摘要
Current affairs: Acceptor-substituted squaraines exhibit unprecedented shortcircuit current density of up to 12.6 mAcm-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. © 2009 Wiley-VCH Verlag GmbH &. Co. KGaA.
