By employing graphene quantum dots (GQDs) in
PSS, we have achieved an efficiency of 13.22% in Si/
PSS hybrid solar cells. The efficiency enhancement is based on concurrent improvement in optical and electrical properties by the photon downconversion process and the improved conductivity of
PSS via appropriate incorporation of GQDs. After introducing GQDs into
PSS, the short circuit current and the fill factor of rear-contact optimized hybrid cells are increased from 32.11 to 36.26 mA/cm(2) and 62.85% to 63.87%, respectively. The organic-inorganic hybrid solar cell obtained herein holds the promise for developing photon-managing, low-cost, and highly efficient photovoltaic devices.
通过在 PEDOT：PSS 中使用石墨烯量子点 (GQDs)，我们在 Si/PEDOT：PSS 混合太阳能电池中实现了 13.22%的效率。这种效率的提高是基于光子下转换过程同时改善光学和电学性质，以及通过适当掺入 GQDs 提高 PEDOT：PSS 的电导率。在将 GQDs 引入 PEDOT：PSS 后，后接触优化混合电池的短路电流和填充因子分别从 32.11 mA/cm(2)增加到 36.26 mA/cm(2)和 62.85%增加到 63.87%。本文获得的有机-无机混合太阳能电池有望开发出用于管理光子、低成本和高效的光伏器件。
