A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon

Solar radiation spectrum has maximum intensity for energy value of approximately 1.5 eV. So , semiconductor with band gap ~1.5 eV or less (e.g. Si) are preferred . GaAs has band gap of ~1.53 eV but has very large absorbing capacity hence they are preferred.
