Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Co‐produced</bold>: Using [Co(en)₃]^2+/3+ based‐electrolytes in p‐type dye‐sensitized solar cells (p‐DSCs) gives record energy conversion efficiencies of 1.3 % and open‐circuit voltages up to 709 mV under simulated sun light. The increase in photovoltage is due to the more negative redox potential of [Co(en)₃]^2+/3+ compared to established mediators.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1p994jqg" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
