Multifunctional photovoltaic skylight with dynamic solar heat gain coefficient and/or methods of making the same

A building integrated photovoltaic (BIPV) product, comprising:

• first and second glass substrates arranged substantially in parallel and spaced apart from each other;
• a first gap between the first and second substrates;
• an inert gas in the first gap;
• a lenticular array comprising first and second sub-lens arrays, each sub-lens array comprising plano-convex lenses, the first and second sub-lens arrays being laminated to one another via laminating material comprising polyvinyl butyral (PVB) such that the planar sides of the first and second sub-lens arrays are adjacent to one another and each of the planar sides contacting the laminating material;
• and
• the second substrate supporting a plurality of generally elongate solar cell strips,
• wherein the lenticular array and the substrates are oriented relative to one another and configured such that the product has different solar heat gain coefficients (SHGCs) at the same time of day during at least first and second times of the year, respectively, and such that different amounts of direct sunlight impinge upon the solar cell strips at the first and second times of the year, and wherein the lenticular array and the second substrate are movable with respect to one another, as between at least first and second predefined positions, each said predefined position having an associated SHGC.
