Interdigitated back-contact (IBC) electrode configuration is a novel approach toward highly efficient Photovoltaic (PV) cells. Unlike conventional planar or sandwiched configurations, the IBC architecture positions the cathode and anode contact electrodes on the rear side of the solar cell.

Most efficient solar panels 2024 — Clean Energy Reviews

Solar Cell Efficiency Explained. Cell efficiency is determined by the cell structure and type of substrate used, which is generally either P-type or N-type silicon, with N-type cells being the most efficient. Cell efficiency is calculated by what is known as the fill factor (FF), which is the maximum conversion efficiency of a PV cell at the optimum operating voltage and
