PV Characterization Lab

Overview

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 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.
