Photovoltaic technology is an important engine to boost the green transformation of energy under the goal of carbon peaking and carbon neutrality. Perovskite solar cell is considered one of the most promising solar cell technologies in the future due to their advantages of high conversion efficiency, fast iteration speed, short process flow, low raw material cost, and low energy consumption. Perovskite solar cell is still in the early stage of industrialization with the formula, equipment, and technology still under iterative development. Once the mass production process of large-area modules is mature, perovskite batteries will go on a different commercial path from crystalline silicon with lower cost, and richer application scenarios.
As the global leader in the industrialization of perovskite in solar power modules, GCL Photoelectric Materials is far ahead in the conversion efficiency of large-area preparation of perovskite and the progress of a 100MW mass production line.
Leading the Industrialization Process of Perovskite
The 100MW Mass Production Line for Modules with the World’s Largest Area Has Been Built
GCL Photoelectric Materials has accumulated rich industrialization experience in the stage of large-area module efficiency and pilot test line and successfully enlarged it onto a 100MW large-area module production line, leading the world in the two key indicators of finished module efficiency and stability.
In September 2021, GCL Photoelectric Materials built the world’s first 100MW mass production line, with a module size of 1m × 2m. At present, GCL Photoelectric Materials’ 100MW mass production line is in the stage of process development and equipment transformation, with the conversion efficiency of finished modules steadily improving. It is expected that the conversion efficiency will exceed 16% by the end of this year and 18% by the end of 2023, becoming the first 100MW production line in the world to run through mass production.
The conversion efficiency of 18% is of great significance to perovskite industrialization. At present, the actual efficiency of 1m × 2m crystalline silicon modules on the market is about 20%. Due to the different circuit structure from crystalline silicon modules, the power generation of perovskite modules with the same efficiency is 5% higher than that of crystalline silicon on average. If GCL Photoelectric Materials’ 100MW production line were able to mass produce 18%-efficiency large-size modules, with the lower manufacturing cost of perovskite modules, it would significantly strengthen the competitiveness of perovskite modules in the photovoltaic market.
In terms of stability, most advanced laboratories have been able to continuously operate perovskite modules for at least 1,000 hours without attenuation. The service life of GCL Photoelectric Materials 100MW finished products is expected to exceed 25 years. On June 7th, 2022, the 1m × 2m perovskite modules produced by the company passed the hail test, which is a strong piece of evidence for the tolerance of large-area modules in severe weather.
With Continuous Independent Innovation, GCL Photoelectric Materials Leads the World in Large-Area Preparation Efficiency
The conversion efficiency of perovskite is the industry’s most concerned index. Currently, the conversion efficiency of a single junction of perovskite can reach 26% in the laboratory, the theoretical conversion efficiency can reach 33%, and the theoretical efficiency of tandem perovskite cells can reach 45%, which is much higher than that of the crystalline silicon battery. However, this index is only of practical industrial significance when it is on a module with a large enough area for commercialization.
Large-area preparation is one of the biggest challenges for perovskite mass production. Small-sized modules are of little economic value. Therefore, perovskite components need to be larger to reduce costs for mass production. However, the large-area preparation of perovskite films faces such problems as non-uniformity and increased resistivity, sharply reducing the conversion efficiency. Manufacturers must systematically redesign and commission the material formula, coating, crystallization, laser, and more to ensure that the module efficiency will not be impaired in large-area preparation.
As early as 2019, GCL Photoelectric Materials took the lead in completing 15.31% efficiency certification of 45cm × 65cm (2925cm2) large-area perovskite module.
With continuous technological innovation advantages, GCL Photoelectric Materials has made breakthroughs in the conversion efficiency of large-area modules. At present, the 1m × 2m perovskite module produced by GCL Photoelectric Materials is the world’s largest perovskite module, with the conversion efficiency of finished modules being nearly 16%, which is expected to exceed 18% by the end of 2023.
Accelerate the Green Transformation of Global Energy
To Become a Globally Competitive Perovskite Module Manufacturer
Driven by the goal of carbon peaking and carbon neutrality, governments worldwide have accelerated the transition to green energy. New energy technologies represented by photovoltaics have ushered in a golden stage of development, with the installed capacity of new photovoltaics globally rising rapidly every year. According to the survey report of the International Energy Agency (IEA), the global installed capacity of new photovoltaics is expected to be 190GW in 2022, reaching a record high. However, due to the cyclical adjustment of the photovoltaic industry and the rising cost of silicon materials, among other factors, the actual installed photovoltaic capacity in the world has fallen short of expectations since 2021.
In this context, perovskite battery, as a new generation of solar cell technology, has a broad commercial prospect. Compared with traditional crystalline silicon batteries, the perovskite battery preparation process is shorter with lower energy consumption, boasting obvious cost advantages. The highest process temperature in the whole process of perovskite module preparation is lower than 150 Celsius degrees, with the unit energy consumption being only one-tenth of that of the crystalline silicon module and the investment per unit capacity is only about half of the crystalline silicon. At the same time, because of its excellent characteristics, such as being lightweight, thin, flexible, and translucent, perovskite photovoltaic modules have more applications than crystalline silicon batteries. They can be used in photovoltaic panels for ground power stations, BIPV curtain walls, electric vehicles, and more.
The advantages of high efficiency, low cost, low energy consumption, and rich application scenarios make perovskite batteries one of the most promising photovoltaic technologies with the goal of carbon peaking and carbon neutrality. According to the report of Precedence Research, an international market research organization, the global perovskite solar cell market was about USD 600 million in 2021, which will jump to USD 7.2 billion by 2030, with a compound annual growth rate of 31.8%.
