One of the causes in low efficiency capturing solar radiation via solar cells is the reflection loss. A lot of research on this has resulted in many approaches such as nano-structures to reduce this reflection. An alternative is to embrace reflection. How?
The sun shines on a collector opening and this light is reflected down into a ‘pipe’ or channel. The angle of the reflectors cause the light to bounce from one side to another. Now instead of mirrors being used as reflectors, we use solar cells. Thus, instead of larger solar farms we would have wider and deeper light capture networks. Since the reflection occurs within the channel, this structure can be buried in the ground.
Unknown at this point are the parameters of this pipe or channel? Is this really feasible as large structures or only efficient at nano-scales?
