The silicon solar cells currently on the market have an intensive manufacturing process that drives up their cost and energy payback times. Dye-sensitized solar cells (DSSCs) promise lower fabrication costs and have efficiencies comparable to amorphous silicon solar cells.<\/p>\n<p>Tandem DSSCs (formed by combining n-type photoanodes and p-type photocathodes in a single cell) can achieve high efficiencies because the dual dye-sensitized photoelectrodes can provide absorption across the solar spectrum. However, current tandem-cell DSSC technologies are limited by the photocathode\u2019s substandard performance.<\/p>\n<p>&nbsp;<\/p>\n<p>We seek to fabricate highly-efficient dye-sensitized solar cell photocathodes through&#8230;<\/p>\n<ul>\n<li>Investigating the device physics of DSSCs<\/li>\n<li>Introducing new nanostructured p-type semiconductors with proper valence band (VB) positions, high visible transparency, and high hole mobility<\/li>\n<li>Developing new dye molecules with tunable charge transfer bands, appropriate oxidation and reduction potentials, and other properties useful for a wide range of photo-sensitized applications<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>Recently, our <a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/anie.201500274\/abstract\" target=\"_blank\" rel=\"noopener\">research into p-type semiconductors has found results<\/a> which challenge conventional wisdom in the semiconductor field. Not only does n-type semiconductor tin-doped indium oxide (ITO) work as a p-type semiconductor, it also produces high photocurrents. This research shows an alternative path to industry-standard p-type semiconducting films like parasitically-absorbing nickel oxide (NiO).<\/p>\n<div id=\"attachment_74\" style=\"width: 310px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/research.cbc.osu.edu\/wu.531\/wp-content\/uploads\/2015\/05\/ITO-Toc.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-74\" class=\"wp-image-74 size-medium\" src=\"https:\/\/research.cbc.osu.edu\/wu.531\/wp-content\/uploads\/2015\/05\/ITO-Toc-300x258.jpg\" alt=\"\" width=\"300\" height=\"258\" srcset=\"https:\/\/research.cbc.osu.edu\/wu.531\/wp-content\/uploads\/2015\/05\/ITO-Toc-300x258.jpg 300w, https:\/\/research.cbc.osu.edu\/wu.531\/wp-content\/uploads\/2015\/05\/ITO-Toc.jpg 554w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-74\" class=\"wp-caption-text\">A p-type dye-sensitized indium tin oxide (ITO) solar cell.
