A collection of interesting things related to photovoltaics and my research.


PVTrace
pvtrace: optical monte-carlo simulation of luminescent photovoltaic devices.

PVTrace: Optical monte-carlo simulation of luminescent photovoltaic devices

PVTrace is open-source software for academic use, for more information (installation instructions) see the project pages at github.com. PVTrace can be licensed for commercial applications or I can be hired for consulting projects. Interested in knowing more? Please get in contact.


Quantum of Sol
Quantum of Sol: the next generation of solar cells in a WebApp.

Quantum of Sol: Now a Webapp! (Safari might be required -- Sorry!)

Quantum of Sol was our highly successful outreach adventure at the prestigious Royal Summer Science Exhibition 2009. Imperial College Physics students Matthias Kraft and Aidan Taylor joined me for their summer research project in 2010 and made a Web app to explain solar energy conversion. Their work illustrates the current/voltage trade off with conversional solar cells, and highlights how this can be circumvented by using the hot-carrier approach.


pydaq
Python software to control the analogue ports of National instruments DAQ 6008.

Python control of USB NI-DAQ.

National instruments make a very versatile USB Data Acquisition (DAQ) box. Let's face it, using the NI C API and programming on Windows are not the most inspiring tasks. I wrote a small python class that makes using this DAQ on Windows a bit more fun! You can find the pydaq project here on github.com. It makes it simple to access the current and voltage values on any of the port:
