ALEX Lesson Plans
Subject: Science (8) Title: Alternative Energy Conversion: Photo Effect of Titanium Oxide in Aqueous Solution and Electrical Energy Production Using Solar Energy
Description: We present the photovoltaic effect of oxidized titanium (Ti) under laser excitation. This lesson is designed to demonstrate how sunlight can be used to produce voltage. This light to electrical energy conversion system is also referred as photovoltaic effect. The idea of the lesson is to produce electrical energy using a light absorbing semiconducting material, in this case TiO2, which can be made by either coating a conductive electrode with TiO2 nanoparticles or oxidizing a planer Ti plate in air. This setup can also be used to split water molecules into clean energy fuel (hydrogen). Two chemical reactions will be involved in this water splitting reaction. One oxidizes water into oxygen and the other reduces water into hydrogen. This lesson explores the effect of surface oxidation of Ti as well as the effect of a TiO2 coated glass on photovoltaic output. The lesson demonstrates how the top layer of oxide coating is critical for photovoltaic effect. Concepts of producing electric energy, chemical energy, and maximizing efficiency of photovoltaic effect will be introduced.
