Interesting question.
The ClearVue panel would harvest some (%?) of the UV and IR, so there would be less available, and this would reduce the amount available to the silicon panel. But as the ClearVue panel is transparent, most (but probably <70% ?) of the visible light would pass through it, so what was left would be available for capture by the silicon panel to generate electricity. However I would imagine that the combination would be overall less efficient overall because of the less than 100% transparency and other losses that are involved.
This is not to say that engineering an overcoating of the gel layer over a silicon panel and adding edge cells may not be a beneficial add-on if it could be done, but this would only be true if the ClearVue photovoltaic edge cells harvest a larger proportion of UV and IR than does the silicon, and if the losses within the gel's path length are less than those in the silicon panel. The concentration of light onto the edge cells would probably boost the conversion efficiency a bit. But I would predict that this arrangement may not be significantly better than the silicon panel alone, and may well be worse.
One factor here is the edge cells. I do not know how efficient ClearVue's edge cells are but current mono-crystalline silicon photovoltaics are around 20%. Poly-crystalline (amorphous) silicon cells are cheaper but less efficient. The much smaller areas of the edge cells probably allows ClearVue to use much more expensive but significantly more efficient photovoltaic material than silicon, such as gallium arsenide, so this would help significantly.
Wikipedia (https://en.wikipedia.org/wiki/Solar_cell_efficiency) provides a bit of helpful info:
Solar cell efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity.The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system. For example, a solar panel with 20% efficiency and an area of 1 m2 will produce 200 W at Standard Test Conditions, but it can produce more when the sun is high in the sky and will produce less in cloudy conditions or when the sun is low in the sky. In central Colorado, which receives annual insolation of 5.5 kWh/m2/day (or 230W/m2),[1] such a panel can be expected to produce 400 kWh of energy per year. However, in Michigan, which receives only 3.8 kWh/m2/day,[1] annual energy yield will drop to 280 kWh for the same panel. At more northerly European latitudes, yields are significantly lower: 175 kWh annual energy yield in southern England.[2]
Solar cell efficiencies vary from 6% for amorphous silicon-based solar cells to 44.0% with multiple-junction production cells and 44.4% with multiple dies assembled into a hybrid package.[14][15] Solar cell energy conversion efficiencies for commercially available multicrystalline Si solar cells are around 14-19%.[16] The highest efficiency cells have not always been the most economical — for example a 30% efficient multijunction cell based on exotic materials such as gallium arsenide or indium selenide produced at low volume might well cost one hundred times as much as an 8% efficient amorphous silicon cell in mass production, while delivering only about four times the output.
