説明
<jats:title>Perovskite Photovoltaics</jats:title> <jats:p> For many types of low-cost solar cells, including those using dye-sensitized titania, performance is limited by low open-circuit voltages. <jats:bold> Lee <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="643" related-article-type="in-this-issue" vol="338" xlink:href="10.1126/science.1228604">643</jats:related-article> , published online 4 October; see the Perspective by <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6107" page="625" related-article-type="in-this-issue" vol="338" xlink:href="10.1126/science.1230283"> <jats:bold>Norris and Aydil</jats:bold> </jats:related-article> ) have developed a solid-state cell in which structured films of titania or alumina nanoparticles are solution coated with a lead-halide perovskite layer that acts as the absorber and n-type photoactive layer. These particles are coated with a spirobifluorene organic-hole conductor in a solar cell with transparent oxide and metal contacts. For the alumina particles, power conversion efficiencies of up to 10.9% were obtained. </jats:p>
