The surface recombination velocity of a silicon sample is reduced by deposition of a thin hydrogenated amorphous silicon or hydrogenated amorphous silicon carbide film, followed by deposition of a thin hydrogenated silicon nitride film. The surface recombination velocity is further decreased by a subsequent anneal. Silicon solar cell structures using this new method for efficient reduction of the surface recombination velocity is claimed.

This invention relates to a method for producing solar cells, and photovoltaic panels thereof. The method for producing solar panels comprises employing a number of semiconductor wafers and/or semiconductor sheets of films prefabricated to prepare them for back side metallization, which are placed and attached adjacent to each other and with their front side facing downwards onto the back side of the front glass, before subsequent processing that includes depositing at least one metal layer covering the entire front glass including the back side of the attached wafers/sheets of films. The metallic layer is then patterned/divided into electrically isolated contacts for each solar cell and into interconnections between adjacent solar cells.

A crystalline silicon ingot is produced using a directional solidification process. In particular, a crucible is loaded with silicon feedstock above a seed layer of uniform crystalline orientation. The silicon feedstock and an upper part of the seed layer are melted forming molten material in the crucible. This molten material is then solidified, during which process a crystalline structure based on that of the seed layer is formed in a silicon ingot. The seed layer is arranged such that a {110} crystallographic plane is normal to the direction of solidification and also so that a peripheral surface of the seed layer predominantly also lies in a {110} crystallographic plane. It is found that this arrangement offers a substantial improvement in the proportion of mono-crystalline silicon formed in the ingot as compared to alternative crystallographic orientations.
