The Fraunhofer Institute for Solar Energy Systems ISE has achieved an efficiency of 25.1% on a both sides-contacted silicon solar cell. In addition to increasing efficiencies, the TOPCon technology is said to simplify manufacturing processes.
Swiss PECVD tool developer INDEOtec has sold one of its Octopus II PECVD tools to France’s IPVF (Institut Photovoltaique d’Ile-de-France). The Octopus II tool is a deposition platform for high efficiency PV cell production, such as HJT concepts.
German researchers have applied the approach used by invisibility cloak research to direct sunlight around busbars and metallization fingers to potentially increase PV cell and module efficiency. The research was
