Limitations of photovoltaic cell: The limitation of photovoltaic cell is given bellow: 1. Efficiency is low about 20 percent. 2. Material cost is high because photovoltaic cell used all pure material. 3. Photovoltaic cell may not operate isothermally if so Carnot principle, efficiency limitation must be considered. 4. Cell material absorb incident ray. 5. Internal Ohomic resistance in external current and to the shunt.
