NOVELTY - A solar cell package, comprises a solar cell having an active surface; and a coating applied to the active surface of the solar cell. The coating comprises a four-layer structure including a first nickel chromium nitride layer (402) with a thickness of 5-15 Angstrom ; a silver layer (404), containing at least 99.999% Silver with a thickness of 40-100 Angstrom , applied to the first layer; a second nickel chromium nitride layer (406) with a thickness of 5-15 Angstrom , applied to the silver layer; and a silicon nitride layer (408) applied to the second nickel chromium nitride layer.    USE - As solar cells, including triple junction cell, silicon cell (claimed), photovoltaic cells for converting sunlight to power.    ADVANTAGE - The durable silver based thin film vacuum deposited coatings, acts as an anti-reflection coating on various substrates, are electrically conductive, and provide high transmission across extremely wide-bandwidths. The coatings are environmentally durable and are more electrically conducting than other types of coatings. The coating can be used on various solar cell substrates to replace the solid metal films now used to gather the current, and improve the efficiency of solar cells. The coating has very broadband, from at least 350-1500 nm, antireflective properties, especially in the ultraviolet (UV) and visible wavelengths, and is electrically conductive. The coating is environmentally durable, and will pass humidity tests, acid baths and sulfur dioxide exposure. The coating forms film that allows elimination of some or all of the metal contacts on the cell face, anti-reflect the cell surface, improves transmission, and increases cell efficiency. The coating is transparent, electrically conductive, and does not shadow the surface of the cell as the nominal used thick metal does. The coating is based on durable silver, which does not degrade when used in harsh environments. The coating does not require heated substrate temperatures to apply, and is bendable when deposited on plastic substrates.    DETAILED DESCRIPTION - A solar cell package, comprises a solar cell having an active surface; and a coating applied to the active surface of the solar cell. The coating comprises a four-layer structure including a first nickel chromium nitride layer (402) with a thickness of 5-15 Angstrom ; a silver layer (404), containing at least 99.999% Silver with a thickness of 40-100 Angstrom , applied to the first layer; a second nickel chromium nitride layer (406) with a thickness of 5-15 Angstrom , applied to the silver layer; and a silicon nitride layer (408) applied to the second nickel chromium nitride layer. The first nickel chromium nitride layer is applied to the active surface. The solar cell package further comprises at least one via that electrically connects the first and second four-layer structure; an additional silicon nitride layer adjacent to the second four layer structure; and additional five-layer structure or sixteen-layer structure. The via is below a busbar. An INDEPENDENT CLAIM is included for creating a solar cell package, involving obtaining a solar cell having an active surface; and applying the coating to the active surface of the solar cell.
