Tandem solar cells have the advantage of enhancing the absorption range of polymer solar cells. A three‐terminal tandem cell based on two polymer bulk heterojunctions that have complementary absorption profile is demonstrated. In this device configuration the two subcells are connected in parallel through a common semitransparent metal interlayer and an efficiency of 4.8% with short circuit current of 15.1 mA cm −2 is achieved.
