PV project owners could ramp up their financial gains by harvesting crops and generating solar power from the same land, with gross financial gains of 2.5% for basil and 35% for spinach grown in greenhouses with tinted semi-transparent PV modules.
New research suggests that using tinted semi-transparent modules could lead to better results. Polysolar, a Taiwan-based manufacturer of 20% transparent solar glass, has supplied the research modules. The thin‐film amorphous silicon modules have a transparent zinc oxide back conductive layer and clear front glass coated with fluorine tin oxide. The photovoltaic area of the modules is laminated in between two sheets of glass. According to the research paper the modules prompt 8% conversion efficiency and thus have an output of 66 W m−2.Thin-film amorphous silicon greenhouses begin to sprout – pv magazine International
