European film solar research partner Solliance announced that the efficiency of series perovskite silicon solar cells is 26.3%.

Solliance said it has developed perovskite solar cells 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 on an industrially processed 6-inch crystalline silicon cell, its efficiency is 26.3%. This is 3.6 percentage points higher than the efficiency of laminated silicon panels that generate electricity directly.

ECN's Gianluca Coletti commented: "This result shows that even in the 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%," Sollier Veenstra, Solliance's perovskite solar cell project manager, explained and added that the performance measurement of the four-terminal hybrid series is According to accepted procedures.

Veenstra said: "Now that the equipment has been proven to have a spin coating, we have extended it to viable industrial production processes using pilot facilities provided by industrial partners.
