Eggplants grow 50% more under solar panels
French specialist Sun’Agri unveiled the agronomic results on a crop of eggplant grown in a greenhouse commissioned in the Lot-et-Garonne in September, 2020.
US startup begins producing 40%-efficient thermophotovoltaic cells
Antora Energy says its new 2 MW factory will make thermophotovoltaic cells for thermal storage applications. The cells are based on III-V semiconductors and reportedly have a heat-to-electricity conversion efficiency of more than 40%.
The fastest energy change in history
Solar and wind are being installed at a rate that is three times faster than all other new electricity sources combined. This offers compelling market-based evidence that PV and wind are now the most competitive and practical methods for deploying new generating capacity.
New way to calculate LCoE of perovskite solar
Italian researchers have analyzed different ways to assess the levelized cost of energy (LCoE) of perovskite solar cells and modules. They said a common approach should soon be defined to increase the market maturity of the tech.
Only5mins! – The steeplechase of perovskite solar
The potential of perovskite solar cells and modules is still held back by issues such as stability and efficiency losses when scaling up from cell to module. But Annalisa Bruno, a scientist at Singapore’s Nanyang Technological University, says most of these challenges could be overcome in the near future, with this technology extending from building-integrated PV to conventional solar projects.
Passive solar module cooling tech based on paraffin wax
Egyptian researchers have used paraffin wax as a phase-change material (PCM) to reduce the operating temperatures of PV modules. They have found that the material improves power yield by more than 15%, compared to a reference module without cooling.
Vertical PV for clean energy and crop production
Researchers and project developers throughout the world are increasingly looking at agrivoltaic installations with vertically oriented solar panels.
Assessing vibrations in solar modules due to robot cleaning
Qatari researchers have looked at the degree to which cleaning robots could threaten the physical integrity of solar panels. They found that cleaning machines have a very minimal impact and that modules of similar sizes tend to exhibit roughly the same amount of vibration.
Spray passivation to reduce losses in TOPCon, HJT cell-to-module process
Chinese researchers have developed a new passivation technique for shingled solar panels based on tunnel oxide passivated contacts (TOPCon) or heterojunction (HJT) tech. It reduces recombination losses in the cell-to-module process and reportedly increases open-circuit voltage, fill factor, and efficiency.
Hanwha Q Cells unveils updated modules for Australian rooftop market
Hanwha Q Cells has launched the latest generation of its Q.MAXX solar panel series for the Australian residential market. It says the power class has been increased by up to 15 Wp from previous iterations.
