Well, its certainly got an odour of ophidian short-chain lipids about it.
Typical clear sky daylight is an order of magnitude less irradiance than direct sunlight. Overcast sky daylight is usually at least another order of magnitude down on that. Therefore at best, the energy density for worthwhile output without direct sunlight just isn't there unless the panels have a total installed cost per unit area of less than a tenth of that of conventional photovoltaic or solar thermal panels. To be a game-changer they'd need to be a hundred times cheaper.
