Abstract

The invention relates to a photoelectric conversion element which is applicable to converting a light ray into a light current. The photoelectric conversion element comprises a light converting layer, a top conducting layer and a bottom conducting layer. The light converting layer is provided with a bottom plane, a top flat face relative to the bottom flat face and a light incident side face connected between the bottom flat face and the top flat face, wherein the included angle between the bottom flat face and the light incident side face is theta, and theta is not less than 64 DEG and not more than 79 DEG. The top conducting layer is arranged above the top flat face of the light converting layer, and the bottom conducting layer is arranged below the bottom flat face of the light converting layer.

Description

technical field [0001] The present invention relates to a photoelectric conversion element, and in particular to a vertical type photoelectric conversion element. Background technique [0002] In recent years, photoelectric conversion elements such as solar cells and photosensors have been widely used in human living environments. With the issue of environmental protection and energy saving, solar cells have become the most potential green alternative energy, and light sensors have been applied in flat panel displays. Through the light sensor, the flat panel display can detect the intensity of external light to adjust the brightness of the display. In addition, the light sensor enables the flat panel display to have a touch function and / or a scanning function, making the flat panel display more multifunctional. [0003] On the substrate, the photoelectric conversion elements can be roughly divided into two types according to their structures: one is a horizontal photoelect...
