2. Experimental
2.1. Samples
Five photovoltaic modules based on dye-sensitized solar cells were analyzed. These modules were produced by
Glass2Energy, a Swiss company which is developing semi-transparent photovoltaic modules to facilitate
architectural integration of renewable energy in the buildings. These products are particularly promising because
they can be laminated to the glass pane of a classical double (or triple) glazing and be installed as a regular window.
Table 1 lists the products which were measured.
