Solar car sunscreen

The invention discloses a shading hood for a solar energy automobile. The shading hood comprises a framework, sun cloth and a solar cell panel, the solar cell panel is installed at the upper side of the middle of the framework, and the sun cloth is fixed to the periphery of the framework; semiconductor chilling plates are distributed inside the sun cloth, and a concentrator or a controller is arranged at the bottom of the framework and used for being connected with the semiconductor chilling plates and driving the semiconductor chilling plates to work. By means of the shading hood, the shading effect and the cooling effect can be achieved simultaneously. Solar energy over an automobile body can be transformed into cooling capacity, and an equivalent effect that the illumination area is reduced is achieved. The heat energy is transformed into the cooling capacity, so that the temperature within the automobile body area is obviously lower than that in surrounding areas. The sun cloth serves for shading from the sun and is capable of maintaining the cooling capacity from being leaked outward. According to the shading hood, the universality is great, the installation and dismounting of the framework are convenient, the entire size after the shading hood is compressed is small, the shading hood can be stored in a trunk of the automobile body, and the use is quite convenient. Rubber bodies can be assembled into elastic clamping seats, so that the shading hood can be fixed to sunken areas at the upper edged of automobile windows in a clamped mode. The shading hood is reasonable in structural design, quite ideal in trial application effect and suitable for being implemented and popularized.

A cmos APD optoelectronic device with low dark current

ActiveCN112635613BGuaranteed detectableGuaranteed detectabilitySemiconductor devicesCapacitancePhotocurrent
The invention claims a CMOS APD photoelectric device with low dark current, which belongs to the field of semiconductor photoelectric devices. The device structure includes a P substrate, which also includes a P well on which ions are implanted, and the ion implantation on the P well has one N+ layer and two P+ layers, the N+ layer is a cathode, and the P+ layer is an anode. The heavily doped N+ layer and the lightly doped P well layer form a PN junction, that is, an avalanche region is formed, and an illumination window is set. When the light source enters the device and is absorbed by the light absorption region, photogenerated carriers are generated. Carriers move to the avalanche region under the action of an electric field to participate in multiplication; the two ends of the gap of the P well layer are also doped with STI guard rings and the two sides of the N+ layer are doped with small-sized STI guard rings. The reasonable setting of STI can ensure The reduction of the dark current can also enable the photocurrent to be detected effectively; the photoelectric effect and capacitance are optimized in the design of the device electrode. This design technology is designed from three aspects: PN junction, STI guard ring, and electrode setting to reduce the dark current of the device, ensure that the photocurrent can be detected, and the capacitance is reduced.
