Adjusted Colorful Amorphous Slicon Thin Film Solar Cells by a Multilayer Film Design

Abstract

An adjusted color of amorphous silicon thin film solar cells is illustrated by using a multilayer film design. The multilayer film consists of silver (Ag) and gallium doped Zinc oxide (GZO), which serves as an adjusted color reflection (ACR) multilayer film. The color can be adjusted with wide range from dark blue to blue red colors when the GZO thickness increases from 50 to 150 nm. The color adjusted by the ACR multilayer film is in good agreement with the reflectance response of the multilayer. The influence of the ACR multilayer film on the solar cell performance is discussed.
