A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light.. Individual solar cell devices are often the electrical

A Kelvin or four-wire measurement is essential to getting accurate IV data while testing a solar cell. A variable load is applied across the four wires in order to get a variety of current and voltage measurements for the device under test. Exactly what current and voltage is unknown until tested, which is why there is some iteration needed.
Connect the solar cell with the electric motor and a DMM to measure current. Change the angle of the solar cell from 0 to 60. Measure the angle with a protractor. Measure the solar cell current for given angles and observe the turn speed of the propeller of the electric motor. Record the results in table 4.
With just 1 PV cell in the circuit, shade 1/4 of the PV cell with a piece of cardboard or paper and take a reading. Shade 1/2, 3/4 and then all of the photovoltaic cell. Record the readings in Data Table 2. Table 2. Effect of Shading on Cell Current 3. Connect PV cells in series and take a reading.

It collects those positive and negative charges on two different terminals so they can be used to do work in an electric circuit. Solar cell efficiency is the ratio of the electrical output of a solar cell to the incident energy in the form of sunlight.
The relationship between the two might need to be adjusted for the resistances of the wires, as in the example we described above, but overall the four-wire measurement is a way to accurately get current and voltage information of a device. A Kelvin or four-wire measurement is essential to getting accurate IV data while testing a solar cell.
