The invention concerns a transparent conductive film based on indium, tin and germanium oxides (ITGO), a product comprising a substrate at least partly covered with such a conductive film and capable of further including a silicon layer on said film, and a method for making such a product. In the inventive film, the ratio of concentrations by weight of SnO2/GeO2 ranges from 1 to 10. Said film is transparent in the infrared window, that is 0.3 to 3 mu m and has a reflectivity of more than 80 %.
