A solar cell comprising a substrate on which grooves are formed on the from and back sides thereof. The grooves on the front side are disposed in order to inscribe an angle with respect to the grooves on the back side. The intersection of the grooves on the from side and the back side form a plurality of through holes which form a grid pattern. Also disclosed is a method for producing a flat component with a grid of through holes (7). To produce the through holes (7), a plurality of generally equidistant, parallel V-shaped grooves (8) are formed on the from and back sides of a wafer. The grooves (8) on the two sides inscribe an angle relative to one another and are sufficiently deep for the through holes (7) to be automatically created at the intersections of grooves (8). The method is suitable for producing high efficiency solar cells.
A method for producing a solar cell comprising a semiconductor substrate in which the energy of incident rays generates charge carriers, the semiconductor substrate having contact zones with electric contacts for collection of charge carriers, comprising the step of:
A method for metallizing a solar cell comprising a semiconductor substrate having front and back sides in which charge carriers are generated by incident ray energy, the semiconductor having grooves on the front and back sides of the semiconductor substrate, comprising the steps of:
A Solar cell in which charge carriers are generated by the energy of incident rays, which charge carriers are separated by an electrical field and thereafter collected via electrically conducting contacts, comprising:
