Abstract:
The invention relates to a device for evaporating a liquid, in particular water, comprising a housing (21) having a liquid inlet (12) for the liquid to flow into the housing (21) and a steam outlet (13) for withdrawing evaporated liquid, and a rotor (22) that is rotatably mounted in the housing (21), wherein a gap (27) is formed between the inner surface of the housing (21) and the outer surface of the rotor (22), with liquid spontaneously evaporating in said gap upon rotation of the rotor when subjected to shear action. The invention further relates to a device for treating water with such a device and to a filter for separating non-volatile matter, in particular salt, from the evaporated water.
Abstract:
The present invention relates to a photovoltaic device, in particular thin layer photovoltaic device, comprising a first transparent electrode, a first semiconductor layer comprising particles of a first semiconductor material, a second semiconductor layer comprising particles of a second semiconductor material, and a second electrode, wherein the first and the second semiconductor material are different materials, and wherein the particles of the first and the second semiconductor material have an average grain size in the range of 0.1-20 μm, preferably 1-10 μm, as well as to photovoltaic panels comprising two or more of such photovoltaic devices. According to another aspect, the present invention is concerned with a method of manufacturing such photovoltaic devices by way of printing in particular screen printing. Finally the present invention relates to the use of a mixture comprising a binder and semiconductor particles having a grain size in the range of 1 to 10 μm in the manufacture of photovoltaic devices. The photovoltaic devices of the invention excel in their efficiency and show remarkable performance even at low or diffuse light. Moreover, they exhibit high degradation stability and can be used in a broad temperature range such as -40 to +100 °C.
