High resistance transparent oxide cdte
WebHigh-resistance transparent (HRT) layers have been used as a buffer layer between the transparent conducting oxide (TCO) and the CdS layer to help maintain CdS/CdTe device performance when thin CdS films are used or there is a high density of pinholes. Several HRT materials have been used as a buffer layer, including undoped SnO 2, TiO 2
