利用黑色多晶型甲胺碘铅Hc(NH2)(2)PbI3研制了钙钛矿型太阳能电池，在AM 1.5g单日照条件下，其功率转换效率超过16%。与CH3NH3PbI3相比，HC(NH2)(2)PbI3的吸收峰扩展到840 nm，在296-423K之间没有相变，并且基于HC(NH2)(2)PbI3的太阳电池具有光稳定性和很小的I-V滞后。
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)(2)PbI3. Compared with CH3NH3PbI3, HC(NH2)(2)PbI3 extends its absoprtion to 840 nm and shows no phase transition between 296 and 423 K. Moreover, a solar cell based on HC(NH2)(2)PbI3 exhibits photostability and little I-Vhysteresis.
