In this experiment, we were asked to use a solar cell, a light, a ruler, and some colored gels to determine different aspects of light intensity. Copyright © 2002-2021 Science Buddies. Here’s how to calculate the power the solar cell delivers to the motor: No filter produced the most electricity. Building a Simple Solar Oven, Are You in Hot Water? Interested in solar? How Does Solar Cell Output Vary with Incident Light Intensity? Since we were using a flashlight with a constant intensity, we needed to alter the intensity by instead changing the distance of the light to the solar cell for each trial. We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. This project is used to design a PV system with the help of nano solar cells.
