New research demonstrates great promise of all-inorganic perovskite solar cells for improving the efficiencies of solar cells.
Hybrid organic-inorganic perovskites have already demonstrated very 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 …
