Using self-assembly technology to fabricate silver particle array for organic photovoltaic devices

►We design a high-efficiency OPV composed of ITO/ P3HT:PCBM/ ANPA/ Ag film/ glass substrate. ► The ANPA used in this OPV can effectively excite LSP and enhance the light absorption efficiency. ► An up to 22-fold light absorption enhancement at 790nm is achieved in simulation. ► The ANPA can be easily fabricated through the poly-styrene sphere self-assembly technology.
