NOVELTY - Photovoltaic glazing assembly (10) includes gas space located between first and second substrates (11, 12), and having a thickness T of 0.01-0.095, preferably 0.01-0.08 inch to facilitate heat transfer across the gas space, to restrain loss of photovoltaic efficiency due to temperature increases of photovoltaic coating, where gas space is the glazing assembly's only interpane space; and peripheral seal system (13) located between first and second substrates, and comprising contiguous first and second seals, each connecting the first and second substrates together along their peripheries.    USE - Photovoltaic glazing assembly.    ADVANTAGE - The assembly has extremely narrow gas space across which heat can be transferred relatively freely, where heat transfer preferably lowers the temperature of the photovoltaic coating, and lowering the temperature of the photovoltaic coating will increase the efficiency of the coating, thus, lowering the cost per unit output of power. The seal system seals the gas space from an external environment. It greatly reduces the amount of gas that crosses it into or out of the gas space.    DETAILED DESCRIPTION - Photovoltaic glazing assembly (10) comprises:    (1) first substrate (11) formed of light transmitting material, and second substrate (12), each of the first and second substrates having first and second major surfaces (121, 122), each second surface having central region and periphery, where second surfaces face each other and are parallel;    (2) temperature-sensitive photovoltaic coating over the central region of second surface of the first or second substrate, where photovoltaic coating has photovoltaic efficiency that decreases with increasing temperature;    (3) gas space located between the first and second substrates, and having a thickness T of 0.01-0.095, preferably 0.01-0.08 inch to facilitate heat transfer across the gas space, to restrain loss of photovoltaic efficiency due to temperature increases of the photovoltaic coating, where gas space is the glazing assembly's only interpane space; and    (4) peripheral seal system (13) located between the first and second substrates, and comprising contiguous first and second seals, each connecting the first and second substrates together along their peripheries, where first seal has a width (W1) and a thickness (t) that provide W1/t ratio of greater than or equal to 2, preferably greater than or equal to 4.    An INDEPENDENT CLAIM is included for a method of making a photovoltaic glazing assembly.    DESCRIPTION OF DRAWING(S) - The drawing is a perspective view of photovoltaic assembly.
