US Customs solar exclusions might be ‘de facto ban on Chinese polysilicon’
Longi solar modules made of Tongwei polysilicon have been excluded from entry to the U.S.
Solar module prices, auction volumes, and the outlook for capacity addition
Timely scale-up in tendering activity and moderation in solar PV cell and module prices, if sustained, would support improvement in capacity addition in the renewable energy sector.
Italian startup offers solar kits packed in barrels
Italy’s Barrel claims that solar kits packed in barrels are ideal for remote areas and conflict zones. Its standard packages consist of 6 kW solar modules, 5.6 kW single-phase hybrid inverters, and 3.55 kWh lithium batteries.
Fully printed carbon electrode perovskite solar cell achieves 19.2% efficiency
German scientists have fabricated a carbon electrode perovskite solar cell with a hole-transporting bilayer made of organic semiconductors instead of a conventional hole transport layer. They claim this approach improves the device’s fill factor and open-circuit voltage.
Tongwei plans 16 GW PV cell factory
Tongwei says it will build a new 16 GW solar cell factory in Meishan City, China’s Sichuan province.
Using existing fences as near-zero-cost racking solution for PV deployment
American researchers are proposing to use steel zip ties to attach solar modules to fences in animal farms as a low-cost racking solution for agrivoltaic applications. They found the proposed approach is technically and economically viable, provided careful wind load tests are conducted on the fences.
Indoor perovskite PV solar cells with 32.0% efficiency
Scientists in Thailand built an indoor perovskite solar cell with low-cost carbon electrode architecture. The manufacturing process is based on antisolvent deposition and vacuum thermal annealing (VTA) and reportedly results in higher perovskite film quality.
Big module makers in China call for wafer standards
Trina Solar, JinkoSolar, JA Solar, Longi, Risen, Canadian Solar, Tongwei, Chint, and Das Solar have issued a joint statement demanding the standardization of wafer sizes.
China polysilicon prices hold steady amid rebound talk
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
New study finds growing inequality in metal footprints of renewable power value chains
A US-Chinese research team has investigated the flow of iron, copper, aluminum, and other precious metals from source to end-use destination in the renewable energy infrastructure value chain. It found significant imbalances that can be attributed to the continuous outsourcing of metal demand for the renewable power sector to developing economies.
