The development of solar cells and modules continues at a rapid pace. Yield must be increased and production costs must go down. ECN conducted a test with a back-contact module, and will present the results at the European PV Solar Energy Conference. “As opposed to a conventional solar panel, the contacts of a back-contact module are interconnected at the back of the cell, both positive and negative,” said Ian Bennett, a senior researcher at ECN. “The advantage is that shade is not a problem...
