Core Viewpoint - The article emphasizes the significant growth potential of Back Contact (BC) battery technology in the photovoltaic industry, highlighting its high technical barriers and economic viability, with major manufacturers planning substantial capacity expansions from 2024 to 2027 [1][2][4]. Capacity Expansion - Major manufacturers are expected to add 40-65 GW/year of BC capacity from 2024 to 2027, with existing TOPCon capacity of 780 GW undergoing upgrades for greater output [1][4]. - The planned capacity for leading domestic BC manufacturers includes Longi Green Energy at 107.5 GW, with incremental additions projected for the years 2024 to 2027 [5]. Economic Viability - The cost of mature production capacity is around 0.69 CNY/W, while BC technology offers a premium of 0.05-0.1 CNY/W, indicating a favorable economic outlook [2][4]. - The estimated market space for BC laser equipment is projected to reach 4.75 billion CNY by 2027, while the market for BC coating equipment is expected to reach 6.5 billion CNY [4]. Technological Advancements - BC technology requires significant upgrades in laser and coating equipment, with laser device value increasing from 4-20 million CNY/GW in TOPCon to 50-60 million CNY/GW in BC [6][7]. - LPCVD coating technology is anticipated to see increased adoption due to its suitability for BC applications, with its penetration rate expected to rise significantly [8]. Investment Opportunities - The article suggests that BC technology will create investment opportunities in laser and coating equipment, as leading manufacturers are likely to upgrade their capacities in a counter-cyclical manner [10].
