Researchers in Korea have proposed a new design for dividing and bonding which is said to provide higher efficiency from fewer fingers. The number of fingers optimized for division into five cells was 128 and for three, 171. Five offer power conversion efficiency of 17.346% and three 16.855%.
A list compiled by a British price comparison website draws upon data from German company Statista which shows clean energy – including hydro – made up 12.74% of the nation’s power mix at the end of September.
The Chinese government will extend duties on U.S. and South Korean polysilicon for another five years from today despite committing to buy $200 billion more American goods and services in the trade deal signed on Wednesday. Poly manufacturer REC Silicon says it expects polysilicon to form part of that trade agreement.
Some 15 countries are likely to be able to lay claim to the status of being members of solar’s “gigawatt club” in 2019, according to conservative projections from BloombergNEF. Nonetheless, PV suppliers, developers and service providers are always on the lookout for new pockets of growth. To kick off 2020, pv magazine’s global team of correspondents and editors have highlighted 10 “fast-growing” solar markets to evaluate where the opportunities, and potential risks, lie.
The country’s Ministry of Trade, Industry and Energy (MOTIE) has provided new market share figures for the domestic PV sector that contradict recent media claims that Chinese manufacturers have been aggressively ramping up their local presence at the expense of Korean module makers. The government has also confirmed plans to prioritize PV projects made with low-carbon, high-efficiency modules.
By this time next year we may be able to wave goodbye to that old chestnut about renewables endangering security of supply. Elsewhere, the price of lithium – and the products it goes into – could go either way after tanking this year.
Battery innovations started to come thick and fast this quarter as the hunt for alternatives to lithium-ion intensified and the latest slew of solar tenders indicated the relentless pressure on solar power generation costs was showing no sign of abating.
Intersolar Europe is always a key date in the solar calendar but this year’s show had it all, including three panel-smuggling arrests. Elsewhere, wafers were getting bigger, efficiency records were tumbling and new technologies were emerging. There was also more news on the solar car ports fad and Hanwha’s ongoing legal tussle.
The first part of pv magazine’s review of 2019 considers Q1, when solar early adopter Italy offered an optimistic start to the year by fleshing out its plans for PV but uncertainty still clouded the world’s biggest solar market. The potential for household solar installations to rocket the world over – helped by ever cheaper panels – prompted strategic decisions in the inverter market and analyst expectations were confounded as the cobalt and lithium price plummeted, bringing the EV revolution a big step nearer.
Researchers from Saudi Arabia’s King Abdullah University of Science and Technology claim to have developed a highly performant organic PV cell using tungsten disulfide flakes a few atoms thick. The stability of the device, however, is still to be evaluated.
