Streszczenie:
In this work, we propose a new method for manufacturing
busbars in photovoltaic modules for different solar cell generations, focusing
on 1st and 3rd generations. The method is based on high-pressure spray
coating using nanometric metallic powder. Our focus is primarily on opti-
mizing conductive paths for applications involving conductive layers used in
3rd generation solar cells, such as quantum dot solar cell, dye-sensitized so-
lar cell, and silicon-based solar cells on glass-glass architecture for building integrated photovoltaic. The advantages of the proposed method include
the possibility of reducing the material quantity in the conductive paths
and creating various shapes on the surface, including bent substrates.
This paper examines the influence of the proposed high-pressure spraying
technique using metallic particles on the morphology of the resulting conduc-
tive paths, interface characteristics, and electrical parameters. Conductive
paths were created on four different layers commonly used in photovoltaic
systems, including transparent conductive oxide, Cu, Ti, and atomic layer
deposition processed Al2O3. The use of high-pressure technology enables
the production of conductive layers with strong adhesion to the substrate
and precise control of the spatial parameters of conductive paths. Further-
more, the temperature recorded during the deposition process does not ex-
ceed 385 K, making this technique suitable for various types of substrates,
including glass and silicon. Additionally, the produced layers exhibit low
resistance, measuring less than 0.3 Ω. Finally, the mechanical resistance, as
determined through tearing tests, as well as environmental and time stabil-
ity, have been confirmed for the produced paths.
