method of producing high purity CuInSe2 Thin Films Prepared for solar cells and from the CuInSe2 Thin Films

摘要

This invention is a copper thin film on a substrate by depositing a copper precursor having an asymmetric structure with a chemical vapor deposition method After manufacture, the copper thin film is formed on a substrate of indium-deposited continuously asymmetric precursor comprising selenium under mild temperature and time conditions, copper: indium: selenium, the proportion of 1: 1: single-phase high purity to meet the CuInSe 2 ₂ relates to a process for the production and from the prepared CuInSe ₂ thin film of the thin film. ; the production method of the present invention using an asymmetric precursor chemical vapor by depositing by vapor deposition, in a predetermined relatively low temperature and shorter time than the prior art with no change in composition, and without introduction of impurities in high purity CuInSe ₂ can be prepared a thin film, made of highly pure CuInSe ₂ thin film can be applied usefully in the light absorbing film layer, quantum dots or the LED thin-film solar cell field. Furthermore, the invention of the high purity of CuInSe ₂ thin-film solar cells are ultra-thin light-absorbing layer (Extremely Thin Absorber layer Solar cells, ETA Solar Cells) field to take you there.
