摘要：

A ternary blend approach to enhance light harvesting is reported by utilizing ladder-type donor polymers with complementary absorption in polymer solar cells. The broader absorption range can be universally achieved by blending individual ladder-type polymers without changes to their electronic properties and morphologies with boosted photocurrent in photovoltaic devices. This method presents a universal and efficient way to absorb wide-spectrum light by using simple processing conditions. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
