COOKING UP A 'LIGHT SPONGE': DSC AND DYESOL TECHNOLOGY

摘要

According to Dyesol, dye solar cell technology (DSC) can be best characterised as 'artifical photosynthesis.' As a plant leaf uses sunlight absorbed by chlorophyll to convert CO_2 and water into food energy, the DSC replaces the leaf structure with a porous titania nano-structure and the chlorophyll with a long-life dye. The energy circuit is completed by a redox couple.An effective DSC was first successfully demonstrated in Switzerland in the late 1980s after years of efforts to replicate the principle of natural photosynthesis for solar energy generation.
