NOVELTY - The back contact solar cell has primary interdigitated metallization pattern that is positioned on backside of semiconductor substrate. Backplane is attached to backside of substrate, and is provided to support substrate. Secondary interdigitated metallization pattern is positioned on backplane, and is connected to primary interdigitated metallization pattern. On-cell electronic component is attached to secondary metallization pattern, and is provided with bypass switch (50). Electrical leads (52) connects on-cell electronic component to secondary metallization pattern.    USE - Back contact solar cell, for solar photovoltaic (PV) module (claimed) such as crystalline silicon PV modules and non-crystalline silicon PV modules such as cadmium telluride PV modules, copper indium gallium selenide (CIGS) PV modules and amorphous silicon PV modules.    ADVANTAGE - Since emitter and base interconnection leads are available on the backsides of the cells, the overall implementation of on-cell electronics is simplified for enhanced energy harvesting, additional cell-level monitoring and control functions. Cell/module monitoring leads to improved servicing, cleaning, performance, forecasting and preventive maintenance actions. The improved inverter reliability manages voltage and current to predictable levels so as to remove stress on the centralized inverter and improves overall conversion efficiency. The centralized inverter design can be simplified and cost reduced as a result of the truly distributed cellular maximum power point tracking (MPPT) power optimization solution. Automatic shut-off for emergencies and easier and safer installations and maintenance are achieved. Shading and design flexible string lengths and planes are ignored, so that less expensive system of design analyses and cheaper overall installation costs are achieved. Since one bypass switch is used for a cell, the entire module can be wired as a single string of all the cells within the module connected in series. The solar cell backplane with both polarities of the solar cell on the backplane can be effectively used to electrically assemble and integrate electronic components on the cell backside backplane, without obstructing the sunny side of the solar cell and without degrading the reliability of the solar cell. Thus enables implementation of distributed shade management with enhanced energy yield, distributed cell-based MPPT power optimization, reduced levelized cost of electricity (LCOE), and improved photovoltaic system reliability through smarter electricity management. The backplane enables for direct mounting, attachment and support of the thin-format electronic components on the solar cell. The backplane enables for effectively decouples from the sensitive solar cell without detrimental stress effects of the components and attachments. The power electronics components are low cost. The fabrication of PV modules from mismatched cells with different binning parametrics is enabled. The effective cost of per watt of manufactured modules is reduced by distributed maximum power point tracking.
