A review on energy conversion efficiency mechanisms in quantum dot intermediate band nanostructure solar cells

Quantum Dots used in so-called third-generation Solar Cells have the potential to significantly increase the photon conversion efficiency in two ways: (1) the production of multiple excitons from a single photon of sufficient energy and (2) the formation of intermediate bands in the bandgap that enhances its photogenerated current, via the two-step absorption of sub-band gap photons.   Key...

Compensating linear and non linear loads using distribution static compensator (DSTATCOM)

Distribution static compensator (DSTATCOM) is very popular in compensating the linear, nonlinear, balanced and unbalanced loads. Any change in the load affects the DC-link voltage (DCLV) directly. The proper operation of DSTATCOM requires variation of the DCLV within the prescribed limits. This paper presents modified synchronous reference frame (SRF) method for real time generation of compensating...
