Title: | Si hybrid solar cells with 13% efficiency via concurrent improvement in optical and electrical properties by employing graphene quantum dots | Authors: | Tsai, ML Wei, WR Tang, L Chang, HC Tai, SH Yang, PK Lau, SP Chen, LJ He, JH |
Issue Date: | 26-Jan-2016 | Source: | ACS nano, 26 Jan. 2016, v. 10, no. 1, p. 815-821 | Abstract: | By employing graphene quantum dots (GQDs) in PEDOT:PSS, we have achieved an efficiency of 13.22% in Si/PEDOT: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 PEDOT:PSS via appropriate incorporation of GQDs. After introducing GQDs into PEDOT:PSS, the short circuit current and the fill factor of rear-contact optimized hybrid cells are increased from 32.11 to 36.26 mA/cm2 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. | Keywords: | Downconversion Graphene Hybrid solar cell PEDOT:PSS Quantum dot |
