Solar electronics leaders Enphase and SolarEdge post strong Q4 and massive 2019
The leaders in solar module-level power electronics are profitable and making enormous jumps in revenue. All signs point to a strong 2020 for residential solar — which could keep the momentum going.
The inner workings of a lithium battery
An international group of scientists has developed a method to track the microscopic processes at work in lithium batteries. Employing a ‘virtual unrolling’ model developed for ancient manuscripts too sensitive to be opened, the group peeked inside the layers of a commercial battery to gain a better understanding of the processes at work and the degradation mechanisms affecting them.
Silicon heterojunction solar cell hits 23.5% efficiency with new hole-selective contact
Researchers from Switzerland’s École Polytechnique Fédérale de Lausanne have used molybdenum oxide as the hole-selective contact in a heterojuction silicon cell. The scientists claim the compound can compete with traditional contacts despite a lower level of optimization.
Job moves: Engie fires CEO, plus Enphase, Sunrun, Sol Systems, Nautilus, Sage Energy
Executive and boardroom moves in solar, storage, project development, cleantech, utilities and venture capital.
Italian PV panels destined for recycling were instead smuggled to Syria and Africa
Illegally re-badged panels were sold to Senegal, Burkina Faso, Nigeria, Morocco, Mauritania, Turkey and Syria. Italian authorities found 60 tons of panels.
French solar institute and Enel announce 24.63% efficiency for heterojunction solar cell
The efficiency of the cell, made with a standard M2 wafer, was raised 0.7% by using an improved busbar-free screen printing metallization based on heterojunction processes developed with manufacturing equipment provided by Swiss specialist Meyer Burger.
Coronavirus could cause solar panel price spike
The coronavirus outbreak in China could raise solar module prices in the near term as manufacturers have already begun experiencing wafer and solar glass shortages. Production rates are also being affected by an extended new year holiday introduced by the authorities as a measure to deal with the virus, and the requirement workers from infected areas quarantine themselves for two weeks.
Germany added almost 4 GW of PV in 2019
The German network operator reported approximately 339 MW of new solar in December. New installations for 2019 exceeded new capacity additions in 2018 by more than 1 GW.
Perovskite/silicon tandem solar cells approaching 30% efficiency in lab
Scientists at the Helmholtz Zentrum Berlin have taken back the world efficiency record for a perovskite/silicon tandem solar cell, achieving 29.15% with a device measuring 1cm². The record has been confirmed by Fraunhofer ISE, and according to HZB, this means that the 30% efficiency mark is within reach.
Qatar’s 800 MW tender draws world record solar power price of $0.01567/kWh
The winning consortium was formed by French oil giant Total and Japanese conglomerate Marubeni Corp.
