Abstract
The invention relates to a high yield multistage light-to-electricity multiplying platform unit which is provided on its front face with a protection antireflection coating or layer (1) and with an upper electrode layer (5) characterized in that it comprises: an opto-phonic platform composed of a UV radiation light-to-light down converter (2) to a particular sub-band in the visible radiation domain, a harvesting diffractive grading component (3) including an electronic passivation layer (4) and with light splitting means and one or more sub-band light into narrowed sub-band light concentration converter(s), a IR radiation up conversion dedicated light converter, a converting multiplying platform made of several optimal for each narrowed and concentrated sub-band light-to-electricity multiplying converters. A digital optical light management layer on the top, collects, filters, splits and concentrates sunlight into sub-bands and to project them onto dedicated light-to-electricity preferentially all-silicon converters with low-energy multiplication capacity. The UV wavelengths are absorbed and down-converted within the top nanolayer of the platform. The other spectral components of t…
