A long-lasting aluminum battery
Scientists in the U.S. developed an aluminum battery that demonstrates better than 99.5% reversibility, and could offer “up to 10,000 error-free cycles”. By incorporating a substrate of carbon fibers into the anode design, the group gained better control over chemical bonds that form as the battery charges, leading to greatly improved performance.
Trina became world’s third biggest panel supplier in 2020
The Chinese giant overhauled JA Solar by moving almost 16 GW worth of modules, with the 600 W-plus, 210mm-wafer-based Vertex range it launched last year having already sold 10 GW of units.
Key energy proposals from the US administration and Congress
It’s been a busy two months since Joe Biden became U.S. president. Here are highlights of key initiatives on the energy and clean-tech fronts.
Reducing solar project risk for extreme weather
We will discuss how rigorously tested modules and correctly engineered system designs create a major opportunity for U.S. utility-scale developers to lower project risk and LCOE.
Bright future for long-duration storage, but costs must fall
U.S. researchers have discovered that long-duration energy storage technologies could make the decarbonization of the electricity system more affordable and reliable.
MIT scientists reveal method to identify stable perovskites
U.S. researchers are using a data fusion approach to identify the most stable perovskites for PV cells. Their machine-learning method combines perovskite test results with first-principles physical modeling to identify the best candidates.
Tigo launches optimizer for high-power modules
The IEC certified product has a maximum wattage of 700 W, a maximum current of 15 A, and a maximum voltage of 80 V.
Battery costs have fallen 97% since 1991, claim MIT researchers
Academics reviewed the historic price development of lithium-ion batteries and found the accepted model does not accurately reflect the full cost decline and technological improvement which has taken place. With more data points to compare, the team found batteries had improved even more than previously assumed.
YouTube – a proven marketing platform to expand solar businesses
YouTube videos are becoming a vital part of consumers’ solar-buying journey, providing a unique opportunity for solar marketers. Marketing pro Rich Feola offers insights on how to use videos to boost your solar company.
US government wants to cut solar costs by 60% in 10 years
The US Energy Department set a goal of achieving 2 cents/kWh by 2030, and announced an initial $128 million in funding to support technology development.
