Team demonstrates great promise of all-inorganic perovskite solar cells for improving solar cell efficiency

Team demonstrates great promise of all-inorganic perovskite solar cells for improving solar cell efficiency Hybrid organic-inorganic perovskites have already demonstrated high photovoltaic efficiencies of greater than 25%. The prevailing wisdom in the field is that the organic (carbon- and hydrogen-containing) molecules in the material are crucial to achieving this impressive performance because they are believed to suppress defect-assisted carrier recombination. New research in the UC Santa Barbara materials department has shown not only that this assumption is incorrect, but also that all-inorganic materials have the potential for outperforming hybrid perovskites. The findings are published in the article "All-inorganic halide perovskites as candidates for efficient solar cells," which appears on the cover of the October 20 issue of the journal Cell Reports Physical Science. "To compare the materials, we performed comprehensive …
