We prepared nanopastes containing various additives such as acetylene black (AB paste), 3,5-dinitrosalicylic acid (NSA paste) and SiO2 particles (SO paste), and these nanopastes were employed in preparation of photoelectrodes for dye sensitized solar cells (DSSCs). Photoelectrodes of AB, NSA and SO paste have characteristics of large pore size, superior interconnection among particles, and scattering due to spherical particle shape, respectively. Photovoltaic parameters of cells formed from the pastes were compared with cell formed from the paste without additive. Among the pastes, AB paste exhibited the best cell efficiency improvement of 9.647%. NSA paste also exhibited considerable cell efficiency improvement without much deleterious impact on transparency. The advantages and disadvantages of each nanopastes were analysed for the commercialization of DSSCs.
