Characterization of Solar Cell Busbar Grid for Different Technologies by Time Domain Reflectometry Simulation: Transmission Line Approach

This work electromagnetically simulates the design of metallic grids for different Busbar technologies in standard solar cells existing in the photovoltaic market in order to characterize their grid impedance using a signal integrity technique known as Time Domain Reflectometry - TDR and addressing the design of metallized grid of solar cells within the foundations of transmission lines. The objective of the investigation is to parameterize the results obtained so that they can serve as a reference in studies of micro-resistance in series of solar cells and their effects on energy efficiency.
