Some of these covered characteristics pertain to the workings within the cell structure (e.g., charge carrier lifetimes) while the majority of the highlighted characteristics help establish the macro per-formance of the finished solar cell (e.g., spectral response, maximum power out-put).
The spectral responsivity of a solar cell, R, – which quantifies the wavelength dependence of the cell’s photocurrent generation when normalized for the input ir-radiance or the radiant power of the incident monochromatic radiation – is a very informative and thus useful photovoltaic characteristic[11–18].
Home » Renewable Energy » Photovoltaic (PV) Cell: Characteristics and Parameters PV cell characterization involves measuring the cell’s electrical performance characteristics to determine conversion efficiency and critical parameters. The conversion efficiency is a measure of how much incident light energy is converted into electrical energy.
The solar cell characterizations covered in this chapter address the electrical power generating capabilities of the cell.
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.
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.
