Low-Temperature Solution-Processed Perovskite Solar Cells with High Efficiency and Flexibility Abstract:
Perovskite compounds have attracted recently great attention in photovoltaic research. The devices are typically fabricated using condensed or mesoporous TiO2 as the electron transport layer and 2,207,70-tetrakis-(N,N-dip-methoxyphenylamine)9,90-spirobifluorene as the hole transport layer. However, the high temperature processing (450°C) requirement of the TiO2 layer could hinder the widespread adoption of the technology. In this report,we adopted a low-temperature processing technique to attain high efficiency devices in both rigid and flexible substrates, using device structure substrate/ITO/PEDOT:PSS/CH3NH3PbI3_xClx/PCBM/Al, where PEDOT:PSS and PCBM are used as hole and electron transport layers, respectively. Mixed halide perovskite, CH3NH3PbI3_xClx, was used due to its long carrier lifetime and good electrical properties. All of these layers are solution-processed under 120°C. Based on the proposed device structure, power conversion efficiency (PCE) of 11.5% is obtained in rigid substrates (glass/ITO), and a 9.2% PCE is achieved for a polyethylene terephthalate/ITO flexible substrate.
