Amorphous silicon is one of the key materials in the manufacturing of next-generation solar panels and flat-screen televisions. A recent study carried out by researchers from the University of Girona, with the support of laboratories operated by the University of Barcelona and the French National Centre for Scientific Research (CNRS) has revealed that the energy of amorphous silicon -- the state in which it exhibits the greatest stability -- is 50% lower than the value commonly accepted until now. According to the researchers, this information is important for understanding the structure of the material and improving its properties.
