Energy levels of the first monolayer are manipulated at donor/acceptor interfaces in planar heterojunction organic photovoltaics by using molecular self-organization. A "cascade" energy landscape allows thermal-activation-free charge generation by photoirradiation, destabilizes the energy of the interfacial charge-transfer state, and suppresses bimolecular charge recombination, resulting in a higher open-circuit voltage and fill factor.
通过分子自组装，可以在平面异质结有机光伏器件的给体/受体界面上对第一层分子的能级进行调控。“级联”的能量景观允许通过光辐照进行无需热激活的电荷产生，使界面电荷转移态的能量不稳定，并抑制双分子电荷复合，从而获得更高的开路电压和填充因子。
