Abstract

Perovskite solar cells with power conversion efficiencies exceeding 16% at AM 1.5G one sun illumination are developed using the black polymorph of formamidnium lead iodide, HC(NH₂)₂PbI₃. Compared with CH₃NH₃PbI₃, HC(NH ₂)₂PbI₃ extends its absoprtion to 840 nm and shows no phase transition between 296 and 423 K. Moreover, a solar cell based on HC(NH₂)₂PbI₃ exhibits photostability and little I-V hysteresis.
