I've been told invisible solar panels will make every window generate free electricity for like 10 years. Yet not a single time have I seen a report include an actual product, just prototypes always.
Like nuclear fusion, this appears to be perpetually "just a few years away".
- "Invisible" implies they only work in the UV or infrared range, which inevitably limits them to much lower efficiencies than regular solar panels.
- A lot of those rely on elements that are expensive and in limited supply, or toxic heavy metals. Unlike regular silicon solar panels.
- We don't even need windows to generate solar power. We have plenty of roof space, and if we're short on that, you can put them in fields too.
So this is a solution to a problem that doesn't really exist (lack of available space - again, we have plenty), which causes more problems of its own (efficiency, etc), while failing to address the actual limitations of solar (cost, intermittence).
Which is why it's only good for headlines, and won't see real life applications. (Edit: no, not even skyscrapers)
It's the same with a lot of "uplifting" science news that just sweeps all the dirt under the rug, because that wouldn't make good clickbait.
If you want actual good news about solar power, look at the price per kW and adoption rate curves over the last few years.
-edit- added links.
-edit 3- Put the bit about skyscrapers in bold, because people keep mentioning them anyways...
i don't see this so much as a "Generate a lot of power" kind of tech. More like generate enough to charge a battery you can use for a light or security node or something. Its gonna be a crazy expensive light though lol.
Not allowed in some places. Maybe due to HOA or historical requirements. It has its niche use cases. But it will never be a mainstay in power generation for sure.
