摘要：

Hybrid solar cells based on n-Si/poly(3,4-ethylenedioxythiophene): poly

(styrene-sulfonate) (PEDOT:PSS) heterojunction promise to be a low cost photovoltaic technology by using simple device structure and easy fabrication process. However, due to the low conductivity of PEDOT:PSS, a metal grid deposited by vacuum evaporation method is still required to enhance the charge collection efficiency, which complicates the device fabrication process. Here, a solution-processed graphene oxide (GO)-welded silver nanowires (AgNWs) transparent conductive electrode (TCE) was employed to replace the vacuum deposited metal grid. A unique “sandwich” structure was developed by embedding an AgNW network between PEDOT:PSS and GO with a figure-of-merit of 8.6 × 10^�3 Ω^�1, which was even higher than that of sputtered indium tin oxide electrode (6.6 × 10^�3 Ω^�1). A champion power conversion efficiency of 13.3% was achieved, because of the decreased series resistance of the TCEs as well as the enhanced built-in potential (V_bi) in the hybrid solar cells. The TCEs were obtained by facile low-temperature solution process method, which was compatible with cost-effective mass production technology.
