Recently developed, highly stable perovskite materials show promise for use in concentrator photovoltaics where the illumination intensity far exceeds standard test conditions. Here, we demonstrate solar cell devices employing different perovskite absorber layers featuring balanced charge generation and extraction characteristics at high light intensities greater than 10 suns. Using a mixed cesium-formamidinium perovskite, we are able to achieve over 18% PCE at 1 sun and 16% PCE at 13 suns with negligable performance loss after several hours of high intensity light soaking.
