China startup makes large, flexible solar panels in industry first
Japanese-developed perovskite technology goes into mass production

TOKYO -- A Chinese startup this month became the first in the world to mass-produce large, bendable perovskite solar panels, based on technology initially developed by researchers in Japan.

DaZheng (Jiangsu) Micro-Nano Technologies invested 80 million yuan ($11.8 million) to build a production line with an annual capacity of 10 megawatts in Jiangsu Province. The 40 cm by 60 cm panels will be cut into smaller pieces and shipped to smartphone and tablet makers in China.

DaZheng will invest 200 million yuan in 2023 to expand its annual production capacity to 100 MW, Chief Technology Officer Li Xin told Nikkei.

Perovskite solar cells were pioneered in 2009 by Toin University of Yokohama engineering professor Tsutomu Miyasaka and his team. Although these lightweight cells have a power conversion efficiency of around 10% -- about half that of silicon cells -- they can be incorporated into windows, walls and more.

Smaller perovskite cells have been mass-produced before, but DaZheng is the first to do so for large panels. While these cells currently cost three times as much to make as conventional silicon cells, this could potentially be brought down to half at a higher scale.

The technology is seen as a candidate to win a Nobel Prize. There is hope that the cells can eventually be applied by a printer, or be painted onto entire cars.

The global market for perovskite solar cells is projected to expand to over $2 billion by 2027 with annual growth averaging about 29% starting in 2022, according to Indian research company Astute Analytica.

Japanese companies like Kyocera and Sharp were once leading players in solar cells but downsized operations over the years as price competition ate into profits. Chinese and South Korean players now control much of the market. Japanese companies have little capacity to make new investments, allowing China to take the lead in large-scale perovskite panels.

DaZheng's Li studied under Miyasaka and continued his research after returning to China. Miyasaka also provided development support.

Can be incorporated into vehicles sunroof/moonroof and windows as a secondary charging.

As compared to Regen, solar panel is worse off.

Look at energy recovery of Taycan which is on 800v archi

Anything China make, there will be excess, can wait and see. And also price will gradually comes down cos so many people will rush in to do. Haha

oh... So next time zinc roof can also fix solar panel? That's good news!  :grin:

U staying in which kampung ??🤣🤣

Would be good if it can be incorporated into large awnings and parasols so that can install lights or fans beneath them or for storage for later use at night

Storage needs big battery

Can stick on car roof to charge EVs? 😁

Car wash a few times all flower flower how 🤔..  but im sure someone will find some flexible gorilla glass by then

Can lah ……. At the base of the parasols ( need weighted down)…… batteries also quite slim ( just for lighting purpose can lah ) not as in running AC’s of course

Depends on battery size.

I am looking at Tesla Powerwall https://www.tesla.com/powerwall

That might be used to power the house at night.
