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. For most cells, RCH can be approximated by VOC divided by ISC: $$R_{CH} = {V_{MP} \over I_{MP}} \approx {V_{OC} \over I_{OC}} $$, RCH is in Ω (ohms) when using IMP or ISC as is typical in a module or full cell area. losses.
