Inter-metallic bonding could remove unwanted carrier barriers from multi-junction solar cells assembled by stacking finished single-junction cells, according to North Carolina State University. “We want to create high efficiency solar cells at a reasonable cost,” said engineering professor Salah Bedair. “Silicon-based thin solar cells are very popular because the material has around 20% efficiency and the ...
