To achieve useful current and voltage, photovoltaic modules have to be “broken up” into small segments that are series-interconnected. The “break lines”, also called “dead area”, should be as small as possible, since they are not available anymore for energy conversion. By applying an optimized laser patterning process, CHEOPS managed to keep this dead area width as small as 400 μm on perovskite solar cells.
CHEOPS will continue to improve the laser patterning process in order to achieve a ratio between active and aperture area of 95–97 %.
