Optical properties of electrochemically deposited CdTe films

Abstract
The optical properties of electrochemically deposited CdTe films were investigated. The index of refraction and the absorption coefficients in the 450–850‐nm range were measured for as‐deposited n‐type films and converted p‐type films. It was found that the converted p‐type films had higher optical absorption coefficients near the band edge than that of the n type. This change can be attributed to defect absorption. The absorption data yielded information concerning the band structure of the electrodeposited CdTe.
