METHOD AND DEVICE FOR PRODUCING A PHOTOVOLTAIC ELEMENT WITH STABILISED EFFICIENCY
20210057600 · 2021-02-25 · ·

There are provided a method for producing a photovoltaic element with stabilised efficiency, and a device which may be used to carry out the method, for example in the form of a specially adapted continuous furnace. A silicon substrate to be provided with an emitter layer and electrical contacts is thereby subjected to a stabilisation treatment step. In that step, hydrogen, for example from a hydrogenated silicon nitride layer, is introduced into the silicon substrate, for example within a zone (2) of maximum temperature. The silicon substrate may then purposively be cooled rapidly in a zone (3) in order to avoid hydrogen effusion. The silicon substrate may then purposively be maintained, for example in a zone (4), within a temperature range of from 230 C. to 450 C. for a period of, for example, at least 10 seconds. The previously introduced hydrogen may thereby assume an advantageous bond state. At the same time or subsequently, a regeneration may be carried out by generating excess minority charge carriers in the substrate at a temperature of at least 90 C., preferably at least 230 C. Overall, with the proposed method, a regeneration process in the production of a photovoltaic element may be accelerated significantly so that it may be carried out, for example, in a suitably modified continuous furnace.
