Inverse opals boost solar cell yields

INAC recently obtained excellent results on new dye-based solar cells, boosting yields by more than 10% and achieving current densities of nearly 20 mA/cm². The cells are based on a new-generation organic dye and electrodes made of titanium oxide “inverse opals” that more effectively trap and scatter light.

An inverse opal is a periodic honeycomb lattice structure in which a periodic assembly of microbeads occupies the lattice structure—the opposite of a naturally-occurring opal. The honeycomb structure multiplies the surface available to trap photons and increases conversion yields. INAC, which would like to pursue the development of these cost-effective and rare-metal-free dye-based solar cells, has reached a milestone with this latest advance.
