  • Patent number: 10835900
    Abstract: An EWOD device for processing multiple droplets through multiple temperature zones. The device is configured to achieve a high spatial density of temperature zones with a wide temperature difference between hot and cold zones. A first set of temperature control elements is arranged above (or below) a fluid gap in an EWOD device and a second set of temperature control elements is arranged below (or above) the fluid gap. A temperature control element of one set is offset from temperature control elements of the other set in the plane of the fluid gap. The temperature control element of one set may be located at a different separation from the fluid gap to the temperature control element of the other set. The device has an optional temperature control element and/or arrangement which offsets the low temperature point from the inlet temperature. The two sets of temperature control elements are substantially interacting, in the sense that they cannot be considered to be thermally isolated from one another.

The InxGa1-xN layer is of i-type or n-type. The metal layer is interposed between the photoelectric conversion layer and the InxGa1-xN layer. When irradiating the anode electrode with light, a first light part included in the light is absorbed by the InxGa1-xN layer and a second light part included in the light travels through the InxGa1-xN layer. The second light part is absorbed by the photoelectric conversion layer to generate electric power in the photoelectric conversion layer. The second light part has a longer wavelength than the first light part. The carbon dioxide contained in the first electrolyte solution is reduced on the cathode electrode.
