Abstract
Abstract Constructing tandem and multi‐blend organic solar cells (OSCs) is an effective way to overcome the absorption limitations of conventional single‐junction devices. However, these methods inevitably require tedious multilayer deposition or complicated morphology‐optimization procedures. Herein, sequential deposition is utilized as an effective and simple method to fabricate multicomponent OSCs with a double‐bulk heterojunction (BHJ) structure of the active layer to further improve photovoltaic performance. Two efficient donor‐acceptor pairs, D18‐Cl:BTP‐eC9 and PM6:L8‐BO, are sequentially deposited to form the D18‐Cl:BTP‐eC9/PM6:L8‐BO double‐BHJ active layer. In these double‐BHJ OSCs, light absorption is…
