Abstract: In order to reduce the top heat loss of the flat-plate solar collector and improve the thermal efficiency of the collector,
the transparent cover plate of the top structure was selected to optimize according to the flat-plate solar collector structure. This
paper summarized the progress of the cover plate's optimization in recent years, including selection of cover plate material, coating
technology for the cover plate surface, a variety of different forms of the cover plates and the cover plate combined with highquality
insulated solid material silica aerogel. These optimization measures are to achieve the purpose of optimization by changing
the heat insulation, light transmission and reflection of the transparent cover plate. Finally, it looked forward to the optimization
development direction of transparent cover plate in the future.
