What is a bifacial silicon solar panel?

The bifacial silicon-based cell architecture consists of PERC+, p -PERL, n -PERC, n -PERT, n-PERL, heterojunction, IBC and TOPCon cells. A typical bifacial silicon solar panel consists of a glass sheet on both front and back sides, a transparent polymer sheet and a thin silicon wafer layer with a shelf life of at least 25 years.

What is a monofacial solar panel?

This is precisely achieved from monofacial solar cells to bifacial solar cells. As discussed in the previous section, the monofacial solar panels are made up of either a p - or n-type silicon wafer layer covered on both sides with Ethylene Vinyl Acetylene (EVA), a polymer material kept as the cover to protect the silicon wafer.

Which antireflective coating is used in bifacial solar cells?

4.1.1. Silicon nitride Silicon Nitride is the most reliable and commonly used antireflective coating and passivating material in monofacial solar cells. The antireflective coating properties are good and can act as an effective passivation layer on the front side of the bifacial solar cells.

Are bifacial solar panels better than monofacial?

Under better albedo and proper mounting angles, a typical bifacial solar panel is expected to show 50% more power conversion efficiency than the monofacial counterpart. Bifacial silicon solar cells are monofacial cells with a back surface opened with a dielectric passivated layer, and a polymer back cover is replaced with a transparent sheet.
