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.
