‘Turbocharging’ silicon PV: MIT scientists scratch the surface of singlet exciton fission
Scientists at the Massachusetts Institute of Technology have developed a device they say could “turbocharge” a single-junction silicon PV cell, pushing the technology beyond its theoretical limit to efficiencies of 35% and higher.
Sorbitol admixture to passivation layer increases HJT conversion efficiency
The race to the theoretical maximum conversion efficiency continues and with new lab results in, it appears a big leap forward may have been achieved at Leibniz University Hannover.
Ideematec banks new investment worth millions for business expansion
The solar tracker supplier is benefiting from a steadily growing PV market and has inked a deal with ABN AMRO Energy Transition Funds for new capital to expand its operations.
Unlocking lithium metal’s stored potential
Several new concepts in lithium-ion storage technology have the potential to greatly the increase the energy capacity of batteries. Among them are lithium metal anodes, which could potentially increase energy density by more than 50%. With a newly optimized electrolyte, scientists at the University of California, San Diego have taken another step toward making the idea a commercial reality.

Battery scientists make a cracking observation
Scientists at the Georgia Institute of Technology in the U.S. used x-ray imaging to observe cracks forming in a solid state lithium battery, a discovery they say changes the understanding of performance of solid state batteries and which could lead to more durable systems.
The second Democratic debate: The return of the Green New Deal
The first debate, featuring the two front-runners for the Democratic nomination, showed clear and growing divisions within the Democratic Party on climate policy as much as everything else.
Product recall: SMA calls in MLPE over rapid shutdown problem
The inverter maker conducted tests and found the branded SMA TS4-R-F-42 could not always supply the rapid shutdown function called for by a new U.S. safety standard when applied in commercial and industrial systems featuring its inverter tech.
Amtech nears final solar exit with SoLayTec sale
The Arizona-based equipment maker is sticking to its guns by withdrawing from the PV market after sales wobbled in China last year. With most of the big players having rediscovered their thirst for expansion, however, it appears a curious strategy.
Los Angeles seeks record sub-two cent solar power price
