Solar cells are generally made from semiconducting materials, which are sensitive to structural and environmental factors, e.g, the light intensity, which depends on the power delivered by the solar cell.
I-V Characteristics of Solar Cell (II) Virtual Lab
General Aim of I-V Characteristics of Solar Cell (II) Experiment
To study the illumination dependence and the exposed area dependence of the I-V characteristics of the solar cell.
I-V Characteristics of Solar Cell (II) Experiment Method
A simple dc circuit with bias voltage, solar cell, variable resistance, ammeter, voltmeter, lamp and ac power supply to operate the lamp, variable area chopper plate.
Learning Objectives of I-V Solar Cell Characteristics Experiment (||)
Describe the construction and operation of the PV cell.
Enumerates the different factors that may affect the operation of the PV cell.
I-V Characteristics of Solar Cell Experiment Theory (ll)
I-V Solar Cell Characteristics Virtual Experiment (Il) Principle
In I-V Characteristics of Solar Cell (ll) experiment, by varying the ac voltage applied to the cell and measuring the short circuit current as a function of the lamp’ voltage, we can study the effect of the light intensity on the short circuit current obtained from the cell. In the second part, a chopper plate of controllable area limits the exposed area of the cell to the light intensity, allowing us to study the dependence of the I-V characteristics and the cell parameters maybe also studied.
