제목 Energy Level Control of Hole Transporting Materials to Increase Open Circuit Voltage for Highly Efficient Perovskite Solar Cells
초록 A new series of poly(triarylamine) (PTAA)-based conducting polymers with different energy level, especially highest occupied molecular orbital (HOMO), was synthesized as hole transporting materials (HTM). To comprehend the effects of the HOMO of HTM on perovskite solar cells (PSCs) we fabricated the FAPbI3-based PSCs adjusting PTAA derivatives. The deeper HOMO level of HTM led to higher open circuit voltage (VOC), resulted in highly efficient PSC. Thus, the energy level of HTM is related to determining the VOC of PSC, controlling the energy level of HTM is an effective mean of increasing VOC to achieve efficient PSC.
