Photoelectric conversion device

Abstract

This invention relates to a photoelectric conversion device, comprising a wafer, a transparent band differential efficiency color enhancement layer, an encapsulation layer assembly, and a surface cover lens assembly. The wafer has a light-receiving side and a backlight side. The encapsulation layer assembly has a front encapsulation layer and a rear encapsulation layer. The surface cover lens assembly has a front surface cover lens and a rear surface cover lens. The transparent band differential efficiency color enhancement layer is disposed on the light-receiving side of the wafer. The front encapsulation layer of the encapsulation layer assembly is fixed on the transparent band differential efficiency color enhancement layer, and the rear encapsulation layer is fixed on the backlight side of the wafer. The front surface cover lens of the surface cover lens assembly is fixed on the front encapsulation layer, and the rear surface cover lens is fixed on the rear encapsulation layer. The transparent band differential efficiency color enhancement layer improves the color display and saturation of light refraction and has a color reflection effect when illuminated by a light source, thereby achieving excellent structural functionality and photoelectric efficiency.
