Cue Lemmy comments complaining about this being RND and people can’t buy 35% efficiency panels from Costco this weekend.
To put it into perspective, perovskite solar cells have had multiple headlines a month as a “breakthrough“ and “just around the corner” for more than ten years. I think those that follow this tech are just getting a little disappointment fatigue. Awesome tech though - I just hope they can make it stable enough to last in real world conditions soon.
Just saying that, with energy and medical scientific advancements, you’re often looking at decade long lead times before something is available for the masses. And humans famously suck at contextualizing things over long periods of time.
It’s normal to hear about R&D that is a decade or more from commercialization. It often takes a long time to secure investment for consumer applications, invent new mass manufacturing processes for a new technology, etc.
And I completely agree with you, it’s always going to take a while.
I just remember years ago when it was promising a 50% increase in efficiency, but then regular panels caught up and achieved that anyway. This game of cat and mouse has been running for Elon Musk’s Full Self Driving level timelines.
I believed the hype and in ~2020 decided to wait to add a 2nd array until perovskite panels were released “early next year”, and I’m still waiting 3 years later. I hear they will be produced early next year, so that’s something to look forward to.
