Using nanowires to make ultra efficient low-cost solar cells

Trondheim, Norway (SPX) Nov 08, 2021 A research group at the Norwegian University of Science and Technology (NTNU) has developed a method for making an ultra-high material efficient solar cell using semiconductor nanowires. If this is placed on top of a traditional silicon-based solar cell, it could potentially double the efficiency of today's Si solar cells at low cost. "We have a new method of using gallium arsenide (GaAs)
