a, A labelled scanning electron microscopy image of a silicon photovoltaic, 10 μm by 20 μm in size. b, A schematic cross-section of one of our photovoltaics. c, A current–voltage curve for a photovoltaic with (red curve) and without (blue curve) illumination. The devices were illuminated by a 785-nm wavelength laser with an intensity of 100 nW μm−2. The illuminated current–voltage curve shows an open circuit voltage (Voc) of approximately 700 mV.
