Tenders are invited for High Specific Power Photovoltaic Assembly Components and Modules (Artes at 4f.174) - Expro+ Re-Issue Objective: The objective of this activity is to design, manufacture and test thin solar cells, a photovoltaic assembly (PVA) module of very high specific power (140 W/kg) and develop new processes for solar cell thinning, welding, laydown.Targeted Improvements:Doubling the specific power of the state-of the art photovoltaic assembly with standard rigid solar arrays (benchmark 60-70 W/kg) Description: In recent years, flexible solar arrays have become more popular as they enable lighter and thinner structures and solar cells. However, the current technology for the rest of thephotovoltaic assembly, such as protective shielding, diode, cell interconnection and suitable interconnection solutions, compatible with the necessary low mass and flexibility requirements, are not yet available.This activity will design, manufacture and test thin solar cells, a photovoltaic assembly (PVA) breadboard of very high specific power (140 W/kg) and develop new processes for solar cell thinning, welding and lay down. This includes lift-off and handlingprocesses of thinned solar cells as well as solutions for interconnection of solar cells and welding technologies allowing for embedding shielding material into a laminate. Different innovative PVA concepts based on low mass and flexible technologies will be investigated,breadboarded and tested.Read more Tender Link : https://esastar-publication-ext.sso.esa.int/ESATenderActions/filter/open
