Wide wavelength IOSCs were characterized by doping the active layer with long wavelength absorbing SnPc.
The hole-transporting layer (HTL) comprised Ag nanoparticles (NPs)-embedded PEDOT:PSS.
The SnPc-doped active layer exhibits a long wavelength absorbing and prevents the active layer from PCBM clusters degrading.
Ag NPs-embedded PEDOT:PSS enhanced the scattering and reflection of light, leading to increase absorption efficiency.
