The invention relates to a method for improving the ohmic-contact behaviour between a contact grid and an emitter layer of a silicon solar cell, in which, in a treatment step, a treatment current flow having a current density of 200 A/cm2 to 20,000 A/cm2 in relation to the treatment section is induced while biasing and illuminating the silicon solar cell. The object of the invention is to improve the method for improving the ohmic-contact behaviour between a contact grid and an emitter layer of a silicon solar cell. In particular, it should be possible to quantify the improvement achieved by the method while implementing the method. Furthermore, any damage resulting from the application of unfavourable process parameters should be detected while the method is being implemented. This object is achieved in that a measurement step is carried out before and/or after the treatment step, and, in said measurement step, a measurement current flow having a current density of 1 mA/cm2 to 500 mA/cm2 is induced by illuminating the sun-facing side of the silicon solar cells and biasing, and a current strength of said measurement current flow is sensed using an ammeter and stored assigned to the respective measurement section.

An apparatus for generating electricity via thermophotovoltaic (TPV) energy conversion is described. High efficiency is obtained by introducing a material into a combustion chamber that emits bright near-monochromatic visible light upon heating. This light is then directed to fall on an array of photovoltaic (PV) cells which convert the light to electricity. Heat and infrared radiation that is not absorbed by the PV cells is returned to the combustion chamber to further improve conversion efficiency.
