Sensor module for concentrated photovoltaic (CPV) technologies using a point-focusing glass Fresnel lens, whose sensor housing (1) is designed as a straight truncated square pyramid, where in an implemented sensor module, has, on its side surfaces facing north, south, east and west, photoresistors (3) with reduced active surfaces (4) as indirect radiation detecting photosensors. At the top of the sensor housing (1), a focal pinhole (8) is formed centrally, and the direct sunlight detecting lens (6) is centrally connected to the top of the sensor housing (1) via a spacer element (7) made of opaque material, the optical axis of which coincides with the longitudinal axis of the sensor housing (1) and the center of the focal pinhole (8).  The optical focal point (10) of the lens (6) coincides with the focal pinhole (8) in the plane of the top of the sensor housing (1) and coincident with the optical axis of the lens (6) inside the sensor housing (1). The central photosensor (9) is arranged at a distance to the optical focus point (10) of the lens (6), therefore it is not damaged by concentrated direct radiation. When the focal pinhole is located, the direct radiation falling on the photosensor stops the sun tracking exactly, while the CPV cells deliver the maximum power. The electrical output of the photosensors (9) is connected to the control unit used in current photovoltaic technology. 

This light-guiding component for a lighting fixture comprises a small, gently sloping entrance section in the shape of a truncated square pyramid and a larger, more steeply sloping tapered section also in the shape of a truncated square pyramid. The constricted section between the tapered section and the lens section (described below) is narrowed from the square base of the tapered section to its inscribed circle, with the lens section being integrated into the constricted section. This component maximizes light from a light source, such as a light-emitting diode, through the entrance section, guiding the light from the bottom of the tapered section to the circularly constricted illumination surface, and projecting a circular beam of uniform illuminance onto the front surface through the lens section. While light-guiding components for lighting fixtures consisting of a small, gently sloping entrance section in the shape of a truncated cone and a larger, more steeply sloping truncated cone have not been able to achieve circular illumination with uniform illuminance, this component achieves circular illumination with uniform illuminance throughout the entire circle. In the reference diagram showing the state of use, the product is depicted in blue, but in reality the entire product is a solid, transparent body.

The invention discloses a p-type Pavonite thermoelectric material with low thermal conductivity and a preparation method and application of the p-type Pavonite thermoelectric material. The chemical formula of the p-type Pavonite thermoelectric material with low thermal conductivity is MnSnSb4Se8, and the chemical formula of the p-type Pavonite thermoelectric material with low thermal conductivity is MnSnSb3.98 Se8 after regulation and optimization of Sb vacancy. The crystal structure of the p-type Pavonite thermoelectric material with low thermal conductivity is composed of a NaCl configuration layer with an adjustable thickness and a GeS configuration layer with an unadjustable thickness. The NaCl configuration layer and the GeS configuration layer are connected through a shared Se atom; in the NaCl configuration layer, octahedrons formed by [Sn / MnSe6] and [SbSe6] are connected in a common edge manner; the GeS configuration layer is composed of two [SbSe5] tetragonal pyramids and two [Sn / MnSe6] octahedrons; the method is easy to operate, a large amount of MnSnSb4Se8 with high phase purity can be obtained within a short time, and the thermoelectric figure of merit of the MnSnSb4Se8 can reach 0.23 under 823K; through Sb vacancy regulation and control, when the vacancy concentration is 0.02, the thermoelectric figure of merit of MnSnSb3. 98Se8 under 823K can be increased to 0.32, and is increased by 39% compared with intrinsic thermoelectric figure of merit of MnSnSb3. 98Se8.

This invention discloses a multi-constraint parameter satellite stealth optimization configuration, belonging to the field of satellite configuration design. The multi-constraint parameter satellite stealth optimization configuration is a teardrop-shaped stealth satellite configuration. The external frame of the configuration is a teardrop-shaped structure formed by truss combinations and interconnected triangular configuration parts. The top octagonal pyramid structure, octagonal frustum structure, octagonal pyramid structure, and square pyramid structure are all truss structures. The configuration minimizes strong scattering, and the smooth structure reduces specular reflection, thus exhibiting excellent stealth characteristics. The RCS characteristics are very good, meeting the stealth requirements of stealth satellites: in the dangerous band, the RCS is below -10dB within ±30° of the nose cone incident angle. The circumferential RCS value is kept as low as possible. Load-bearing plates, load-bearing rods, and supporting stiffeners are added to the structure to meet mechanical constraints: the satellite structure has sufficient stiffness, strength, and stability. The heater power and heat dissipation device mounting positions are determined to meet the satellite's thermal constraints.
