Some dust particles are blocked and accumulated at the sharp edges of the vacuum chamber, which will affect dust removal efficiency. To avoid an accumulation of the dust particles in the collector, the sharp edges of the vacuum chamber are modified into round edges with a 0.4 mm radius, as shown in Fig. 9 (a).
Li et al. conducted a study on the impact of vacuum on the heat loss of flat plate PV/T collectors. The findings revealed that as the air pressure decreased, the heat loss was significantly reduced. Specifically, when the air pressure is reduced to 0.1 Pa, the convective and conductive heat losses can be reduced by over 97 %.
