    Abstract: A light weight photovoltaic device for use in stratospheric and outer space applications. The device includes a protective surface coating on the light incident side thereof. The protective coating does not deleteriously affect the photovoltaic properties of the solar cell, is formed of a material which protects said solar cell from the harsh conditions in the stratospheric or outer space environment in which the photovoltaic device is adapted to be used; and remains substantially unchanged when exposed to the harsh conditions in the stratosphere or outer space. The protective coating is preferably made of a spray coated silicone based material and is between 0.01 and 2 mil thick.
