New solar cells hit 30% efficiency and still work after 1,000 hours of power
The team developed a chemical-hardness strategy to control crystal growth.

Chinese scientists have pushed perovskite tandem solar cells past the critical 30 percent efficiency mark after developing a new way to control how the materials crystallize during manufacturing.
The research team was led by Ge Ziyi, PhD, and Liu Chang, PhD, from the Ningbo Institute of Materials Technology and Engineering (NIMTE), under the Chinese Academy of Sciences (CAS). The team hit a certified power conversion efficiency of 30.3 percent in rigid all-perovskite tandem solar cells, and 28 percent in flexible versions.
They believe that the achievement can speed up the development of lightweight, high-efficiency solar technologies that are far cheaper and easier to manufacture than traditional silicon-based panels.
The findings provide a pathway to simultaneously improve efficiency and durability in both rigid and flexible devices, thereby advancing the development of lightweight, scalable photovoltaic technologies, the scientists pointed out...more

The study has been published in the journal Nature Nanotechnology.
Chemical hardness engineering synchronizes crystallization in perovskite tandems
Abstract
All-perovskite tandem solar cells are constrained by asynchronous crystallization in multicomponent perovskites, which produces vertical compositional gradients, structural inhomogeneity and excessive non-radiative recombination. These effects arise from mismatched coordination and crystallization kinetics among mixed halides and Pb2+/Sn2+ cations...
The governments own data rebuts Trumps claims about wind and solar prices
As of late 2025 and early 2026, President Donald Trump has consistently criticized solar and wind energy, calling them a "scam of the century" and "farmer destroying," often blaming them for rising electricity costs, according to AP News and Facebook/Washington Post. These claims are frequently deemed inaccurate, as experts state renewables are often the cheapest energy source, and analysts attribute price hikes to infrastructure issues...
And some call solar/wind "JUNK". LOL

(38,437 posts)Most perovskites are lead based, offering the world an opportunity to match leaded gasoline and coal for uncontrolled lead distribution in the environment.
Of course there has never been an antinuke who gives a shit about the toxicology of fossil fuels, which is why some of them come around here pushing coal based hydrogen in China with a dishonest representation that hydrogen there is "green." (Chinese scientists have not invented a way to label flowing electrons by source, since doing so is impossible, nor have they demonstrated a means to prevent the daily occurrence of something called "night."
I often consider that the distribution of lead, a neurotoxin, ay account for the intellectual level of antinukes, but I'm only guessing at that.
