Photovoltaic properties of Si samples with Ge quantum dots were studied. Photosensitivity spectra and current-voltage characteristics at 90 and 290 K were investigated. Negative photoconductivity of samples was revealed in the spectral range of 0.6 to 1.1 eV. Irregular temperature dependence of phot...
