Abstract
We demonstrate the improvement in performance of inverted organic solar cells fabricated with an Ag-nanoparticle (NP) modified ZnO-electron transport layer. Ag NP incorporation into the ZnO layer increases light harvesting efficiency of the solar device which untimely improves Jsc of the device. As a result, power conversion efficiency (PCE) of ZnO + Ag Np buffer layer based (ITO/ZnO:Ag NP/P3HT: PCBM/MoO3/Ag) device reaches 3.02 % which is 27 % higher than ITO/ZnO/P3HT: PCBM/ MoO3/Ag device and 55.6 % higher than the electron transfer layer(ETL) free (ITO/P3HT: PCBM/ MoO3/Ag) control device.
