This is how bifacial solar modules increase the efficiency of PV systems
Conventional or monofacial photovoltaic modules are designed in such a way that they make optimal use of sunlight coming from the front. Bifacial (literally “two-faced”) modules, on the other hand, have photoactive cells on both sides. This property allows them to also convert reflected sunlight that hits the back of the modules into solar power. The production of the module types differs only slightly from each other, more precisely through a modification of the rear contacts. While monofacial modules have an opaque rear film, bifacial modules are usually transparent and therefore translucent. This allows the photons to penetrate the solar cells from both sides, thereby increasing the efficiency of the entire module.
