Calibration of an Au-coated Quartz Crystal

Posted on 1 September 2016

The purpose of this Application Note is to show the reader a simple experiment where we reduce Cu2+ onto an Au electrode and then oxidize Cu back off. We will then use the result to calculate a calibration factor for the crystal. Conversely, we will show you how to calculate the molar mass of the species deposited using a calibration factor.

Measuring the Optical Power of your LED

Posted on 27 February 2016

When performing experiments with dye solar cells, light is focused on the cell and its current response is measured. The generated current depends strongly on the intensity of the light. In order to calculate the efficiency of a solar cell, the optical power of the incident light has to be known. This technical note explains how to measure and calculate the optical power of your light source.
