A very thin layer of p-type semiconductor is grown on a relatively thicker n-type semiconductor. The current-voltage characteristic of a solar cell describes its behavior under load. The maximum utilisable power of a solar cell is dependent on the intensity of the incident light. Here for the calculation of the number of modules required in series and parallel, and power we have assumed that all the modules have identical parameters.

Write down the voltage, current and power values at the maximum power point.

A typical curve is shown in figure 1 (all variables and parmeters are defined below).

Solar cells, also called photovoltaic cells, are pieces of technology which harness the power of the sun to generate electricity.

When used with the Source Measure Unit, the I-V Curve PC software will allow you to: Perform I-V measurements between -10 V and 10 V, with voltage step sizes as low as 333 µV.

Note down the observation of voltage and current in Table 1. . Equipment 1 Solar battery, 4 cells, 2. .

and the solar cell is varied. . In the dark, its behaviour is identical to that of a diode.

LIST OF EXPERIMENTS S.

A solar cell is a device that uses sunlight to produce electricity. 1 The light has the effect of shifting the IV curve down into the fourth quadrant where power can be extracted from the diode.

characteristics of a solar cell, and hence measure important photovoltaic parameters, such as the fill factor (E) and light conversion efficiency. .

Soil–water characteristic curve (SWCC) and suction stress characteristic curve (SSCC), as the core of unsaturated soil mechanics, are important constitutive relationship curves for unsaturated soils, which can accurately describe the stress state in the soil.

. This curve shows how the voltage generated by the solar cel l varies with the current drawn from it.
