低了锡钙钛矿的氧化和缺陷密度，并进一步通过提高薄膜中晶体的取向性和载流子传输层能带匹配等方法，持续提升了锡基钙钛矿太阳能电池效率，实现了锡钙钛矿太阳能电池第三方认证最高效率纪录，相关方法获得了广泛应用。本次报告将介绍我们课题组在锡基钙钛矿材料维度调控及其在太阳能电池、发光器件和光探测器的应用方面的研究，以及相关领域的研究进展。
