Bifaciality can be implemented by varieties of architectures for solar cells, modules and in addition there are even many more applications on system level. This makes bifaciality a complex technology. Currently there is some confusion in the PV community what bifacial gains can be expected and how these transfer to the cost reduction and lowering the LCOE of the system. In this article we will describe how bifacial gains are defined, what bifacial gains can be expected and what this means for real applications.
