Minority carrier recombination is studied in multicrystalline ingot cast silicon solar cells. The normalized recombination strength Γ of dislocations is obtained by correlating topograms of the… Continue Reading
The influence of an annealing step at about 500 degree celsius after emitter diffusion of multicrystalline solar cells is investigated. Neighboring wafers from a silicon ingot were processed using ...
An analysis of the nucleation mechanism of pyramids formed in (100) silicon in Na2CO3/NaHCO3 solution has been carried out. This texturization process of silicon by means of Na2CO3/NaHCO3 solutions… Continue Reading
In this work, a novel diluted carbonate/bicarbonate solution was applied for texturization of monocrystalline silicon for solar cells. The content of reactants in the solution was decreased 20 times… Continue Reading
Abstract In this work we have applied the X-ray photoelectron spectroscopy (XPS) in depth to study, for the first time, the influence of different thermal treatments in the ITO–Si interface of a… Continue Reading
In this work it is studied the influence of different texturizations on minority carrier lifetime of n-type Fz silicon wafers passivated with thin amorphous silicon layers (a-Si:H). For… Continue Reading
Abstract In this work the use of HF/HNO 3 solutions for texturing silicon-based solar cell substrates by stain etching and the influence of texturing on minority carrier lifetimes are studied. Stain… Continue Reading
In this work we present a cell process for amorphous crystalline silicon heterojunction (SHJ) solar cells based on process steps well known in the photovoltaic industry. All amorphous silicon layers… Continue Reading
Abstract In this work, erbium and ytterbium have been incorporated into luminescent porous silicon (PS) layers by simple impregnation of the PS substrate with a saturated nitrate solution of erbium… Continue Reading
