Current affairs: Acceptor‐substituted squaraines exhibit unprecedented short‐circuit current density of up to 12.6 mA cm−2 in small‐molecule‐based solution‐processed bulk heterojunction (BHJ) solar cells (see picture). These values are closing the gap to polymer solar cells and together with the NIR absorption of the new cells may lead to wide applications.
时事:受体取代的方晶在基于小分子的固溶异质结(BHJ)太阳能电池中表现出前所未有的短路电流密度,高达12.6 mA cm -2(见图)。这些值正在缩小与聚合物太阳能电池的差距,并且与新电池的NIR吸收一起可能会导致广泛的应用。
