Abstract

The invention provides a method for manufacturing a solar power generation assembly. The method successively comprises the following steps of: providing a silicon substrate having opposite first and second surfaces; etching grooves formed in the silicon substrate; forming a plurality of first solar cell units in the plurality of grooves, wherein the top surfaces of the solar cell units are flush with the first surface; forming a patterned first transparent conductive layer on the first surface; forming a plurality of second solar cell units on the first surface, wherein the second solar cell units and the first solar cell units are arranged in a staggered way in the lateral direction; and connecting the first transparent conductive layer to the top electrode of a first solar cell unit and the bottom electrode of a second solar cell unit to form a plurality of first solar cell packs.

Description

Technical field [0001] The invention relates to the field of new energy, in particular to a manufacturing method of solar power generation components. Background technique [0002] With the continuous development of mankind, energy consumption is increasing, making the related technology of solar modules a hot issue that the whole society pays close attention to. As for the solar module itself, its conversion efficiency to sunlight and its stability are directly related to the solar cell manufacturing process and solar structure. In the prior art, solar cells are mostly laid out in the same plane to form large-area solar cell panels for subsequent packaging. However, the solar cell panels arranged in this way have low light utilization efficiency and are not easy to lock the light. How to improve the conversion efficiency of solar cells is a key point that needs to be improved. Summary of the invention [0003] Based on solving the above-mentioned problems, the present invention...
