Abstract
Air-stable doping of the n-type fullerene layer in an n-i-p planar heterojunction perovskite device is capable of enhancing device efficiency and improving device stability. Employing a (HC(NH ) ) Cs Pb(I Br ) perovskite as the photoactive layer, glass-glass laminated devices are reported, which sustain 80% of their "post burn-in" efficiency over 3400 h under full sun illumination in ambient conditions.
摘要
在 n-i-p 平面异质结钙钛矿器件中，实现 n 型富勒烯层的空气稳定掺杂，能够提高器件效率并改善器件稳定性。采用 (HC(NH ) ) CsPb(I Br ) 钙钛矿作为光活性层，报道了玻璃-玻璃层压器件，在环境条件下，在全阳光照射下经过 3400 小时后，其“烧入后”效率仍保持在 80%。
