Novel hybrid polymer photovoltaics made by generating silver nanoparticles in polymer:fullerene bulk-heterojunction structures

Here, we developed the high efficient poly(3-hexylthiophene) (P3HT):[6,6]-phenyl C-61-butyric acid butyl ester (PCBB):Ag nanoparticle hybrid photovoltaic cells by generating the silver nanoparticles in the bulk-heterojunction structures of P3HT:PCBB prior to the spin-coating process. Hybrid bulk-heterojunction solar cells with an ITO/(G)-PEDOT/P3HT:PCBB:Ag/A1 was fabricated, which shows open- circuit voltage, short-circuit current density, and power conversion efficiency of 0.639V, 12.29mA/cm(2), and 4.30% under AM1.5 irradiation (100 mW/cm(2)), respectively.
