Abstract

Although highly conductive poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) has emerged as alternative transparent electrodes to indium thin oxide (ITO), cell-performance is inferior to ITO based polymer solar cells (PSCs). To improve PEDOT:PSS based PSCs, we inserts metal-oxide hole transport layer (HTL) between PEDOT:PSS electrodes and photoactive layers for the first time. Device with optimized vanadium oxide HTL exhibits enhanced power conversion efficiency (PCE) of 3.33% (3.03% for conventional ITO-free PSCs). Improved performance is attributed to the increased shunt resistance and reduced surface roughness of PEDOT:PSS electrodes. Furthermore, improvement in device-stability under the atmospheric condition is observed.
