SrTiO3 may be engineered for more efficient absorption of solar energy.

SrTiO3 absorbs ultraviolet light efficiently, but misses most of the solar spectrum. To tailor SrTiO3 and similar oxides for solar energy conversion – photovoltaic or photoelectrolysis – we examine the structural dependence of electronic properties, exploring epitaxial strain as a way to tune band energies.
