  • Patent number: 11978811
    Abstract: A solar cell covered with a transparent plate through a predetermined gap includes a flexible power generating layer which photoelectrically converts light incident thereon through the transparent plate, a resin layer covering a light receiving surface of the power generating layer, and an adhesion preventing layer covering the surface of the resin layer and facing the transparent plate through the gap. The adhesion preventing layer is made of an inorganic material and has a surface roughness Sz of 1 nm or more and 500 nm or less. Thus, the outermost surface of the solar cell is constituted by the adhesion preventing layer, so that no tack mark occurs even when partial contact occurs between the solar cell and the transparent plate which face each other through the gap. As a result, it is possible to prevent deterioration in appearance due to the tack mark.

  • Patent number: 11888444
    Abstract: Photovoltaic thermal (PVT) apparatus 10 combines a photovoltaic panel (PV) panel 24 and solar air heater (SAH). The SAH includes body 12 with hollow interior 14 defining ducts 16a, 18a for air inlet 16 and air return 18. Jets 22 provide air to convey heat from the PV panel underside. Spaces between the jets provide drains 26 for warmed air to flow away. Flow modifiers/deflectors 124 can guide the airflow. A fan 42 pushes ambient air into the inlet 16 via air handling unit (AHU) 50. Return warm air flows via the AHU to escape via the ambient exhaust 40. A combined thermal transfer and storage unit 52 determines whether air from the PVT panel(s) diverts to the interior space. For cooler ambient conditions, the PVT apparatus can radiate heat to return cooled air into the space. The PVT apparatus can harvest condensation, heat/cool pools and industrial processes.
