The derivation of potential energy is discussed here. II. For AM1 (normal incidence) the power density is reduced to 925 W/cm 2 whereas for AM1.5 (45 o above the horizon) the power density is 844 W/m 2.The irregularities in the spectrum are due to absorption at specific photon energies. ���� Adobe d� �� C A single diode equivalent circuit for the ideal solar cell.

Solar cell, also called photovoltaic cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect.The overwhelming majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous (noncrystalline) to polycrystalline to crystalline (single crystal) silicon forms.
