NOVELTY - A photovoltaic assembly comprises first substrate (11) being formed of transparent or light transmitting material, and second substrate, each substrates having first and second major surfaces; photovoltaic coating disposed over the central region of the second surface (122) of first or second substrate; and seal system (13) containing first and second seal, the seal system disposed between two substrates and joining substrates to one another, along their peripheries.    USE - As a photovoltaic assembly (claimed) in solar cell industry.    ADVANTAGE - The photovoltaic assembly provides low seal failure rates. The process reduces the amount of light-absorbing material to obtain the solar cell; reduces overall size of the devices and assemblies; enhances the efficiency in the conversion of light to electrical energy; and reduces the cost compared to the costs for bulk solar cells devices.    DETAILED DESCRIPTION - A photovoltaic assembly comprises a first substrate (11) being formed of a transparent or light transmitting material, and a second substrate, each of the first and second substrates having first and second major surfaces, each second surface having a central region and a periphery, and the second surfaces facing and spaced apart from one another; a photovoltaic coating disposed over at least the central region of the second surface (122) of the first substrate or the second substrate; and a seal system (13) containing a first and second seal, the seal system disposed between two substrates and joining substrates to one another, along their peripheries, the seal system enclosing an airspace that extends between the second surfaces of substrates and along the central regions of it, the second seal contains a composition comprising a silyl containing polyacrylate polymer alkoxysilane and a catalyst. An INDEPENDENT CLAIM is included for making a photovoltaic assembly involving forming a first and second substrate; forming photovoltaic coating over at least the central region of second surface; providing a seal system; applying the first seal to the periphery of at least one of the substrates; bringing the first and second substrates together in opposed relationship with the first seal disposed along the peripheries of it, such that an airspace is formed between the second surfaces and along the central regions of it; and applying pressure to the assembly to join the first and second substrates together such that the airspace is maintained between the first and second substrates.
