Introduction. Bifacial solar cells refer to a particular device architecture designed to absorb light simultaneously from both the front side (sunward) and rear side of the device. 1 Solar irradiation at the rear side originates from the albedo, i.e., the reflected and scattered light from the ground. 2 Thanks to the extra photons arising from the …

A well-designed silicon heterojunction module has an expected nominal lifespan of more than 30 years, with an expected average performance ratio of 75%. Failure, power losses and degradation of SHJ cells and modules can be categorised by the affected parameter (eg. open-circuit voltage, short-circuit current and fill factor). losses are generally attributed to reduction in passivatio…
Bifacial perovskite solar cells (PSCs) have accentuated a great deal of attention to achieve a higher power output per unit area by utilizing albedo compared to conventional monofacial solar cells with a very low additional manufacturing cost.
