Different busbar concepts with three, four, five and six busbars (BB) on standard silicon solar cells on both full cell format (156 mm x 156 mm) and half-cell format (156 mm x 78 mm) were investigated. 40 prepared single-cell mini module specimens, five of each per variation, were tested with a flash cell tester to determine series resistance and maximum power for a relative comparison. Simulations with original measured parameters were compared to the determined values of the experiment. A dependency was found between the number of busbars and the finger grid design, all together affecting series resistance and efficiency. An optimized busbar concept with at least 4-BB technology is recommended as a first step due to performance improvement and economic issues.
