Ternary CuIn7Se11 : towards ultra-thin layered photodetectors and photovoltaic devices

Abstract

A few-layered ternary Cu-In-Se compound is synthesized, the photoconductivity is measured, and 2D photovoltaic devices are fabricated. Few-layered CuIn7 Se11 has a strong photoresponse and the potential to serve as the active medium in ultra-thin photovoltaic devices.

Keywords: copper-indium-selenide; layered materials; photodetectors; photovoltaics.
