摘要：Various approaches of interface engineering are shown to be effective in improving the device performance of organic-inorganic hybrid perovskite solar cells (PSCs). The modification of the photoactive layer of PSC, CH3NH3PbI3 (MAPbI(3)), by spin-coating a layer of p-aminobenzoic acid (PABA), which can significantly enhance the open-circuit voltage (V-OC), the fill factor (FF), and the power conversion efficiency (PCE) of PSCs, is herein reported. The champion device shows a short-circuit current ...More
Various approaches of interface engineering are shown to be effective in improving the device performance of organic-inorganic hybrid perovskite solar cells (PSCs). The modification of the photoactive layer of PSC, CH3NH3PbI3 (MAPbI(3)), by spin-coating a layer of p-aminobenzoic acid (PABA), which can significantly enhance the open-circuit voltage (V-OC), the fill factor (FF), and the power conversion efficiency (PCE) of PSCs, is herein reported. The champion device shows a short-circuit current (J(SC)) of 22.83 mA cm(-2), V-OC of 1.167 V, FF of 0.768, and PCE of 20.47%. The improvement in photovoltaic performance is attributed to the suppression of carrier trap states and the improvement in the morphologies of perovskite films. This work demonstrates a simple and effective protocol to enhance the device performance, and provides an insight into the influence of PABA post-treatment on the charge carrier dynamics. ...Hide
