The PV Lighthouse website is a free online resource for photovoltaic scientists and engineers. It provides calculators that simulate various aspects of solar cell operation, a library of refractive index data, links to photovoltaic software, and more.

Please contact us if you would like us to convert your simulation program into an online calculator, to host your program, or to post a link to your software.
