WebJan 1, 2013 · The increase in ideality factor and saturation current is caused by the increase in the recombination current. The increase of the latter is linked with increasing density of defect states in the band gap. These defects are caused by the energy released from the recombination of electron-hole pairs. WebThis unique combination allows the recombination-active metal contacts to be displaced from the wafer surfaces, enabling record-high open-circuit voltages of up to 750. mV and efficiencies of up... car dealerships grand island nebraska

The result shows that the equivalent mean squared noise current is 2 3 of shot equivalent, i.e. i ng 2 = 2 3 [2qI g Δƒ]. The result is substantiated with experimental data. brokentalkers the blue boy
