Abstract
Recently the power conversion efficiency of lead (Pb)-based organometallic halide perovskite materials was reached to 23 %. Despite of its excellent performance, the issue of environment and health still remained due to the lead toxicity. Therefore, the double perovskite (A2B'B"X6) which was composed of binary B site cations was particularly investigated as suitable non-toxic and lead-free perovskite composition. In this work, we synthesized all inorganic halide double perovskite composition, Cs2AgBiBr6 with dropping method. Furthermore, the p-i-n double perovskite solar cell was designed and improved by applying various hole and electron transporting layers based on the optimization of band alignment.
