It is true.
Because it is possible to have direct absorption of the photon directly into bandgap contents, but if an indirect bandgap material is to absorb a photon, then a phonon must be absorbed or emitted.
This means that the absorption length of light is in an indirect bandgap material like silicon.
Therefore silicon solar cells have to be thicker than those made from direct interval material such as gallium arsenide and which can be made as a thin film cell.
Silicone is a simple material to work, and is more economical than many other direct interval materials.
The life of the stimulated carrier is longer in an indirect contrast, this can lead to slightly better efficiency.
