Abstract

The invention discloses a cylindrical solar cell assembly which comprises cylindrical solar cells and a packaging backboard. Each cylindrical solar cell comprises a column-shaped substrate, and a bottom electrode, a bottom transparent conducting layer, a function layer, a top transparent conducting layer and a grid electrode layer which are successively formed on the substrate, first grooves are formed in the bottom electrode and the bottom transparent conducting layer, the function layer includes second grooves, the top transparent conducting layer and the grid electrode layer include third grooves, and the top transparent conducting layer comprises first and second transparent conducting layers. The backboard includes a reflection surface of a waveform composed of semicircles, and each semicircle corresponds to one cylindrical solar cell. The cylindrical solar cell assembly can convert sunlight in each direction into the electric energy.

Description

technical field [0001] The invention relates to a solar cell, in particular to a cylindrical solar cell component. Background technique [0002] Since solar energy is a kind of green and environment-friendly energy, it is less destructive to the ecological environment than other energy sources, so more and more countries encourage the development of solar cells. Among solar cells, silicon-based solar cells can be divided into crystalline silicon solar cells and amorphous silicon thin-film solar cells. Among them, crystalline silicon solar cells have high photoelectric conversion efficiency and are often used outdoors or in large-area settings. . However, the manufacturing cost of crystalline silicon solar cells is relatively high. Therefore, in some applications with small areas or low requirements for cell conversion efficiency, you can choose to use amorphous silicon thin film solar cells to meet the use requirements and save production costs. [0003] At present, solar ...
