Abstract: The invention provides a method of producing a stabilized photoconducting semiconductor film by electroplating onto a cathode body. The fnmis of amorphous silicon containing hydrogen. A solution (16) of a halogenated silane, and/or silicon halide, in an aprotic solvent containing a tetrabutylammonium salt is slectroysed, in a nitrogen atmosphere, using a platinum anode (20) and nichrome cathode (26). The plated cathode is removed to a nitrogen-containing chamber (128), and the chamber purged with helium or hydrogen. Cathode (26) is then removed to a heating chamber (30) and heated in the presence of helium or hydrogen at above 250°C, preferably 350°C for thirty minutes. The silicon film is thereby stabilized chemically and physically. Subsequently, a pellucid layer of high work function, for example of platinium, iridium or palladium, can be deposited on the thus stabilized film to produce a photovoltaic device.

Abstract: A process and device for selectively separating particles from a suspension is disclosed. The process involves: introducing the suspension into a rotating separation chamber in which the flow is regulated so that the angular velocity of the suspension is maintained slightly higher than the angular velocity of the wall of the chamber. The bulk of the flow of the suspension treated is removed from the separation chamber from a peripheral area. The following fractions are removed separately, simultaneously, and if necessary continuously. The heavy fraction is removed from a zone near of the sidewall; the light fraction is removed from a zone nearer of the longitudinal axis of the chamber, than the heavy fraction outlet and if desired, an intermediate fraction may be removed from at least one separate intermediate zone between the light fraction outlet and the heavy fraction outlet. The apparatus comprises a separation chamber having a longitudinal axis, sidewalls and two ends; inlets through the first end for introducing suspension and auxiliary fluid; rotating means for deviating suspension and auxiliary fluid towards the sidewalls outlets for the heavy and the intermediate fractions in the second end of the separation zone; rotating means to collect the effluents from areas nearer the sidewalls to their respective outlets; and a light fraction outlet is provided in the first end of the separation chamber and is colinearly aligned with the longitudinal axis. Rotating means are provided to rotate the separation chamber around its longitudinal axis. Numerous alternative embodiments are described.

La radiation laser est choisie avec une longueur d'onde passant au travers de la couche a dopage p + (6) sans absorption. Lorsque la radiation laser est absorbee dans la couche a dopage n, la chaleur produite diffuse le dopant p depuis les deux couches adjacentes pour convertir la region exposee en type p. Au fur et a mesure que s'effectue le balayage du rayon laser, il se forme une bande ayant une jonction avant pn pour une action laser.
