The working of solar cell is based on photovoltaic effect. It is a effect in which current or voltage is generated when exposed to light. Through this effect solar cells convert sunlight into electrical energy. A depletion layer is formed at the junction of the N type and P type semiconductor material.
For a specific radiation intensity, the power curve above can be derived by multiplying all voltages, from short-circuit to open-circuit, point for point. The current will be at its minimum (zero) and the voltage across the cell will be at its maximum when the solar cell is open-circuited, which is not linked to any load.
Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.
The diagram illustrates the conversion of sunlight into electricity via semiconductors, highlighting the key elements: layers of silicon, metal contacts, anti-reflective coating, and the electric field created by the junction between n-type and p-type silicon. The solar cell diagram showcases the working mechanism of a photovoltaic (PV) cell.
The V - I characteristics of the solar cell or the current-voltage (I-V) characteristics of a typical silicon PV cell operating under typical circumstances are displayed in the graph above. The output current and voltage of a single solar cell or solar panel determine how much power it can produce ( I x V ).
