【摘要】 有机-无机杂化钙钛矿（MAPbI₃）材料已成为光电器件领域的先进材料,但铅元素的存在带来的环境污染问题严重影响钙钛矿材料的实际应用.以无毒性金属元素部分取代铅元素是推进其应用进程的途径之一.选用氯化铜和醋酸铜作为铜元素掺杂源,利用一步法合成铜掺杂钙钛矿薄膜,研究不同铜源对MAPbI₃薄膜成膜质量和光学性质的影响,并揭示影响机制.更多还原

【Abstract】 Organic-inorganic hybrid perovskite（MAPbI₃） materials have become the advanced materials in the field of optoelectronic devices.However,the environmental pollution caused by the presence of lead elements seriously affects the practical application of perovskite materials.The partial replacement using with the non-toxic metal elements is one of the ways to prompt its application process.In this work,cupric chloride and copper acetate were selected as the doping sources for copper.The copper-doped perovskite films were synthesized by one-step method.The effects of different copper sources on the quality and optical properties of MAPbI₃ films were studied,and the influencing mechanism was also revealed.更多还原
