Glass surfaces are often unexploited for energy production although they are abundant especially in larger cities. New transparent solar cells can change this – an exciting option for the photovoltaic industry in the future!
A group of researchers at Michigan State University in East lancing deals with transparent solar cells for some time and has now presented its new concept of the public. Transparent Solar units were considered so far impossible, science brought it only until the development of semi-transparent systems. The reason for this is quite simple: the photovoltaic technology always converts some portion of the light spectrum into electricity, this part is no longer reflected back after striking the surface of the human eye. So the simple rule was considered so far: all the more transparent the solar cells, the lower the efficiency. That has now changed, the American scientists convince with a promising concept.
The new solar cells use the invisible for people portion of the light spectrum, namely the ultraviolet and the infrared part. The new controls can be easily on window panes is, without a color of glass to bring about or to hinder the view in a different way. The active layer is this tiny organic salt molecules that absorb light in the visible spectrum and therefore transparent effect. An industrial production of such plants is possible at an affordable price, from the Smartphone display glass office complex each kind can be thus equipped disk. That need to work on the efficiency of scientific but still, this is just at about one percent. An increase to 5 per cent will be in the range of what is possible: thus are the transparent solar cells still in the lower power range, to compensate but the enormously flexible use way back this disadvantage.
