Dye-sensitized solar cell (DSSC) utilizing nanotechnology and photosynthesis attracts much attention due to its high solar-to-electricity conversion efficiency, low cost and colorful appearance. Basic components in DSSC are the nanocrystalline TiO2 film, the dye and the redox electrolyte, where charge is generated by dye and TiO2 film acts as both charge separation and electron transport. In DSSC, high conversion efficiency depends on photocurrent density, photovoltage and fill factor. Photocurrent density is related to external quantum efficiency that is the collective measure of three key efficiencies of light harvesting, charge separation and charge collection. Although three efficiencies are equally important, light harvesting efficiency is crucial. In this talk, technologies based on nano-engineering will be introduced to have high light harvesting efficiency in DSSC
