Hydrogen annealing for CZTS solar cells

Education and Research

Education and Research

Solar cells that combine two or more different semiconductor materials to absorb a wider range of the solar spectrum, thereby increasing overall efficiency. Perovskite is being explored for use in tandem approaches with silicon.

Solar cells made from Cu₂ZnSnS₄, an earth-abundant, non-toxic semiconductor material that is a promising alternative to silicon.

A process where solar cells are heated in a hydrogen atmosphere to subtly alter the material's structure, improving performance.
