European film solar research partner Solliance announced that the efficiency of series perovskite silicon solar cells is 26.3%.
Solliance stated that it has developed a perovskite solar cell with an average near-infrared transparency of 93%. It added that the Dutch Energy Research Center (ECN) has confirmed that when this perovskite cell is mechanically stacked in a 6-inch crystal for industrial processing His efficiency was 26.3% on silicon cells. This is 3.6 percentage points higher than the efficiency of laminated silicon panels that directly generate electricity.
ECN's Gianluca Coletti commented: 'This result shows that even on the basis of high-end crystalline silicon technology and industrial process technology, it is feasible to achieve significant efficiency gains.
The bottom battery contributed 9.9 percent to the series efficiency.
'The tested small translucent perovskite battery has an effective area of 0.09 square centimeters; the power conversion efficiency is 16.4%,' Sjoerd Veenstra, project manager of perovskite solar cells at Solliance, explained and added that the performance measurement of the four-terminal hybrid series is Based on accepted procedures.
Veenstra said: 'Now that the device is proven to have spin coating, we use a pilot plant provided by an industrial partner to extend it to a viable industrial production process.
