A photovoltaic cell with enhanced transmissivity of infrared radiation. The photovoltaic cell includes a layer of photovoltaic material (403) having a front, light-receiving surface and a back surface. The photovoltaic cell further includes a first anti-reflective coating (ARC) layer (405) provided on (or making up) the front surface of the layer of the photovoltaic material (403) and a second ARC layer (405) provided on (or making up) the back surface of the layer of the photovoltaic material (403). The layer of photovoltaic material (403) may be a silicon substrate, and at least one of the ARC layers (405) may be formed as a black silicon region or layer in the silicon substrate (403). The photovoltaic cell may also include a front grid pattern (401) of electrical conductors (406) applied to the first ARC layer and a back grid pattern (401) of electrical conductors (406) applied to the second ARC layer.
