説明

<jats:title>Organic solar cells tuned by blending</jats:title> <jats:p> Electrical engineers can finetune the energetics of rigid photovoltaics and transistors by blending different semiconducting materials. However, it's hard to apply this tuning protocol to the flexible class of carbon-based semiconductors. Schwarze <jats:italic>et al.</jats:italic> now show that continuous band energy tuning is indeed possible by varying the blend ratios of certain organic phthalocyanines and their fluorinated or chlorinated derivatives (see the Perspective by Ueno). They demonstrated the effect, which they attribute to quadrupolar interactions, in model solar cells. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6292" page="1446" related-article-type="in-this-issue" vol="352" xlink:href="10.1126/science.aaf0590">1446</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6292" page="1395" related-article-type="in-this-issue" vol="352" xlink:href="10.1126/science.aaf8937">1395</jats:related-article> </jats:p>
