N2 - Tandem solar cells are found to be promising in organic photovoltaic research because they can double open-circuit voltage (Voc) and utilize photon energy efficiently, as compared to single junction solar cells. In a typical tandem polymer solar cell, two single subcells are staked and connected by an interconnecting layer, which is a prerequisite to achieving high photo-electron conversion efficiency. In this work, a low temperature solution processed and chemically stable PEDOT:PSS/AZO/PEIE interconnecting layer is reported. Tandem polymer solar cells based on this efficient layer can realize a high Voc, which can sum the Voc[U+05F3]s of subcells. Furthermore, the operation mechanism of the interconnecting layer is discussed to help better understand the electron recombination process in the interconnecting layer.
