The major difference for a bifacial module is that white reflectors are being included in-between the cells so that the front side power is not reduced due to the light escaping through the openings between the solar cells instead of being reflected back into the module as it would in monofacial modules with white backsheet.
In bifacial modules, the rear side cover consists of either glass or a transparent polymer back sheet. When backsheets are used, the module must be supported by an aluminium frame but the rigidity of the glass-glass modules is enough that in some cases a frame is not needed and the edges are only sealed.
Bifacial modules—those that are sensitive to light incident from both sides—are finally available at the same price per watt peak as their standard monofacial equivalents.
The reason for this is that bifacial solar cells are the result of an evolution of crystalline Si PV cell technology and, at the same time, module producers are increasingly switching to double glass modules anyway due to the improved module lifetimes, which allows them to offer longer product warrantees.
Degradation due to potential differences has been seen in bifacial PV modules based on both n-type [28, 29] and p-type [24, 30] cells. Components of the module packaging such as frame, glass, and encapsulant have been shown to play an important role in the extent of PID degradation of PV modules.
Bifacial PID of bifacial p-PERC solar cells when using glass/glass module: PID-s occurring at the front/emitter side and PID-p occurring at the rear side of the solar cell .

A constant uptrend in the power conversion efficiency of these various crystalline silicon based solar cells has been thus observed.
