Abstract:Four kinds of TiO 2 electrodes with different porosities were prepared by adding different ratios of ethyl cellulous into a Dyesol 18-NRT paste. Higher polymer ratios contributed to the higher porosity of TiO 2 films. All electrodes were spin-coated with spiro-OMeTAD and fabricated into solid-state dye-sensitized solar cells (ssDSCs). This simple method allowed more spiro-OMeTAD penetrated into the more porous TiO 2 films. This result demonstrated the pore-filling effect of hole transport materials on the phot… Show more
In this study, solid state dye-sensitized solar cells (ss-DSSCs) were fabricated with g-C3N4 and Ag co-modified TiO2 nanoparticles as photoanode materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
