Comment on Scientists make game-changing breakthrough that could slash costs of solar panels: 'Has the potential to contribute to the energy transition'

  With one layer the case is simple. There is a certain light energy at which the conversion of light to current occurs called gap energy. If the light energy is lower than that no conversion can happen and if the light energy is higher the extra energy is converted to heat and only gap energy remains.

  Filtering UV would be a loss but a small one.
