Source sentences:
text: They showed that efficiencies of almost 10% were achievable using the 'sensitized' TiO 2 architecture with the solid-state hole transporter, but higher efficiencies, above 10%, were attained by replacing it with an inert scaffold.
text: When paired with microcrystalline silicon in tandem and triple-junction solar cells, however, higher efficiency can be attained than with single-junction solar cells.
