Recombination Velocity

The aim of this work is to present a study of the recombination velocities at the junction initiating the shortcircuit (Sfsc) and limiting the open circuit (Sfoc) of a silicon solar cell under magnetic field in the static regime. From the continuity equation, the density of minority charge carriers in the base, the photocurrent density, and the phototension are determined. The study of the photocurrent density and the phototension, as a function of the junction recombination velocity, makes it possible to determine the recombination velocities at the junction initiating the short-circuit and limiting the open circuit respectively. From the profile of the variation of the photocurrent density and of the phototension as a function of the junction recombination velocity, a technique for determining the junction recombination velocities initiating the short circuit situation and limiting the open circuit is presented.

High-performance ultrafine silver powder used as crystalline silicon solar cell front conductive paste was prepared by chemical liquid-phase reduction method using silver nitrate as metal source, ascorbic acid as reductant, and gelatin as dispersant. The effects of reducing agent concentration, doses of dispersant, PH value of reaction solution and reaction temperature on the performance of silver powder were studied. The morphology, particle size and dispersibility of silver powder were observed by scanning electron microscope (SEM). The size distribution of silver particles was characterized by laser particle size analyzer. The crystalline silicon solar cells were produced by screen-printing front conductive silver paste, made with the obtained silver powder. The photoelectric properties of the solar cells were measured by solar simulator. The processing parameters of preparation silver powder, which meets the requirement of making high conversion efficiency solar cells, were optimized.

The pyramid-like textured ZnO film was prepared directly by magnetron sputtering on the self-supporting substrate of ZnO:Al film fabricated by sol-gel. The performance of amorphous silicon solar cell has been studied using the textured ZnO film as a front electrode. It was found that: (1) using the textured ZnO film as an amorphous silicon solar cell front electrode, it can be improved the open voltage, but the fill factor and conversion efficiency was depraved; and (2) inserting a protocrystalline silicon buffer layer between ZnO and p-a-SiC:H, the performance of solar cell was improved obviously. For example, its conversion efficiency increases from 7.3% for the SnO2: FTCO to 7.9% for the ZnO/pc-Si:H TCO.

The aim of this study is to show the influence of temperature on the relative value of the short-circuit photocurrent density obtained from an n+-p-p+silicon solar cell front illuminated with modulated polychromatic light. The solar cell was already subjected to charged particules irradiation flux (Φp) and intensity (kl,) and remained under both magnetic field (B) and temperature (T). Thus, the graphical representation of the relative value of the short-circuit photocurrent density as a function of the square of the magnetic field (B) yields to determine the slope, which is related to the mobility of minority carriers in the base. It is obtained for a back surface field silicon solar cellunder both temperature and irradiation flux of charged particules.
