Today, about 95 percent of solar cells are made using crystalline silicon (c-Si). Most commercial designs employ a c-Si photoactive layer with a thickness of around 160–170 μm. However, since silicon alone makes up nearly half the cost of each solar panel, experts believe that next-generation c-Si solar cells will be much thinner.

Additionally, a thicker absorber can potentially increase recombination losses of charge carriers within the solar cell, resulting in a reduced fill factor.
