摘要：

"Chemical Equation Presented" Sun catcher: The new benzo[l,2-b:4,5-b′]dithiophene-containing polymer PBDTTBT exhibits a power conversion efficiency of up to 5.66%. The high open-circuit voltage (0.92 V) originates from the low HOMO level of the polymer and the high internal and external quantum efficiencies over a wide spectral range. PBDTTBT is a promising donor material for application in polymer solar cells. © 2010 Wiley-VCH Verlag GmbH & Co. KCaA.
