Teaching Materials (1-2 of 2)

1. Nanotechnology Invention and Design: Phase Changes, Energy, and Crystals

   Teaching Materials | 11 Jan 2017 | Contributor(s):: Daniella Duran, NNCI Nano

   This 3-part lesson introduces the nanoscale effect of various energy inputs on the crystal lattice of a smart material, Nitinol, and then invites students to become nanotechnology inventors. Students will first explore how energy exchanges lead to solid-state phase changes at the macroscale and...

2. Silicon Solar Cell Efficiency: Comparing Input Power to Output Power of a Silicon Photovoltaic Cell

   Teaching Materials | 28 Oct 2016 | Contributor(s):: Oskar Cymerman, NNCI Nano

   This lesson is designed to help students find a measure of a solar cell’s power conversion efficiency, by studying output power (Pout) of a silicon PV cell and comparing it to the input power (Pin) of incandescent light bulbs illuminating the PV from a set distance. In this activity,...
