Photovoltaic modules are being perfected continuously in order to increase their energy yield and reduce their prices. Has developed high-transmittance glass with a special surface pattern to help achieve this aim.
The Surface Pattern Glass:
The front glass has a deep pyramidal pattern with the edges and corners blended. The very low iron coated of the glass material increases its energy and light transmittance.
The pyramidal pattern described above reduces the major source of solar energy loss at the air-glass interface. The solar radiation incident on the glass surface is not reflected back into the air but rather inside the glass. The light is refracted on another face of the pattern and thus part of the radiation which (with plain glass) is normally lost to the environment is reflected back onto the solar cell (internal trapping). This increases the radiation quantity incident on the cell and subsequently the energy yield.
