Pronounced “peh-ruhv-skite,” these solar cells have tantalizing potential. Theoretically more powerful, cheaper and less energy intensive to produce than existing technology, they’re also thinner, lighter and — crucially — flexible, opening up a variety of new possible sources of clean power generation, from car rooftops to billboards.
The problem is, perovskite cells are a bit like a finely tuned race car. They work great in controlled environments, but don’t do so well when it’s time to go off-road. Combinations of moisture, heat and sunlight – hardly rare conditions in locations best suited for solar panels — can warp their unique crystalline molecular structure, leading to rapid degradation and a loss of power.
DaZheng Micro Nano Technology Co., a startup founded in eastern China in 2018 that’s raising funds to build the world’s first mass-production plant for the technology.
DaZheng has sold more than 100 megawatts worth of perovskite panels to customers in China, the US and and Australia, according to the company. It’s now among at least 14 Chinese entities seeking to add perovskite manufacturing lines. Ma’s firm aims to build a factory to produce 100 megawatts of panels a year, and has plans to lift annual capacity to 1,000 megawatts as early as 2025.
The Jiangsu-based company claims its perovskite modules can retain more than 90% of their original efficiency after 15 years of use, which, if true, would resolve the main barrier the technology faces to enter the mass market — a decline in generation capacity as the panels age. To improve performance, DaZheng has taken steps including adjustments to the cell encapsulation process, according to Ma.
The benefit is that perovskite products are lighter and bendable, meaning that they can be used in places regular panels can’t be installed, according to Ma.
Incumbent technology is unlikely to lose “market dominance in the next 10 years,” said Hou Yi, assistant professor at the Solar Energy Research Institute of Singapore. “It is also important to remember that perovskite technology has emerged only in the past decade.”
As long as perovskite can solve degradation problems the technology should eventually enter the mainstream, Li Zhenguo, founder of Longi Green Energy Technology Co., the world’s largest solar manufacturer, said in a September speech.
Even so, DaZheng’s mass-produced perovskite modules generate less electricity than regular panels. They’re also currently about five or six times more expensive, though Ma says his company’s products could fall to half the price of existing silicon-based panels once production is scaled up.
Some funding is already flowing into the sector. A perovskite unit of renewable giant GCL Technology Holdings Ltd. raised 500 million yuan ($72 million) last December, and investors put 360 million yuan into Microquanta Semiconductor in 2021.
For bulls like Ma, the technology is likely to co-exist alongside silicon for some time — and then ultimately replace the currently preferred format. “We should give perovskite enough tolerance and time,” he said.
