Solar Thermal Management Materials

Since the beginning of civilization, humanity has built houses to sustain comfortable living conditions throughout the seasons. In our modern society, about 50% of the total energy consumption is used for heating and cooling. Growing demands for thermal management in many different sectors, from electronics to housing, inevitably mean increased energy consumption. The primary source of heat is coming from the combustion of fossil, bio or waste-based feedstocks, all contributing to carbon emissions.

In this lecture I will present how we are working on developing materials that capture, store, and release both solar and ambient heat without creating any emissions.

These solar thermal management materials are a unique combination of molecular photo-switches that capture and store solar energy, so-called MOST systems, that together with phase change materials (PCM) can contribute to thermal management. The two classes of materials operate at fundamentally different principles. The input of MOST system is photons, and the output is heat whereas PCM can absorb heat from the environment. By combining the two materials into one, we can harness and upgrade two of the most abundant renewable sources of energy on the planet: ambient heat and sunlight.

The talk will begin with introducing molecular synthesis and design principles, and then transition into materials function demonstrated in lab scale energy capture heat release as well heat to power devices.
