The photovoltaic power generation industry develops rapidly and crystalline silicon solar cells gain broad market prospects.

Solar cells are the core components of photovoltaic power generation systems. They are semiconductor sheets with light and electrical conversion properties that can directly convert solar radiation energy into direct current. Solar cells can be divided into two types: crystalline silicon solar cells and amorphous silicon solar cells. Crystalline silicon solar cells are the mainstream product in the market.

The production process of crystalline silicon solar cells is relatively complex and requires processes such as cleaning and texturing, diffusion, etching, dry oxygen growth mask, screen printing, and rapid sintering. Crystalline silicon solar cell production technologies include HJT cell technology, PERC cell technology, N-type bifacial cell technology (TOP Con) and conventional aluminum back field cell technology (Al-BSF), etc. PERC battery technology is based on Al-BSF battery technology and uses the back passivation process to increase the open circuit voltage of the battery and greatly reduce light loss. At present, PERC cell technology has become the mainstream production technology of crystalline silicon solar cells in my country due to its advantages such as high maturity and simple operation.

In recent years, as environmental pollution and energy crisis problems have continued to intensify, the proportion of clean energy consumption has continued to grow. As the most widely used clean energy, solar energy is favored by the global consumer market. Against this background, the prosperity of the crystalline silicon solar cell industry continues to increase, and the total global crystalline silicon solar cell production capacity will exceed 260.0GW in 2021.

Crystalline silicon solar cells are mainly used in the field of photovoltaic power generation. According to statistics from the China Photovoltaic Industry Association, in the first two quarters of 2022, my country’s newly installed photovoltaic power generation capacity reached 30.9GW, a year-on-year increase of 137.4%, ranking first in the world. Benefiting from the rapid development of the photovoltaic power generation industry, my country’s crystalline silicon solar cell output continues to grow. According to the “2022-2027 Crystalline Silicon Solar Cell Industry Market In-depth Research and Investment Prospect Forecast Analysis Report released by the Industrial Research Center It shows that my country’s crystalline silicon solar cell output will reach 167.2GW in 2021, a year-on-year increase of 14.2%.

The main manufacturers of crystalline silicon solar cells in my country include Jiangsu Trina Solar, Chengdu Tongwei Solar, Jiangxi Jinko Power, Shanghai Aixu New Energy, Xi’an LONGi Silicon Materials, etc. The above companies account for nearly 50.0% of my country’s crystalline silicon solar cell market. % share. Chengdu Tongwei Solar is a brand of Tongwei Group, focusing on the R&D and production of core solar power products. Its crystalline silicon solar cell production capacity, output and shipments have long ranked first in the world. According to Tongwei Group’s annual report, the company’s solar cells, components and related businesses achieved revenue of 24.90 billion yuan in 2021.

Industry analysts said that driven by positive factors such as national policy support, my country’s photovoltaic power generation installed capacity continues to grow, which will provide a great opportunity for our country. Provide driving support for the development of the crystalline silicon solar cell industry. Driven by leading enterprises, the industrial structure of my country’s crystalline silicon solar cells has been further optimized, and the overall competitiveness of local enterprises has been significantly enhanced.
