Solar Energy Science Fair Project

Solar Cells and Temperature

Solar Cells and Temperature | Science Fair Projects | STEM Projects
In this experiment, you'll explore how the temperature of solar cells affects their power output. You'll measure the voltage and current of three different solar cells, each with a different temperature, and compare the results.


The hypothesis is that solar cells will have a lower power output at higher temperatures.

Method & Materials

You will assemble three solar cells with different temperatures, measure the voltage and current of each, and compare the results.
You will need 3 polycrystalline solar cells, a digital voltmeter, an ammeter, a resistor, a panel-mounted fan, a metal plate, 4 pieces of pan head screws, 16 M5 nuts, 2 pieces of plywood, and a handheld infrared thermometer.


The results show that the solar cell with the lowest temperature had the highest output power, proving that solar cells lose their efficiency at higher temperatures.

Why do this project?

This science project is interesting because it explores the effects of temperature on solar cells, which are a clean and environment-friendly way of generating power.

Also Consider

Experiment variations include repeating the experiment using water to cool the solar cell, and repeating the experiment using amorphous solar cells.
