heterojunction

For the production of its heterojunction modules, the Russian manufacturer will cooperate with the German PV engineering provider for the supply of stringers and adhesive technology. To this end, Hevel has ordered new stringer systems and layup from Teamtechnik.

For solar to survive in a world without feed-in tariffs, further innovation focused on cost reduction is necessary. In this white paper, scientists from Swiss equipment supplier Meyer Burger argue that high efficiency cell concepts, and in particular heterojunction, will be among the best technologies solar can bet on to achieve this.

The Switzerland-headquartered company has secured a contract for the delivery of its SmartWire solar module production line to an undisclosed customer in Southeast Asia.

Researchers from Helmholtz-Zentrum Berlin (HZB) and Oxford PV have presented a new record perovskite tandem solar cell, with a 25.2% conversion efficiency, independently verified by Fraunhofer ISE. Bernd Stannowski, from HZB presented the results this week at the World Conference on Photovoltaic Energy Conversion (WCPEC-7) in Hawaii.

Crystalline silicon tandem cell structures show great promise in delivering efficiencies beyond the limits of conventional c-Si. Swiss researchers claim to have gone beyond 25% with a c-Si-perovskite tandem cell structure, using what they claim is a competitive production process.

Panasonic has been improving the cost and durability of heterojunction cells for years. Meyer Burger’s smartwire connections could replace three-busbar technology and drive further advances

By proving inductively coupled plasma can be used for HJT-cell production, the research institute and corporate partner will now work on ways to find cost-effective production methods with the aim of making a GW scale roll out of HJT cells viable

Solartech Universal plans to expand its current 80 MW/year capacity by 180 MW/year. The company is seeking a facility in South Florida.

Japanese electronics giant, Sharp has announced the achievement of a 25.09% conversion efficiency, from a cell utilizing both heterojunction (HJT) and back contact technology. The measurement has been validated by Japan Electrical Safety & Environment Technology Laboratories (JET).

Scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have created a solar cell using colloidal quantum dots, which achieved 13.4% conversion efficiency – a new world record for this emerging technology.
