6-n,n-diarylsubstituted 1h-pyrazolo[3,4-b]quinoxalines-novel Materials For Single-layered Photovoltaic Devices

摘要

At present work organic single layered photovoltaic device, which can use polaron-assisted transport has been developed using a ITO/PEDOT:PSS (poly(3,4-ethylene dioxythiophene)-poly-(styrene sulphonate)/Active Layer/Al) architecture. We have achieved a large photovoltaic response for single layered device (yielding up to 0.82%) by varying the values of state dipole moments of the chromophore. Interaction of chromophore with polymer chains and resulting polaronic transport mechanism seems to be very important as well.
