Photoelectric composite material and preparation method thereof

Abstract

The invention discloses a photoelectric composite material and a preparation method thereof. The photoelectric composite material comprises a high-temperature-resistant protective layer and a substrate base material, wherein the high-temperature-resistant protective layer is installed at the upper end of the substrate base material, a lower ohmic contact layer is arranged at the upper end of the high-temperature-resistant protective layer, and a lower limiting layer is arranged at the upper end of the lower ohmic contact layer. The high-temperature-resistant protective layer is additionally arranged between the traditional photoelectric composite material and the substrate base material, due to the fact that a main body of the photoelectric composite material is a laser material, and the high-temperature-resistant protective layer is additionally arranged between the laser material and the substrate base material, the substrate base material and the laser material can be protected when the laser material is manufactured and normally used, the high-temperature-resistant protective layer has excellent high-temperature-resistant performance, under the influence of high temperature, the high-temperature-resistant protective layer can protect the laser material from being separated from the substrate base material, so that the service life of the whole laser material after being mounted on the substrate base material can be prolonged, and the use stability of the whole laser material can be improved.
