Analyst revises up zero-emission vehicle forecast after bumper year
A report published by BloombergNEF for the COP26 climate change summit has listed global commitments by cities, states, provinces and nations to end the sale of new fossil-fueled vehicles but, with 2035 estimated as the cut-off date for zero-emission roads by mid century, policymakers need to be more ambitious.
The state of EU renewables – Solar cell plans encouraging but heat pump market could go the same way as European PV did
The European Commission has published its second annual assessment of the competitiveness of the EU’s renewable energy technology industries, and it had a warning for policymakers about the trade balance trend being experienced by heat pump makers.
Isomer passivation for a 21.4% efficient perovskite module
An international team of scientists trialled a new approach to passivating defects in perovskite solar cells. Using a tailored arrangement of atoms, the team was able to overcome challenges related to the formation of a two-dimensional perovskite layer on top of the active cell material, and reach 21.4% conversion efficiency for a 26cm² active area, which they claim as a record for a perovskite device of this size.
