标题:具有超窄带隙的小分子受体的设计,合成和光伏表征
摘要:窄带隙(nbg)供体或受体的设计及其在有机太阳能电池(osc)中的应用在将太阳光子转换为电子方面非常重要.受光伏材料光带隙到osc设备开路电压不可避免的能量损失的限制,基于nbg的osc的功率转换效率(pce)的提高面临巨大挑战.据报道,一种新型的受体-供体-受体结构化的非富勒烯受体具有1.24 Ev的超窄带隙,这是通过增强分子内电荷转移(ict)效应实现的.在osc器件中,尽管能量损失仅为0.509 Ev,但短路电流密度却高达25.3 Ma Cm-2仍会记录,这是所有osc设备的最大值.基于nbg的osc的pce高达10.9%,这表明超窄材料的设计和应用具有进一步改善osc设备pce的潜力.
