NEBs (New Energy Batteries) have some advantages that the fossil energy can not match. Dye-Sensitized Solar Battery (DSSB) as a state-of-art technology will not be directly measured for its intrinsic parameters due to its immature technology. Based on the Computer Simulation Technology (CST), this paper integrates the electrochemical and optical processes of DSSBs into account, and conducts a survey on how the externalities are subject to optical properties. The findings show that: screen printing film can prepare the DSSBs with good properties; it is found by simulation that the driving force of the battery attributes to the uneven diffusion of electron concentration distribution caused by chemical action, and the electric field strength and average electron density in open circuit are higher than that in the short circuit. With the CST, battery output properties can be simulated regardless of the internal transport mechanism of the charge. The study in this paper provides the clues to measuring the intrinsic parameters of NEBs.
