6 FAQs about [Solar cells increase absorption]

Why do solar cells have a higher absorber thickness?

In general, an increase in absorber thickness can result in higher values for two key parameters of the solar cell: short-circuit current and open-circuit voltage. This increase is attributed to the greater absorption of solar light by the solar cell, leading to a higher generation of charge carriers.

How IR absorption enhancement would benefit PCE increase of solar cell?
