This application provides a solar cell, a method for fabricating the same, and a photovoltaic module. The method for fabricating the solar cell includes boron doping on the front side of a substrate to form a borosilicate glass layer on the surface of the substrate, the borosilicate glass layer comprising a boron-rich layer; performing a first-round-etch on the back side and sides of the boron-doped substrate to remove the borosilicate glass layer on the sides and back side, respectively, and polishing the back side; removing the boron-rich layer on the front side of the substrate after the first-round-etch; sequentially forming a tunneling oxide layer and an N-type doped layer on the back side of the resulting substrate; and performing a second-round-etch on the front side of the resulting substrate to obtain the solar cell. The solar cell fabricated by this method has high yield and efficiency, and can also reduce the occurrence of leakage current in the solar cell.

This invention provides a method for dynamic capacity expansion micro-meteorological simulation of transmission lines, belonging to the field of power system technology. The method includes: extracting features from wind field simulation data under different operating conditions based on intrinsic orthogonal decomposition to obtain corresponding modes and constructing a wind field order reduction model; using wind field data from sparse monitoring points as constraints, solving for the weight coefficients of each mode using the least squares method to reconstruct the baseline wind field for the entire line; calculating and correcting the local wind field error at non-monitoring points based on the deviation between the measured wind field data from monitoring points and the reconstructed baseline wind field, thus obtaining the wind field for the entire line; identifying dynamic thermal bottleneck points and determining the maximum allowable current carrying capacity based on the wind speed at these bottleneck points. Beneficial effects: Through offline physical cost reduction, online sparse reconstruction, and residual correction, a limited number of monitoring points can accurately invert the complex wind field of the entire line, achieving low-cost, high-precision micro-meteorological spatiotemporal simulation of transmission lines and improving the safety margin for dynamic capacity expansion.

The utility model relates to the technical field of step protection, and discloses an active stair step external corner protection device which comprises a concrete step, the upper end of the concrete step is fixedly connected with a step plastering layer, the upper end of the concrete step is further connected with a protection block, the upper end of the step plastering layer is provided with a porcelain tile strip, and the porcelain tile strip is connected with the concrete step. Auxiliary notches are formed in the two sides of the porcelain tile strip, and a drainage groove is formed in the upper end of the porcelain tile strip. According to the principle of counter-acting force of the ends of the porcelain tiles, the hard porcelain tiles are used for resisting and counteracting treading acting force of daily people passing through the steps, the phenomena that disturbance happens to the ends of the stair steps, and local edge missing and corner falling are caused are effectively avoided, and meanwhile the device is economical, practical, convenient to construct and capable of improving the construction efficiency. And the step surface taking the porcelain tile as the carrier can achieve the value-added effect of integral tiling of the step, so that the ceramic tile has good economic benefits and social benefits, is good in application prospect and is worthy of popularization.

The utility model discloses a tobacco packaging coding positioning device, including coding machine body, fixed mounting the belt conveyor of coding machine body work table, fixed mounting industrial computer all -in -one on the coding machine body stand, the both sides symmetry of belt conveyor are equipped with the side plate, and the side plate fixed mounting is in the worktable of coding machine body, and the outer surface one side of two the side plate all fixed mounting has the cylinder, and the movable end of two the cylinder all is set up and is fixedly connected with pressure detection subassembly, and the detection end of two pressure detection subassembly all fixed mounting has the sliding seat. In the utility model, through cylinder drive sliding seat and rubber belt dynamic clamping cigarette, cooperate photoelectric detection subassembly real -time trigger positioning action, need not manual or mechanical loading time strict centering, solved the accurate centering of the problem of the existing linear type full restraint guiding, improves loading efficiency, and avoids the cost investment of additional visual positioning system.

This utility model discloses a smart host and a smart wearable device. The smart host includes: a base; a host body disposed on the base; a rotating component disposed at one end of the base; a camera component rotatably disposed at the end of the host body away from the rotating component; and a quick-release component, which includes a first latching part, a second latching part, and an unlocking component. When the host body is stacked on the base, the first latching part and the second latching part are adapted to latch, so that the host body and the base remain relatively fixed. When the unlocking component drives the second latching part to disengage from the first latching part, the host body can rotate relative to the base by a preset angle. In this utility model, the host body can be quickly disassembled to achieve rotation, and the shooting direction can be easily adjusted. A single camera can meet the needs of multi-directional shooting, significantly improving the convenience of taking photos and selfies.
