    摘要： A photovoltaic cell has a semiconductor substrate formed from semiconductor material doped by a first dopant type, and a doped region over at least a portion of the substrate. The doped region is doped by a second dopant type that is opposite to that of the first dopant type to form an emitter. Moreover, the doped region is doped to a region dopant level. In addition to the substrate and emitter, the cell also has a plurality of semiconductor fingers formed on the emitter, a plurality of busbars formed from a conductor and intersecting the plurality of semiconductor fingers, and a plurality of tabs soldered to the busbars. The fingers are doped by the second dopant type to have a second dopant level, which is greater than the region dopant level.

    摘要： A molecular recognition sensor system for detecting the presence and concentration of an analyte including a resistive sensor having a semiconductive polymer film which swells when exposed to an analyte and interferents and a molecular imprinted resistive sensor having a semiconductive polymer film imprinted with the analyte which thereby swells when exposed to interferents, a circuit connected to the resistive sensor and the molecular imprinted resistive sensor for detecting a change in the resistance of the resistive sensor when exposed to the analyte and the interferents, the change in the resistance of the molecular imprinted resistive sensor when exposed to the analyte and interferents, and for subtracting the change in resistance of the molecular imprinted resistive sensor from the change in resistance of the resistive sensor to reduce the effect of any interferents on the change in resistance of the resistive sensor thereby determining the presence and concentration of the analyte.
