Flexible BIPV panel with 410 W output from Italy
Developed by cleantech company Verditek, the flexible module has a 20.1% efficiency and a weight of 4.9kg. It can bend up to 35% using standard 160µ-thick crystalline cells.
China power crisis hits Indian solar projects
After the ravages of Covid-19, electricity shortages in China have now raised costs for its solar manufacturers, with knock-on effects for developers in India too, again highlighting the dangers of relying on a single solar supply chain.
Cambridge scientists develop Zinc-ion battery that stores solar energy
U.K. researchers have developed a battery with a photocathode made of vanadium dioxide, which is used to harvest light and store zinc ions and zinc oxide as a charge transport layer. The device showed an efficiency of around 1.2% and capacity retention of around 73% after 500 cycles.
When oversized is really the right size
U.S. researchers have concluded that wind and solar generation resources that were sized at 1.5 times along with three hours of energy storage would meet all but 200 hours of demand scattered throughout any given year.
Should I include a battery with my home solar project? Part 2: Costs and savings
An increasing share of residential solar arrays now include energy storage batteries. In part one of this two-part series, pv magazine reviewed the backup power features of batteries. In this part, costs, benefits and timing are evaluated.
Scaling up perovskite-silicon tandem solar cell performance
Scientists in Germany investigated various routes to optimizing cell design for perovskite-silicon tandem products. Beyond the perovskite layer itself, they note several other areas that should be optimized for tandem cells, taking silicon heterojunction processing as a starting point. The research identifies several routes to cut costs in cell production, including a significant reduction in indium consumption.
How to clean PV systems covered by volcano ashes
Spanish company Multisistemas E2 has explained how PV systems affected by the volcano eruption in the Canary Islands are currently being cleaned.
Germany has installed 4 GW of PV so far this year
In June alone, new PV additions totaled 406 MW. Feed-in tariffs were reduced by another 1.4%.
Solar Frontier abandons thin-film, launches 250 W monocrystalline panel
The Japanese manufacturer decided to close its CIS module production in October and has now launched its first 250 W monocrystalline product for the residential market.
