Perovskite: a new force in the next generation of photovoltaics, gradually becoming a rising trend (with report)

Report Guide

As the PERC efficiency of the current mainstream technology in the photovoltaic market is gradually approaching the ceiling, the development of HJT, TOPCon and xBC technologies is in full swing. As a new force in the next generation of photovoltaics, perovskite solar cells will continue to improve their photoelectric conversion efficiency, which will become the top priority of the future layout of photovoltaic manufacturers. Heavy.

Investment Points

Perovskites (PSCs): One of the most promising next-generation optoelectronic materials with excellent properties and wide applications

Perovskite is a crystalline material with the general molecular formula ABX3, in the shape of an octahedron, with high photoelectric conversion efficiency, and is widely used in photovoltaics, LEDs and other fields. Perovskite solar cells (PSCs) are solar cells that use perovskite structural materials as light-absorbing materials. Perovskite solar cells can also further improve the photoelectric conversion efficiency by stacking with HJT, which is the key development direction of future industrialization.

Core highlights: high efficiency, low cost advantages, stability, environmental protection, and large area preparation problems are breaking through

High efficiency: The theoretical conversion efficiency of single-junction PSCs can reach 31%, which is 29.4% higher than the limit efficiency of crystalline silicon cells. PSCs have good tandem cell matching with HJT, and can manufacture tandem cells with a theoretical efficiency of 43%.

Low cost: Compared with traditional crystalline silicon (silicon materials, silicon wafers, cells, modules), the industrial chain links of PSCs are greatly simplified, and the value of a single link is highly concentrated, which is expected to greatly reduce the manufacturing cost of photovoltaic modules.

Mass production: The main problems in the industrialization process of PSCs are to solve the problems of stability, large-scale preparation and environmental protection. Benefiting from the designability of perovskite materials, the industrialization process continues to advance.

Market space: It is estimated that the equipment market space will exceed 80 billion in 2030; BIPV will bring 100 billion space

Application side: Perovskite has the characteristics of light weight, small thickness, large flexibility, and translucency. It is a star material in the field of BIPV and mobile power generation for electric vehicles in the future. We predict that the potential market size of BIPV will reach 121 billion yuan in 2025. Perovskite has natural adaptation advantages and is expected to take the lead in opening the market in the field of BIPV.

Equipment side: The main processes for the preparation of perovskite solar cells are coating and PVD. The production process is much simpler than that of crystalline silicon, and it is currently in the stage of equipment process verification. We estimate that the market space for perovskite solar cell equipment in 2030 will be about 80.5 billion yuan.

Industrialization process: The domestic pilot of the R&D side continues to make breakthroughs, and the progress of the industrial side is accelerated.

Academic side: China’s perovskite solar cell R&D team has made concerted efforts to explore the most competitive and cost-effective technical route through the combination of production and research. The number of patent applications accounted for 68% of the world’s total.

Industry side: Local perovskite equipment manufacturers have placed orders first, and some of them have been successfully delivered. The efficiency of local perovskite solar cell manufacturers has continued to break through, financing is progressing smoothly, and pilot lines have been deployed.
