Researchers in Switzerland have set an efficiency record for a new type of solar cell that rivals satellite-grade solar panels at a fraction of the cost.
A team at the Ecole Polytechnique Fédérale de Lausanne (EPFL), together with the Swiss Center for Electronics and Microtechnology (CSEM), achieved an efficiency rate of 30.02 per cent with the triple-junction device, beating the previous record of 27.1 per cent.
