Lead-freeand more air-stable perovskite Cs2SnI6 absorber with a direct bandgapof 1.48 eV is synthesized via a modified solution process. Differentnanostructured ZnO nanorod arrays as electron transport layers andhole blocking layers are grown by controlling the seed layer and used tofabricate mesoscopic perovskite solar cells with Cs2SnI6as light absorber layer. Theinfluences of ZnO seed layers and nanorod morphology on the device photovoltaic performance were also investigated. With careful control of ZnO nanorod length andpore size to ensure high loading of the Cs2SnI6 absorber,we achieved power conversion efficiency of near 1%.
