New Fraunhofer Solar Cell Stringer Uses Adhesives For 2% Boost

An R&D team at Fraunhofer ISE has unveiled a new solar cell stringing machine that can boost cell performance 2% by using electrically conductive adhesives to fix solar cells to a foil substrate in a shingled pattern. The process reduces the number of manufacturing steps that soldering a connective ribbon would require, and imparts more efficient cell performance in several incremental ways.

Sunfolding’s Pneumatic Solar Tracker Builds 60 Megawatt Pipeline

Maverick pneumatic solar tracker maker Sunfolding has amassed a pipeline of 60 megawatts for the first quarter of 2019, following its 2018 commercial rollout, says Matthew Schneider, the vice president of product at the San Francisco-based company. Sunfolding also is supplying its first delivery contract for a utility-scale photovoltaic array, a 39 MW project in California, using the company’s motor-less T29 single-axis design.
