Application

High-Efficiency Organic Solar Cells (OPVs)
OPV Device Structure: ITO/PEDOT:PSS/PTB7 :PC71BM/Ca/Al

JSC = 14.9 mA/cm2
VOC = 0.75 V
FF = 0.69
PCE = 7.4%

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).[1][2][3][4]

General description

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.[5][6]

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". Hole transport organic materials allow perfect energy level alignment with the absorber layer and therefore efficient charge collection, are prone to degradation in ambient conditions.Click here for more information.
