Entire solar spectrum multiplying converting platform unit for an optimal light to electricity conversion

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 () and with an upper electrode layer () characterized in that it comprises: an opto-phonic platform composed of a UV radiation light-to-light down converter () to a particular sub-band in the visible radiation domain, a harvesting diffractive grading component () including an electronic passivation layer () 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 the solar light are transmitted by this top nanolayer, guided to the dedicated panel area and focused on adjusted converters.
