Abstract :
Transparent silicon solar cells can lead to increased energy conversion efficiency by enabling the collection and conversion of photons near and below the silicon band gap. This can be accomplished through the use of a low band gap solar cell in multiple junction systems. This analysis shows that the potential energy conversion efficiency gain for a one sun system is 7%. The design and fabrication of a silicon cell transparent to low energy, infrared (IR), light is presented.
