In case of the voltaic pile, the negative electrode is the zinc plate, which is the contact where the oxidation reaction occurs and electrons flow out. The positive electrode is the copper plate since this is the contact where the electrons flow in and the reduction reaction occurs.
All-back-contact (ABC) architectures have the potential to outperform conventional counterparts. Electrodes with smaller pitch sizes improve charge collection in BC-PSCs. Interdigitated back-contact (IBC) electrode configuration is a novel approach toward highly efficient Photovoltaic (PV) cells.
Since the direction of the current is opposite to that of the electron flow, the electrons move from the negative electrode of the dry battery toward the positive electrode. In case of the voltaic pile, the negative electrode is the zinc plate, which is the contact where the oxidation reaction occurs and electrons flow out.
Silicon-based solar cells are an important field for the development of the photovoltaic industry. The grid electrode on the front surface of the traditional silicon solar cell causes shading loss.
The market-dominating silicon solar cell is a pn junction with a thin highly-doped n-layer, the front, light-admitting electrode, on a p-type substrate. Light entering at the n-layer is partially absorbed in the diffusion layer adjacent to the depletion region that separates the photocharges, as well as in the p-layer behind the junction.
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.
