The characteristics of Photovoltaic (PV) cells can be understood in the terms of following terminologies: Efficiency: Determines the ability to convert sunlight into electricity, typically measured as a percentage. Open-Circuit Voltage (Voc): Maximum voltage produced when not connected to any external load.
Other important characteristics include how the current varies as a function of the output voltage and as a function of light intensity or irradiance. The current-voltage (I-V) curve for a PV cell shows that the current is essentially constant over a range of output voltages for a specified amount of incident light energy.
Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
The construction of a photovoltaic cell involves several key components and materials. A detail of such components and method is discussed below: Semiconductor Material: Photovoltaic cells are typically made from silicon, a semiconductor material that has the ability to absorb photons of sunlight and release electrons.
A solar cell is a semiconductor device that can convert solar radiation into electricity. Its ability to convert sunlight into electricity without an intermediate conversion makes it unique to harness the available solar energy into useful electricity. That is why they are called Solar Photovoltaic cells. Fig. 1 shows a typical solar cell.
Several factors determine the efficiency of a PV cell: the type of cell, the reflectance efficiency of the cell’s surface, the thermodynamic efficiency limit, the quantum efficiency, the maximum power point, and internal resistances. When light photons strike the PV cell, some are reflected and some are absorbed.
