Solar cell and electronic device

Abstract

The invention provides a solar cell. The solar cell comprises a front electrode, a functional layer and a back electrode, the front electrode is an electrode on one side of a light receiving surface, the front electrode comprises a high-conductivity area and a low-conductivity area which are adjacent to each other, or the back electrode comprises the high-conductivity area and the low-conductivity area which are adjacent to each other. According to the solar cell, the front electrode and / or the back electrode are / is designed in different regions, and the conductivity of one conductive region is designed to be higher than that of the other conductive region, so that thin film sheet resistance loss caused by large-range transverse non-uniform transfer of light current can be effectively avoided, and the photoelectric conversion efficiency of the cell is improved; and according to different requirements of different regions in different application scenes, material selection can be flexibly performed in different regions, and the comprehensive performance of the battery is improved. The invention also provides an electronic device comprising the solar cell.

Description

technical field

[0001] The embodiments of the present application relate to the field of energy technology, and in particular, to a solar cell and an electronic device thereof. Background technique

[0002] In recent years, smart glasses consisting of conventional sunglasses or optical glasses combined with Bluetooth, audio and convenient human-computer interaction have become more and more popular among consumers. However, with the excavation and integration of more diversified functions of smart glasses, the contradiction between smart glasses functions and battery life has become more prominent, increasing consumers' anxiety about battery life.

[0003] Thin-film solar cells have excellent characteristics such as high efficiency, thinness, flexibility, transparency and color adjustment, and are the best choice for power supply devices for wearable smart devices such as smart glasses. For an area of ​​20-30cm 2 If the single lens of smart glasses can obtain tens to hundr...
