Sinovoltaics tracks emerging PV manufacturing hubs in Europe, North America
Sinovoltaics is studying the changes in the supply chains in manufacturing hubs in Europe and North America to determine site capacity, current and planned, for dozens of manufacturers. The results are being published in free reports.
PV-driven water splitting system with solar-to-hydrogen efficiency of 9.8%
Scientists in Korea have built a green hydrogen system prototype that embeds a PV generation unit based on photoanodes made of perosvksite solar cells. The device purportedly achieved a solar-to-hydrogen efficiency of 9.8% for a device with a size of 0.25 cm2, and 8.5% for a system measuring 123.2 cm2.
New method to find right tilt angle for PV systems located in high-latitude, cold regions
A group of researchers from Sweden has developed a new model to find the optimal tilt angle in PV installations located at high latitudes. The new approach takes into account, among other factors, the effect of transmittance change based on snow.
First attempt to build selenium-silicon tandem solar cells
Scientists in Denmark attempted for the first time to build a selenium-silicon tandem solar cell and found the device was immediately able to deliver a remarkable open-circuit voltage. Despite its current low efficiency levels, the new cell concept promises to reach efficiencies over 40%, according to its creators.
