Abstract
Abstract An encapsulated photovoltaic solar cell assembly comprising at least one solar cell mounted and hermetically sealed in a substantially rigid, elongated, tubular envelope which is transmissive to actinic radiation to which the photovoltaic solar cell is sensitive. The assembly can include an antireflection coating for reducing the reflection of solar radiation from the envelope as well as reflective coatings for uniformly distributing solar radiation over the light gathering surfaces of the cell.
