The control device achieved a maximum power conversion ... The synergistic effect of 0.5 Sun albedo and a 20-degree tilt angle resulted in bifacial perovskite solar cells with an efficiency ...

“Future research could better investigate wind and albedo effects, different heights of solar panels above the roof and development of the vegetation and the effects of this changing vegetation ...

giving a high albedo effect. For six months the Poles receive no solar energy due to the Earth’s orbit and tilt.
