Nanowires are Hot

by Griffin Merians

A study conducted in Taiwan and published in Nanoscale Research Letters, found that the use of silicon nanowires can be used to improve solar thermal energy efficiency. Solar energy is the most abundant source of renewable energy on our planet, and using thermal energy to capture this energy could play a key role in increasing our use of this form of alternative energy. Solar thermal energy is comparatively inexpensive, easy to implement, and efficient compared to many other forms of energy, and using silicon nanowires could be the latest breakthrough in improving this efficiency. Silicon and silicon nanowires are used extensively in photovoltaic electrical energy generation, but have not traditionally been used extensively in thermal energy collection. However, new research into the thermal properties of silicon nanowires has found they are significantly more efficient in thermal conversion than traditional silicon plates. Continue reading
