Japan Bets On Super Thin, Film-Like Panels to Reclaim Solar Leadership At Expo 2025
Thin film was a thing 20 years ago. I remember a mate recommending it when we were buying Sharp panels, $650 for an 80 Watter. So now it's back but I doubt it's a real game changer. In this day of maximum Lies it will simply be a ramp-up to sell stock in some company. Something a percentage of the Dull Cow herd will put money into, just in case.
$this->bbcode_second_pass_quote('', 'A')t Expo 2025 in Osaka, Japan is using an unexpected location—a bus terminal—to highlight its latest innovation: ultrathin “perovskite” solar panels, according to Nikkei. More than 250 of these flexible, lightweight panels line the curved roof of the Yumeshima Transportation Terminal 1. Japan hopes this film-like solar tech will not only boost domestic renewable energy and reduce reliance on China, but also help it lead the next generation of solar innovation.
"It's like killing three birds with one stone," said Takayuki Taenaka of Japan's Ministry of Economy, Trade and Industry (METI). Perovskite solar cells, discovered in 2009, are made from layers of chemicals just millimeters thick. Though still in early development, they rival traditional silicon-based panels in efficiency while being 20 times thinner and 10 times lighter, allowing installation on walls, rooftops, and even windows—places unsuitable for heavy panels.
"We believe this technology has the potential to beat the conventional silicon-based solar panels in terms of power generation efficiency," said Futoshi Kamiwaki, president of Sekisui Solarfilm, which developed the panels showcased at the Expo.
Japan, with limited flat land, leads major nations in solar capacity per km² but is running out of space. Installing perovskite cells on buildings could turn cities into vertical solar farms, helping Tokyo meet its 2040 goal: 29% of power from solar, up from under 10% today.

Dear oh Dear, don't they layer on the bullshit.
Lets face it, if they were of any value the Chinese would have copied the tech and be pumping them out by now. I'm not suggesting they don't work! And they no doubt have a niche usage, But I can't see thin plastic competing with toughened glass. (think mild hail, birds landing, regular washing) So a few local governments will put them on bus shelters but for the public solar is a big expense, one where you expect a 20 to 25 year return. I have yet to see any "plastic" that old still sitting happily in the sun.
Tip: If you employ those solar garden lights or security lights, and can't find what you want with a glass solar panel, cut small squares of glass and affix them, otherwise in 2 years you'll be out there with a Brillo pad scrubbing off the white oxidized plastic layer. Glass blocks the UV and that's the killer here. Ordinary glass blocks about 97% of UVB rays
We're 17 years past the peak now and the 3rd World is going hungry and dark. We'll be next, we're well on the way in fact.
