Overview

PTB7 is a semiconducting polymer used in organic photovoltaics with an energy efficiency of 9.15%. It can act as an electron donor with narrow optical band gaps and excellent π-π conjugation while forming a nanocomposite with fullerenes.It is majorly used as an active layer that enhances the overall performance by increasing the light absorption and improving the electron mobility of polymeric solar cells (PSCs).High-Efficiency Organic Solar Cells (OPVs)OPV Device Structure: ITO/PEDOT:PSS/PTB7 :PC71BM/Ca/AlJSC = 14.9 mA/cm2VOC = 0.75 VFF = 0.69PCE = 7.4%
