New photonic material for self-aligning solar cells
US scientists have made light-tracking, three-junction tandem PV cells with an active area of 650 × 650 square micrometers. They are based on indium gallium phosphide, gallium arsenide, and indium gallium arsenide antimony nitride and use photonic crystal film for maximum efficiency.
More haste, less speed – or momentum – for PV efficiency related research
Physicists at MIT and in Haifa have come up with a theory for slowing down light that could dramatically improve solar PV cell efficiency – the question now is whether it will work in practice, and on silicon.
