首次将易于制备、直接转移的薄纳米多孔金用作无空穴传输材料的钙钛矿型太阳能电池的背电极。为了将CH3NH3PbI3渗透到介孔层和纳米金背电极的孔道中，采用了一步旋涂沉积、连续沉积和两步旋涂沉积三种方法制备CH3NH3PbI3。掺入较好的CH3NH3PbI3的器件的功率转换效率最高，为7.99%。
Easily fabricated, directly transferred thin nanoporous gold was first used as a back electrode for hole-transport-material-free perovskite solar cells. In order to infiltrate CH3NH3PbI3 into the pores of mesoporous layers and the nanoporous gold back electrode, three ways, namely one-step spin-coating deposition, sequential deposition, and two-step spin-coating deposition were introduced to fabricate CH3NH3PbI3. The devices containing well infiltrated CH3NH3PbI3 show the highest power conversion efficiency of 7.99%.
