Bifacial Cell Technology | SCHMID Group

Bifacial cells absorb light and generate electricity on both surfaces

In recent years SCHMID has developed several equipment for the production of bifacial solar cells. This cell type absorbs light and generates electricity on both surfaces and achieves up to 30 % higher yield than conventional cells, if suitably installed in open areas or flat roofs.SCHMID’s Bifacial Cell Technology

Bifacial cell looks similar from both sides
Front: collecting emitter / Back: back-surface-field (BSF)
Grid-shaped electrodes on front and back
Can be interconnected using standard stringer technology (5BB or multiwire)
Module rear side: transparent back-sheet or glass
Rear light collection increases energy yield up to 30 %

Bifacial cells can be either adapted for monocrystalline material (PERC) or for multicrystalline material (PERT).

Up to 30 % higher energy harvest than a conventional module
Best CoO in benchmark
Complete process out of one hand
Smart process sequence with proven production equipment
