Abstract:
This invention relates to a solar energy collector that converts solar radiation into both electrical and thermal energy. More specifically this invention relates to a concentrating solar energy collector with an integrated construction that minimizes cost, bulk, and weight, and maximizes overall efficiency. Typical non-concentrating solar collectors use photovoltaic cells over the entirety of their surface. These solar cells are the most expensive part of the collector. This invention discloses using a reflector to concentrate the incident radiation on photovoltaic cells with one-twentieth the area of the reflector, and transferring the co-generated thermal energy into a working fluid pumped through the cell support structure.
Abstract:
A sample element for use with an analyte detection system comprises a supply opening (808a) configured to receive a material sample. A separator (808b) communicates with the supply opening (808a) , and separates an element of interest from the material sample. A sample chamber (802,804) communicates with the separator (808b) and receives the element of interest.
