Solar energy can be part of a mixture of renewable energy sources used to meet the need for electricity. Using photovoltaic cells (also called solar cells), solar energy can be converted into electricity. Solar cells produce direct current (DC) electricity and an inverter can be used to change this to alternating current (AC) electricity.
Objective. How efficient is a solar cell at converting the sun’s energy into power? How much power does a solar cell produce? The objective of this experiment is to explore solar cells as renewable energy sources and test their efficiency in converting solar radiation to electrical power. Theory. Solar Power.

Lesson on Photovoltaic Cells. In this lesson you will be introduced to the history and theory of Photovoltaic (PV) cells. You will also, hopefully, begin to realize the importance of PV cells and the career opportunities available in this area of intense materials science research.
In one solar panel there are many individual solar cells. Solar cells are sometimes called ‘photovoltaic’ or ‘PV’ cells (from the Greek word ‘photo’ meaning ‘light’, and ‘voltaic’ meaning voltage or electrical current). The PV cells in a panel can be wired to any desired voltage and current by connecting them in series to ...
Photovoltaic Cells. Part 1: In this lab you will gather data to answer each of the four questions below (~30 minutes per question), to learn about what variables affect the power a solar cell produces. Question 1: How does shading affect the power that a solar cell can produce?
Experiment with solar power by building your own solar-powered robot or oven or by testing ways to speed up an existing solar car. Or analyze how solar cells or panels work.
