摘要： Embodiments of the disclosure are generally related to solar panel configurations. In some embodiments, the active surface area of the solar panel is increased compared to traditional flat solar cell arrays. The increase in active surface area may increase solar panel efficiency. For example, in some embodiments, a single light ray may have portions reflected onto a plurality of solar cell surfaces to provide further opportunities for light capture and conversion to electricity.

摘要： A broadband solar cell antenna includes a first solar cell layer, a first dielectric supporting layer, an antenna layer, a second dielectric supporting layer, and a second solar cell layer sequentially from top to bottom. The first and second solar cell layers are structurally identical; the first and second dielectric supporting layers are structurally identical; a monopole is a metal base copper-clad laminate in a shovel-shaped structure; a trumpet-shaped grounded coplanar waveguide (GCPW) feeding line is used; and a solar cell array forms a meta-surface structure. The broadband solar cell antenna has the features of broadband, miniaturization and low profile. The antenna layer is provided between the two solar cell layers. Solar cells on an upper surface and a back surface of the antenna can collect light in different angles. The antenna has desired radiation performance and can function as both an antenna and a solar cell.

摘要： The disclosure provides a packaging adhesive film and a photovoltaic module. The packaging adhesive film includes a planar base layer and a buffer layer, the buffer layer is arranged on a surface of the planar base layer, and the buffer layer includes a plurality of buffer parts arranged at intervals, each one of the buffer part includes a long strip-shaped protrusion, and the long strip-shaped protrusion is arranged in a position corresponding to a photovoltaic ribbon, or arranged in a position corresponding to a cell piece gap in a photovoltaic module, or arranged in a position corresponding to a position of a depression of a lap portion of a laminated photovoltaic module, or arranged in a position corresponding to a position of a depression of a lap portion of a stacked tile photovoltaic module. The packaging adhesive film is simple in structure, and as the disclosure only aims at thickening the part of the packaging adhesive film corresponding to the position where a cell piece is prone to a micro-crack, a fracture and grating breakage, compared with the thickening of the whole packaging adhesive film in the prior art, the packaging adhesive film of the disclosure solves the probability of the reliability problems such as a micro-crack, a fracture and grating breakage occur to the cell piece in the packaging and laminating process of the photovoltaic module, as well as greatly reduces the production cost.

摘要： An apparatus and method for producing a perpetual energy harvester which harvests ambient near ultraviolet to infrared radiation and provides continual power regardless of the environment. The device seeks to harvest the largely overlooked blackbody radiation through use of a semiconductor thermal harvester, providing a continuous source of power. Additionally, increased power output is provided through a solar harvester. The solar and thermal harvesters are physically connected but electrically isolated.
