To achieve good photocurrent response in Al/SiOx/pSi MIS solar cells it is necessary to keep the Al barrier metal thickness to ≈50 Å. It is demonstrated that such solar cells are unstable, principally in Voc. The reduction in Voc is shown to be induced by photons of wavelength ⩽4500 Å. MIS cell stability can be improved, at the expense of efficiency, by thickening the barrier metal to 100 Å
