A team of researchers from Manchester University claims to have identified the dominant process causing light-induced degradation in silicon solar cells. The process, termed “trap-assisted auger recombination”, arises from a defect in the bulk of the silicon material which lies dormant until exposed to sunlight.

The two Chinese companies will acquire 30% shares in each other’s respective wafer and silicon businesses and plan to purchase at least 75% of each other’s future output, as part of a complex mutual investment arrangement announced ahead of the SNEC PV Power Expo 2019.

At The smarter E Europe trade show, held in Munich in May, pv magazine was invited for another iteration of its Quality Roundtable events. Experts from manufacturing, project planning, finance and testing took the stage to inform the crowd on quality issues with modules, cables and inverters.

JinkoSolar today announced that it has set a new efficiency record for a monocrystalline PERC PV cell at 24.38%, and produced a module that achieved 469.3 W power in testing conducted by TÜV Rheinland. The Chinese module manufacturer also equalled a record claimed just last week by Trina Solar, of 24.58% conversion efficiency for an n-type monocrystalline cell.

While market experts suggest solid-state battery technology will not play a significant role in the storage industry until 2025, one company may be leading the race. Blue Solutions, electrical energy storage award winner at The smarter E Europe in Munich, Germany, says it has developed the only commercialized solid-state lithium battery. pv magazine caught up with the company around the European trade show to discuss its award-winning technology and unique position in the market.

A Russian research team believes that the addition of rare-earth ions into the structure of photonic nanoparticles could help to increase the efficiency of industrial solar cells to 25–30%. However, they also said that further research is necessary.

At the Smarter E Europe, held in Munich this month, pv magazine hosted another Future PV Roundtable to discuss the possibilities of subsidy free solar projects. In all market segments solutions are at hand and representatives across the industry shared their insights with us.

Although the nation’s PV industry has recently established new landmarks, warnings have been sounded about the immediate outlook for the sector.

The race is on to process applications for central payments across the world’s biggest solar market, particularly as qualifying projects must reportedly be grid connected this year. The final electricity price will be a major competitive factor considered by the Beijing authorities.

Some 56 bids were submitted for the fourth round of the RenovAr program for large scale renewables. Projects will be selected on July 22. With this procurement the Argentinian government wants to allocate a total of 350 MW of solar and wind generation capacity, with a 10 MW size limit per project.
