The invention concerns the use of a perovskite oxide as a charge mediator in a sensitised solar cell (SSC), the perovskite oxide having the formula AB(X)3-δ, wherein A is an alkali metal ion, an alkaline earth metal ion, a transition metal ion, a p-block element cation or a rare earth metal ion; B is an alkaline earth metal ion, a transition metal ion, a p-block element cation or a rare earth metal ion; X is an oxygen anion; and δ is zero to 0.3.The perovskite oxide may be used as the main charge transfer relay mediator in the absence of added iodine and is optionally deposited on an electrode or dispersed in an ionic liquid, ionic solid, eutectic ionic melt or solid state hole conductor.
