Significant carbon footprint advantage, reducing carbon emissions by 0.1 billion tons per year

As the world attaches increasing importance to climate issues and reaches a consensus on addressing climate change, countries have successively defined the goals of "carbon peaking" and "carbon neutrality". The 27 EU countries, the UK, Canada and other countries have all decided to achieve carbon neutrality by 2050. The Chinese government has also announced that it will peak carbon emissions by 2030 and achieve carbon neutrality by 2060. However, as a major manufacturing country, China has a typical high-carbon energy structure. Compared with European and American countries that have already completed industrialization, such planning has a tight schedule and a long way to go.

The dual-carbon action will promote the world economy to shift from fossil energy to a new energy structure dominated by wind and solar, and gradually move from resource dependence in the past to technology dependence. For the achievement of my country's dual carbon goals, clean energy development, efficient energy utilization, and zero carbon emissions Technology, etc. are necessary paths. Therefore, more and more domestic companies are beginning to pay attention to low-carbon manufacturing and implement the environmentally friendly development concept of reducing carbon footprints. The photovoltaic industry is also committed to producing green solar products and clean electricity in an efficient and energy-saving way.

Many solar cell technologies that have attracted industry attention today, such as PERC, HJT, TOPCon, perovskite, IBC, etc., each have their own strengths. However, in terms of "low-carbon manufacturing" and "energy saving", HJT heterojunction high-efficiency solar cell technology More skilled. Compared with PERC products, HJT battery modules have absolute advantages in carbon footprint performance.

01 HJT——Using low-carbon manufacturing technology to achieve zero-carbon photovoltaic energy

According to data calculations from the Institute of Electrical Engineering of the Chinese Academy of Sciences, Huasheng R&D Center, TV Süd, and CTC (China National Inspection and Quarantine), the carbon footprint of HJT modules can be reduced to 397g CO/W by the end of 2022, while the carbon footprint of PERC modules currently on the market The value is 600g CO/W. It can be estimated that the carbon footprint of HJT modules will be 200g CO/W less than that of PERC modules. When thinner silicon wafers are used (130μm reduced to 120μm or even lower), the low-carbon advantages of HJT battery modules will be more prominent. .

According to predictions from industry organizations, around 2030, the world’s newly installed photovoltaic capacity will exceed 500GW/year. If all HJT components are used, compared with PERC components, carbon emissions will be reduced by 100 million tons per year. According to calculations by investment institutions, my country's carbon emissions will peak at approximately 10.8 billion tons in 2030. It can be seen that the 100 million tons of carbon emissions reduced by HJT will account for 1% of my country's total carbon emissions that year. From the economic benefit assessment, based on the current price of European carbon trading of 70 euros/ton, HJT’s annual reduction in carbon emissions will be worth 7 billion euros, about 50 billion RMB.
