Unfortunately, the material used in the solar cell absorbs only visible energy from the sun. The light that gets to the solar cell is made of different wavelengths. In order for it to be absorbed by the cell a photon from the light wavelength needs to pair with an electron in the cell itself. These pairs cannot occur if the photon does not have enough energy to pair, or has too much energy to pair with an electron in the solar cell. It is this phenomenon that occurs that causes an up to seventy percent energy loss within the solar cell.
