High Efficiency Solar Cell Using Adaptive Self-Cooling. [2105 - 2016] This is an award-winning project that uses an adaptively controlled thermoelectric heat pump, powered by a solar panel's own energy, to keep its temperature under control, thereby increasing its conversion efficiency and lowering the cost per watt of electricity produced [Slides] [Video]. The project was exhibited at the 2016 National Maker Faire, Washington, DC, and received numerous awards at other Science Fairs including:
- The project has also been featured in IEEE's "The Institute" magazine. [Link]
Development of a Novel Eco-Friendly Thermoelectric Air-Conditioning System. [2013 - 2014] A novel dc operated thermoelectric air conditioning system is developed that consumes significantly less energy than a vapor compression unit of similar size operating under identical heat loads. In addition, a method for optimizing the currents in each stage of a two-stage cascaded thermoelectric cooling system is developed theoretically and confirmed experimentally for the first time. The project was awarded 2nd place in the International Sustainable World (Energy, Engineering & Environment) Project Olympiad (I-SWEEEP), 2014.
Study of Infrared (IR) Absorption in Water and its Application in Filtering Heat Energy from Solar Radiation  In this project it is shown experimentally that water absorbs IR much more effectively than it absorbs visible light. This result is then applied to two practical cases: (a) filtering of IR radiation in sunlight before it enters the window of a house resulting in lower energy consumption, and (b) filtering IR from sunlight incident on a solar cell resulting in a higher solar cell voltage.The project was awarded 1st place in the Texas Science and Engineering Fair, 2012 and was a semifinalist in the 2012 Broadcom Masters competition.
