China’s New Energy Sector Faces Challenges in Advanced Solar Cell Production Technology
On May 23, 2025, a report highlighted the challenges faced by China’s new energy sector, specifically regarding advanced solar cell production technology. The report came from a collaboration between a national enterprise and a prestigious university, focusing on innovations in solar energy generation.
Recently, there has been significant progress in the stability of solar cell production, which is crucial for enhancing the technology’s application in various sectors. This report was presented in the journal Science, showcasing the advancements achieved in the laboratory.
According to the authors, the latest technology, which aims to improve solar energy production, has been demonstrated to be effective in achieving a steady increase in solar cell efficiency. The research team expressed that the solar cells developed are the third generation of this technology, known for their high efficiency and lightweight characteristics, ensuring reliable performance even under low-light conditions.
The core component of these solar cells is a perovskite layer, primarily created using a solution process involving perovskite precursors. Previous common manufacturing techniques struggled with precision control of crystallization and uniformity, which significantly impacted the efficiency of the solar cells.
At the University of Jiangsu, supported by strategies from Jiangsu University of Technology and Engineering, the team has developed a three-dimensional layered flow field technology, which addresses issues related to the large area of perovskite solar cells.
“The three-dimensional layered flow field technology allows for precise control over the crystallization of perovskite layers, which enhances stability and efficiency,” said one of the researchers. Through computational fluid dynamics simulations, the technology has shown to effectively manage the crystallization parameters, maintaining the stability of the perovskite layer below 3 micrometers.
In comparison to traditional methods, the three-dimensional layered flow field technology reduces surface defects and enhances crystallization quality, achieving a 90% reduction in defect density.
Moreover, with the application of this new technology, perovskite solar cells are projected to have a degradation rate of less than 10% over a 10-year usage period, meeting the requirements for long-term application.
These advancements are being implemented at a plant located in Jiangsu, which has a production capacity of 500 megawatts for perovskite solar cells. This facility has achieved a maximum efficiency of 29%, with peak output efficiency reaching 31.9% during optimal conditions.
Experts from the University of California emphasized that this new technology demonstrates significant improvements in stability, production efficiency, and adaptability, indicating that perovskite solar cell technology has reached a foundational level of production standards.
Overall, the advancements in this field reflect a promising future for solar energy generation, with the potential to enhance energy efficiency and sustainability in various applications.
