- the other walls of the module, perpendicular to the plane of the photovoltaic cells or facing it, are transparent in the visible and coated in this example with a luminous cascade material, for transforming the incident solar radiation into a radiation whose spectrum is shifted towards the range greater cell sensitivity photovoltaic, and a low-pass dichroic coating.
