High efficiency solar cells on germanium can also be applied to terrestrial photovoltaics. Here, cells are integrated in a concentrator system based on refractive or reflective optics.
Under concentrated sunlight, the most advanced solar cells on germanium have a conversion efficiency of over 40%, paving the way for cost effective and sustainable energy generation. Umicore produces concentrated photovoltaic (CPV) wafers in different diameters up to 150mm in production quantities.
