Companies say perovskite tandem solar cells are only a few years from bringing record efficiencies to a solar project near you.
In Swift Solar’s lab, more than a dozen pairs of elbow-length rubber gloves hover horizontally in midair, inflated like arms.
Carbon dioxide electroreduction in acidic environments has been suboptimal. Here, the authors addressed this issue by designing a gas diffusion electrode with a special metal structure, which achieves efficient electroreduction while conducting a systematic investigation of the underlying mechanism.
We are already living in the era of the fourth industrial revolution, but in the near future we will be facing another one that could really change everything. We are talking about the revolution of humanoid robots — versatile, intelligent and dexterous machines that can not only help, but also replace humans in tight places. In this video, we’ll tell you about the top 10 newest and most advanced humanoid robots in the world, and what technologies will make them truly versatile! Onward to a brighter future)

Artificial intelligence can accelerate the process of finding and testing new materials, and now researchers have used that ability to develop a battery that is less dependent on the costly mineral lithium.
Lithium-ion batteries power many devices that we use every day as well as electric vehicles. They would also be a necessary part of a green electric grid, as batteries are required to store renewable energy from wind turbines and solar panels. But lithium is expensive and mining it damages the environment. Finding a replacement for this crucial metal could be costly and time-consuming, requiring researchers to develop and test millions of candidates over the course of years. Using AI, Nathan Baker at Microsoft and his colleagues accomplished the task in months. They designed and built a battery that uses up to 70 per cent less lithium than some competing designs.
LG is already one of the most prolific EV battery manufacturers in the US, but it wants to build the devices that charge them, too. The company just opened just opened its first EV charger manufacturing facility in the US, a 59,000 square foot plant in in Fort Worth, Texas capable of manufacturing 10,000 units per year.
The company has already started to assemble 11kW home-style chargers there and will begin producing 175kW fast chargers in the first half of 2024. It plans to built 350kW ultra-fast chargers at some point this year designed for “commercial travel and long-distance transportation,” LG wrote.
The Korean company said it chose Texas as it had existing facilities there and because the state offers “excellent logistics and transportation networks and is home to major operations for companies in industries ranging from automobile manufacturing to finance” (GM, Toyota and Tesla all have vehicle assembly plants in the state).
Scientists have unveiled a roadmap for bringing perovskite/silicon tandem solar cells to market, paving the way for a future powered by abundant, inexpensive clean energy in Saudi Arabia and the world.
The authors of the article, published in Science, include Prof. Stefaan De Wolf and his research team at King Abdullah University of Science (KAUST) and Technology Solar Center. The team is working on improving solar efficiency to meet Saudi Arabia’ solar targets.
Perovskite/silicon tandem technology combines the strengths of two materials— perovskite’s efficient light absorption and silicon’s long-term stability—to achieve record-breaking efficiency. In 2023, the De Wolf laboratory reported two world records for power conversion efficiency, with five achieved globally in the same year, showing rapid progress in perovskite/silicon tandem technology.
University of Michigan researchers have found that large additives could be the secret to making stable and long-lasting perovskite solar cells.
Researchers from the University of Michigan have found that large additives appear to prevent perovskite semiconductors from degrading quickly.

The KES batteries play a crucial role in reducing the curtailment of renewable energy by 69%, allowing Hawaiian Electric to integrate 10% more new utility-scale renewables than previously projected. Additionally, the project is estimated to save customers money, reducing electric bills by an average of $0.28 per month over a 20-year contract life.
The specifications of the KES plant include 135 MW / 540 MWH of capacity and energy, 50 MW / 25 MWH of additional ‘fast frequency response’ for grid stability, ‘virtual inertia’ to mimic the power-smoothing function of a spinning turbine, and ‘black start’ capabilities for grid recovery during blackouts.

Zero-emissions long-distance aviation is absolutely possible… Provided you’re not in a hurry. Solar Airship One will take 20 days to fly all the way around the equator, some 40,000 km (~25,000 miles), in a single zero-emissions hop.
The 151-m (495-ft)-long airship will have its entire upper surface covered in solar film – some 4,800 square meters (51,700 sq ft) of it, or about nine-tenths of an NFL football field for those of you who prefer the standard units.

Solar panels are already an affordable energy solution since they generate enough power over their lifetimes to pay for themselves and then some. However, they do take some investment up front, and some people (and homeowners associations) dislike the way they look.
So what if you could get that power to make electricity from sunlight without having to install solar panels? That’s the beauty of solar paint, as reported by Solar Action Alliance.
The idea behind solar paint (aka photovoltaic paint) is simple: It’d be like ordinary paint but with billions of light-sensitive particles mixed in, as Understand Solar notes.
