Effects of He ion and electron beam irradiation on a CdTe solar cell dosimeter in a substrate configuration

Abstract

In this work, the effects of He ion and electron beam irradiations to the substrate-type CdTe solar cells, which was suitable for the detection of alpha and beta radiation, were investigated. He ion irradiation revealed that the induced current proportionally increased with the increase of He ion current and that it was possible to detect alpha radiation using the substrate-type CdTe solar cell dosimeter. Next, the electron irradiation effects were investigated. The induced current proportional to the electron flux was also observed, and the sensitivity depended on the electron energy. In addition, the degradation of substrate-type CdTe solar cell dosimeter by electron beam irradiation was investigated. No significant degradation in short-circuit current was observed by the electron irradiation of 3×1016 cm-2 at 200 keV and 1×1016 cm-2 at 400 keV. This result suggests that the substrate-type CdTe solar cell dosimeter is sufficiently resistant to electron irradiation.

In2S3 Thin Films via Open‐Air Chemical Vapor Deposition Using Indium‐Diethyldithiocarbamate: Deposition and Characterization

“…[29] Herein, we propose a low-cost and facile method for the deposition of In 2 S 3 thin films: open-air chemical vapor deposition (CVD). [30,31] We successfully prepared In 2 S 3 thin films using indium-diethyldithiocarbamate (In-DDTC) as a single precursor and investigated the mechanism of In 2 S 3 deposition using the open-air CVD method. Additionally, we determined the crystal structure, optical properties, and electrical characteristics of the film.…”
