Perovskite cells of lesser sizes have been mass-produced before, but DaZheng is the first for large panels.
DaZheng Micro-Nano Technologies Deliver Massive Flexible Perovskite Solar Panels
Based on technology initially created by academics in Japan, a Chinese business this month has become the first in the world to mass-produce massive, flexible perovskite solar panels.
Perovskite cells of smaller sizes had previously been mass-produced, but DaZheng is the first to do it for large panels. While the cost to produce these cells is now three times that of traditional silicon cells, the price might be reduced to half on a bigger scale.
Jiangsu Province's DaZheng (Jiangsu) Micro-Nano Technologies committed RMB 80 million (USD 11.8 million) to construct a manufacturing line with a 10-megawatt annual capacity. The 40 by 60-centimeter panels will be divided into smaller parts and sent to Chinese manufacturers of smartphones and tablets.
According to chief technology officer Li Xin, DaZheng would spend RMB 200 million (29.6 million USD) in 2023 to increase its annual production capacity to 100 MW.
Tsutomu Miyasaka, an engineering professor at the Toin University of Yokohama, and his group invented perovskite solar cells in 2009. These small, lightweight cells may be used in windows, walls, and other structures despite having a power conversion efficiency of about 10%, roughly half that of silicon cells.
According to the Indian research firm Astute Analytica, the perovskite solar cell industry is anticipated to rise to more than USD 2 billion by 2027, with annual growth averaging over 29% beginning in 2022.
The technology is seen as a candidate to win a Nobel Prize. There is anticipation that the cells may ultimately be able to be painted on complete automobiles or applied by a printer.
Perovskites Could Revolutionize Solar Cells? Here's Why
Flexible, textured solar panels made from Perovskites are possible. These lightweight materials would be as efficient as silicon-based photovoltaics. However, perovskite-based solar cells must overcome significant difficulties to be commercially feasible.
Metal oxide perovskites are a form of perovskite used in catalysis, energy storage, and conversions, such as fuel cells and metal-air batteries. Lead halide perovskites have been a focus of study for over a decade, says Tonio Buonassisi, professor of mechanical engineering at MIT and director of the Photovoltaics Research Laboratory.
It also tolerates structural flaws well, he says. It can work well even with many defects and impurities, unlike silicon.
Researchers have developed a machine-learning technique to help find viable perovskite compositions. This new technique might lead to speedier alternative development, adds co-author Buonassisi.
Perovskites continue to show promise, and numerous businesses are ramping up for commercial production, but durability remains a challenge. Perovskites solar panels decay quicker than silicon after 25 years. Initial samples lasted just a few hours, then weeks or months, but modern formulations survive a few years, sufficient for several purposes.
Most studies concentrate on encapsulating perovskite to protect it from air and moisture. Others are exploring the degradation processes to create more resilient formulations or therapies. Autocatalysis is primarily responsible for the deterioration, researchers say.
Perovskite development has been promising. In only a few years, it has attained efficiency equivalent to cadmium telluride (CdTe), which has been around longer. The progress on perovskites has been 100 to 1,000 times quicker than on CdTe.
