Jolywood Inks Pact with Imec to Develop Bifacial Solar Cells

As per the deal, Imec has also demonstrated screen-printed monofacial n-PERT cells with the conversion efficiency up to 22.8 percent.

Jolywood (Taizhou) Solar Technology has entered into partnership with Imec to develop industrialized bifacial solar cells with average front-side conversion efficiency up to 21.9 percent.

As per the deal, Imec has also demonstrated screen-printed monofacial n-PERT cells with the conversion efficiency up to 22.8 percent.

Commenting on the development, Jolywood, R&D Director, Dr. Zhifeng Liu said, “Jolywood is at the forefront of the n-type industrial technological developments in the PV industry, so we’re very satisfied with the close collaboration with Imec, the world-leading PV research institution.”

“And we’re very delighted with the excellent progress in the development of the high-efficiency bifacial n-PERT solar cells that have come as part of our collaboration. With our strong commercialization capabilities and experience, we look forward to transferring the achievements into commercial production,” Liu added.

Further, the new bifacial cells developed by both the companies use narrow (~40 μm) printed silver (Ag) fingers on the front side and printed aluminum (Al) fingers on the rear, the latter making contact with the emitter.

By using Al instead of AgAl for the rear contacts, the cost per cell is lowered to US$0.01/Wp. On a batch of M2-sized cells (area: 244.3 cm²), an average conversion efficiency of 21.9 percent was demonstrated, with the best cell topping 22.1 percent.

Used in bifacial operations under standard front illumination conditions in conjunction with an additional 0.15 sun rear illumination, these cells can achieve an efficiency of 25 percent.

Additionally, Imec also fabricates screen-printed monofacial n-PERT cells with efficiencies up to 22.8 percent, which is a state-of-the-art result for an industry-compatible fabrication process.

Also, the PV module has been proven compliant with the essential requirements, and a certificate from TÜV SÜD, the prestigious German product testing organization.

Jolywood is the world leader in the development, production and marketing of high-efficiency mono-crystalline N-type bifacial solar cells.
