To go a step further, the use of silicon carbide for energy conversion, which is often used in electronic systems, can increase the efficiency of solar systems. For example, a solar inverter can save 10 megawatts per gigawatt hour - and this is achieved by using this component instead of silicon, which represents considerable energy savings.
19/3/2020· Palmour: Silicon has a bandgap of 1.1 electronvolts, and that is basically the definition of how much energy it takes to rip an electron out of the bond between two silicon atoms. So it takes 1.1 electronvolts to yank an electron out of that bond. Silicon carbide as a band gap of 3.2 electronvolts, and so it takes 3 times more energy.
