Fraunhofer ISE unveils rotary printing technique for heterojunction solar cell metallization

Researchers at the German research institute have found that indirect gravure printing for metallization of silicon heterojunction solar cells reduces silver consumption and cycle times to below 0.5 seconds per cell, while still enabling conversion efficiencies of up to 20.7%.

Sinovoltaics charts growth of PV manufacturing in India

The latest supply chain report from the Hong Kong-based technical compliance and quality assurance company covers India, providing information about current and planned capacity at 116 manufacturing plants.

Sinovoltaics updates financial stability ranking of PV module manufacturers

The latest Sinovoltaics financial stability report ranking lists Tainergy, Eterbright, First Solar, Era Solar, and TSEC as the top five module makers. There was a slight reshuffling in the top ten, and seven new manufacturers were added to the ranking.

New water circulation tech promises lower PERC solar cell manufacturing costs

A German team developed models to illustrate water-saving potential in PERC silicon solar cell manufacturing based on a circular approach and commercially available technology. In the case of a 5 GW fab, water savings of up to 79% and wastewater discharge reductions up to 84% could be achieved, a “significant” improvement compared to a reference scenario.
