Temperature Limitation in Evacuated Solar Collector Tubes [PDF]

open access: yesAustralian Journal of Physics, 1987
A recent innovation in evacuated tubular solar collector technology is described. A desorbable gas, which specifically adsorbs on the graphitic solar selective surface, can reversibly degrade the vacuum by providing a heat conduction path at elevated temperatures. The stagnation temperature of the system is thus limited in a controllable manner without
