Overview
Solar cells produce different voltages and currents depending on the light levels and resistance in the circuit. How can you tell what the peak power of solar cell is? This is the method that researcher use to measure and compare the power from various solar cells. This is a good high school or introductory undergrad lab for physics or chemistry. It uses a simple technique with computer probeware to measure the current/voltage curve of a solar cell in order to determine its peak power. It allows you compare various types of cells and shows how difficult it is to get an accurate absolute measurement of performance.
