Method for enhancing the conversion efficiency of CdSe-quantum dot sensitized solar cells

摘要

CdSe-quantum dots are formed on a TiO2 patterned layer by chemical deposition from a solution of aminotriacetic acid/cadmium (NTA/Cd) and sodium selenosulfate. CdSe-quantum dots are useful as sensitizers for solar cells. The conversion efficiency of light of light power to electric power is enhanced by adjusting the ratio of potassium aminotriacetate to cadmium (NTA/Cd) as well as the chemical bath deposition (CBD) temperature and time.
