PEG-functionalized graphene quantum dots (GQDs) are shown to promote fast exciton dissociation in organic solar cells. Short-chain PEG promotes the most favorable interaction with other organic layers, and the overall efficiency is improved by 36% when compared to the reference devices. The mechanism of enhancement is shown to be increased absorption due to fewer charges remain-ing in the bound state.
聚乙二醇（PEG）功能化石墨烯量子点（GQDs）被证明可以促进有机太阳能电池中的快速激子解离。与其他有机层具有最有利相互作用的短链 PEG，与参考器件相比，整体效率提高了 36%。增强的机制表现为由于较少的电荷仍然处于束缚态，导致吸收增加。
