Using solar panels is one of the cleanest ways to generate electricity ever created by mankind. The efficiency of rapidly expanding solar panels decreases during their lifetime for several reasons, such as photodegradation, hot spots, potentially induced degradation, etc. Dirt and debris accumulation on the surface of the solar panels can also significantly contribute to their performance degradation due to the diminishing of the solar radiation reaching their active surfaces. Numerous degradation mitigation methods are cited in the literature. This article briefly outlines these basic measures.

“…Furthermore, in the automotive and aerospace industries, AMmanufactured lightweight components are used to reduce weight and lead times [6]. In the field of electronics, optimized components can be realized with AM to meet the demand for smaller but more powerful devices [7]. For example, optimized heat sinks with a high surface-to-volume ration [8] or integrated cooling channels [9] can be manufactured using AM leading to improved heat dissipation, which increases the efficiency and longevity of those components.…”

With the increasing demand for customized products, new requirements on production processes are set. Additive manufacturing with its tool-independent character shows great potential to replace conventional manufacturing processes. This also applies to power electronic assemblies, which are currently produced with a low variety of variants in large batches. However, high-quality processing of copper is a prerequisite for power electronics applications in order to achieve low power losses and long module lifetimes. Green high-power lasers show great potential to process pure copper powder by means of powder bed fusion using a laser-based system (PBF-LB/M) and open up new opportunities in power electronics production. PBF-LB/M not only facilitates the production of mono-material components such as load connectors or heat sinks but also provides multi-material capabilities, enabling 3D metallizations on ceramic substrates for use as power electronic circuit carriers. Therefore, parametric studies on the fabrication of copper metallizations via PBF-LB/M on alumina substrates using a 1 kW green laser have been conducted and are summarized in this paper. At first, the beam-matter interaction between preheated alumina substrates and parameterized laser radiation was analyzed. Based on the results, process parameters have been defined, which were then used for the production of copper metallizations. High temperature preheating of the ceramics was applied in order avoid delamination effects due to thermomechanical stresses during solidification. In parametric studies with respect to laser power, laser velocity and hatching distance on 500 °C preheated substrates, electrical conductivities of 30 MS/m and shear strengths of 69 MPa were obtained.
