Fill Factor Losses in mc-Si Solar Cells [PDF]
Non-fundamental losses in mc-Si solar cells have been studied. These efficiency losses significantly depend on diode quality and parasitic ohmic resistances that result in the fill factor losses.

Optimization of Fill Factor Equation in Halbach Design [PDF]
Selection (spatial in homogenous) and excitation (spatially homogenous) fields are designed with Halbach magnets for magnetic particle imaging (MPI) and magnetic resonance imaging (MRI). Permanent magnet parameters (length and remanent flux density) and geometrical parameters (fill factor (FF), number of magnets, and system radius) are key factors for ...

Fill factor analysis of solar cells' current-voltage curves [PDF]
S.511-515After completion of the solar cell manufacturing process the current-density versus voltage curves (J(U) curves) are measured to determine the solar cell's efficiency and the mechanisms limiting the efficiency. An accurate and robust analysis of

Competition between recombination and extraction of free charges determines the fill factor of organic solar cells. [PDF]
Among the parameters that characterize a solar cell and define its power-conversion efficiency, the fill factor is the least well understood, making targeted improvements difficult.

Filling-Factor-Dependent Magnetophonon Resonance in Graphene [PDF]
We describe a peculiar fine structure acquired by the in-plane optical phonon at the Gamma-point in graphene when it is brought into resonance with one of the inter-Landau-level transitions in this material. The effect is most pronounced when this lattice mode (associated with the G-band in graphene Raman spectrum) is in resonance with inter-Landau ...

Silicon heterojunction solar cells toward higher fill factor [PDF]
One of the most limiting factors in the record conversion efficiency of amorphous/crystalline silicon heterojunction solar cells is the not impressive fill factor value.
