Plus there is news this week of a green hydrogen tie-up in India, plans for another German production facility, and of new hydrogen transport networks for Switzerland and the U.S.
Last week’s announcement Oxford PV wants to wind up its “exclusive cooperation” with Meyer Burger after the fit out of its 100 MW German factory points to a potential divergence in strategies. And with Meyer Burger considering legal action in response, it could result in a messy, disruptive separation.
Meyer Burger claims machines to produce perovskite tandem solar cells are still missing at Oxford PV’s manufacturing plant in Germany’s Brandenburg an der Havel. Despite this, Oxford PV terminated the cooperation with the turnkey machine supplier in a surprise move last week. The Swiss technology group, which now produces its own heterojunction solar cells and modules in Germany, is now considering legal action.
The latest global PV industry outlook published by trade group SolarPower Europe, has indicated tight supply of the solar panel raw material is expected to persist this year but the trade body said it would be unlikely to drive further price rises.
Scientists in Switzerland discovered that certain types of phosphate salt react with lead only in the presence of moisture, to form non-water-soluble phosphates. Incorporating these salts into the architecture of a lead-based perovskite solar cell could greatly reduce the risk of lead seeping into the environment should the cells be damaged, without incurring significant costs or negatively affecting the cell’s performance.
A 10 kW PV system has been feeding electricity into the Swiss power network since 1982. A research team has investigated the performance of the array’s first 35 years of life and has found that solar modules can target – at least in temperate climates – service lifetimes of 35 years, and that the bill of materials matters, a lot!
Scientists in Switzerland demonstrated a new type of nanoscale doping for perovskite solar cells. By both improving stability and reducing the chance of the cells leaking any toxic lead into the environment, the discovery addresses two of the largest remaining challenges to the development of the promising class of cell materials.
Swiss researchers sought for the first time to replace phenylethylammonium (PEA) with benzodithiophene (BDT) in cations for perovskite cells. The latter showed improved stability and ensured a power conversion efficiency that was 1% higher than that of its counterpart.
Swiss manufacturer Leclanché will build the new battery modules at its manufacturing facility in Yverdon-Les-Bains. These products can be used for transport applications such as marine, commercial vehicle, and railway.
