1. Reasons for the increase of photovoltaic glass
Solar energy is mainly concentrated invisible light regionTherefore, it is of practical significance to improve the utilization of visible and near-infrared spectral regions.
Light in the air and glass interface each reflected light energy accounted for the total energy of the incident light4%, the transmitted light energy is96%, a piece of glass reflected twice,Ithrough=（0.96）2 IIn≈ 0.92 IIn .In addition, the glass will absorb the light through, different materials and different thickness of the glass to absorb the light is not the same.
2. The theoretical basis of photovoltaic glass
use of lightWaveThe principle of interference, in the glass surface coated with a layer of optical thickness of the film, different surfaces of the reflected light interference phase, according to the law of conservation of energy, photovoltaic glass transmittance increased. The principle is shown in the following figure:
