摘要：

For solar cell applications, Sn-based hybrid perovskites have drawn particular interest due to their environmental friendliness. Here, a thin layer of C-60 pyrrolidine tris-acid (CPTA) is found essential for achieving high efficiency with planar solar cells of Sn-based perovskites. As a result, a power conversion efficiency of 7.40% is achieved for {en}FASnI(3) solar cells with a planar n-i-p architecture, and the device exhibits excellent stability in air. For the first time, highly efficient Sn-based hybrid perovskite solar cells on n-i-p architecture are achieved. A V-oc of 0.72 V is highlighted as the highest V-oc ever reported for FASnI(3) solar cells.
