Led by Prof. Jeffrey C. Grossman, ‘The Grossman Group’ at Massachusetts Institute of Technology works on a wide variety of energy related topics. Specific to solar energy, the main topics include Solar Thermal Fuels and Photovoltaics (PV).

Simply put, Solar Thermal Fuels topic refers to transferring & storing solar energy in the form of molecular bonds.  These are chemical bonds and once they are broken, the stored energy is released in the form of heat.

The main problems with Solar Thermal Fuels are that the materials are expensive and they degrade after a few cycles of energy conversion.

In Photovoltaics, semiconductor materials are used to produce electricity from sunlight. Prof. Grossman strongly believes in multidisciplinary perspective to solving problems with a wide spectrum of computational approaches. This vision is clear in the way the Grossman Group tackles Photovoltaics topic. They work includes several semiconductor materials used in forms of Quantum dot (QD), Monolayer-based, Amorphous-Si (a-Si), and 3-Dimensional solar cells. The 3-D solar cells is a new & unique concept and we will be following the Grossman Group’s work in this field with great interest. To simply put, the main idea behind the 3-D solar cells is the limitation that the movement of Earth causes with respect to 2-D solar cells deployed. These 2-D solar cells work the most efficient at certain part of the day due to the angle towards the sun. With 3-D solar cell approach, the Grossman Group is trying to overcome this limitation by having different parts of the solar cell structure face the sun with the perfect angle throughout the day.

Since the electricity is produced directly from sunlight, one of the main limitations of PV is that the solar cells do not work as efficient as they normally do in cloudy weather conditions. Similar to Solar Thermal Fuels, cost of the materials is again a big problem. Government incentives in US encourage the use of PV in households (in the form of solar panels) by helping tackle the latter problem.

These projects are currently funded by the National Science Foundation (NSF), Department of Energy, Defense Advanced Research Projects Agency, Defense Threat Reduction Agency, and MIT Energy Initiative.
