Monocrystalline P-type PERC stacked bifacial modules

What is a bifacial solar module?

LONGi launched its mono-PERC modules in 2016, featuring integrated PERC technology on monocrystalline silicon and low light degradation, and its cell efficiency has increased from 21% to 24.06%. Bifacial modules collect solar energy from both the front and back side of the module, increasing the total power output per module.

What is a common bifacial cell with crystalline silicon substrate?

Fig. 1 presents the cross section of a common bifacial cell with crystalline silicon substrate. Both p-type cells and n-type bifacial cells consist of a metallization grid, which is open, engrossed on both sides of the cell, to absorb irradiance from both sides.

Do C-Si PERC bifacial solar cells produce more power?

A simulation has been carried out to determine the capability of c-Si PERC bifacial solar cells to derive power compared to its monofacial counterpart. The results show that bifacial solar cell produces more J SC and power relative to monofacial cell.

What is a p-type bifacial cell?

Both p-type cells and n-type bifacial cells consist of a metallization grid, which is open, engrossed on both sides of the cell, to absorb irradiance from both sides. N-type bifacial cell consists of a p+ emitter as a diffused layer and the back surface field is an n+ layer. Fig. 1. Structure of n-type bifacial solar cell .
