A robust inter‐connecting layer for achieving high‐performance tandem polymer solar cells is fabricated and demonstrated in polymer tandem solar cells with a PCE of 7.0%. This layer is optically transparent, electrically conductive, and physically strong. It is revealed that, under light illumination, charges are collected and recombined in the interlayer; under dark conditions, charges are generated and extracted from it.
