Today I finished up the main content in the Electrochemistry unit. I talked about electrolysis and the stoichiometry of a redox reaction and did several calculations that will be helpful for experiment #29.
We then discussed photovoltaic cells. I gave a very brief description during class, but if you wanted to see a more in depth explanation click on this link, which explains How Solar Cells Work. Another article found here discusses how the cost of photovoltaics has been decreasing over the years as well.
