For highly efficient photovoltaic, all the photo-generated carriers should be collected at the electrode. Before reaching the electrode these photo-generated charge carrier undergoes various loss mechanisms. These types of losses have a direct consequence on the PV efficiency. To reduce such losses transport path should be low resistive and trap free. This can be achieved by maintaining the balanced electron and hole mobility of active layer, high conducting transport layers, and making the ideal Schottky and Ohmic contact. In this work, dual and triple nanoparticles were embedded in PEDOT:PSS and the effect of nanoparticle on PV performance is investigated. Metal nanoparticle in the HTL manipulate optoelectronic properties. This work provides some insight in the organic photovoltaics while using metal nanoparticle in the HTL. Primary factor for the enhancement in the efficiency is due to the plasmonic behavior and the improved conductivity of HTL. Obtained result indicates that device with triple nanoparticle HTL showed high PCE than dual nanoparticle and neat devices. Further, the experimental PV results were compared with the simulation results. Results suggest that metal nanoparticle in HTL primarily enhances the short circuit current density and fill factor.
