TL;DR: In this paper, the electrical efficiency effects of naturally forming atmospheric dust deposits on commercial photovoltaic panels were investigated and a mathematical model was developed to determine maximum potential as a function of temperature and of total incident radiation.

TL;DR: In this article, the heat transfer by natural convection and surface thermal radiation in a tilted 2D open cavity is presented, and the results in the steady state are obtained for a Rayleigh range from 104 to 107 and for an inclination angles range of the cavity from 0° to 180°.

TL;DR: In this article, a numerical study of the transient and steady-state heat transfer and air flow in a horizontal square open cavity is presented, where the flow is laminar, the fluid is radiatively nonparticipating, and Boussinesq approximation is valid.

TL;DR: In this paper, the effect of the surface thermal radiation in tall cavities with turbulent natural convection regime was analyzed and quantified numerically, and it was shown that the surface radiation does not modify significantly the flow pattern in the cavity, just negligible effects in the bottom and top of the cavity were observed.

TL;DR: Theoretical efficiencies and thermal behavior of all-glass Evacuated Tube solar Collectors with an Internal Absorber Film (ETCIAF) are compared and contrasted with the traditional design of allglass ETCEAF, using the absorber film on the external surface of the inner tube as discussed by the authors.
