With increasing environmental concerns and greenhouse effects, almost every country is looking for ways to mitigate these concerns. Solar energy reaching the Earth’s surface provides an energy supply potential surpassing the power consumption of our civilization by three orders of magnitude. Even though solar energy seems to be our future, one of the current limitations in use of the solar thermal energy is that it is only available when there is sunlight, preventing solar-generated electricity from being produced during cloudy periods or overnight. Technologies that can store solar thermal energy and discharge it on demand to meet user needs will…
