CHEOPS assessed a new production process for bigger (5×5 cm2) perovskite solar cells. The process significantly improves the cells’ performance and spatial uniformity – both is key to the scale-up of the technology. To increase the photovoltaic performance of perovskite solar cells, CHEOPS researchers conducted several experiments to assess the effect of a thinner electron … Read more
On 25th-26th June 2018, CHEOPS invited all major EU-funded perovskite PV projects to the European Perovskite PV Days (EUPPVD) held at the University of Oxford. During two unusually sunny days at the British Oxfordshire, delegates from across Europe came together for intense discussions in the new Beecroft Building at the Department of Physics. On the … Read more
CHEOPS behind new initiative to increase transparency of perovskite research, through the introduction of a Unified Standard for Performance Measurement and Stability Testing of perovskite-based photovoltaic devices. Perovskite PV is the rising star among the third-generation solar cells. Since its discovery in 2012, research groups working with this remarkable semiconductor, have engineered advancements at a … Read more
In Neuchâtel (Switzerland), CHEOPS researchers from EPFL and CSEM have combined silicon- and perovskite-based solar cells. The resulting efficiency of 25.2% is a record for this type of tandem cell. Their innovative yet simple manufacturing technique could be directly integrated into existing production lines, and efficiency could eventually rise above 30%. In the field of … Read more
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 … Read more
