The present invention relates to a silicon crystalline flexible solar cell. Silicon solar cells are largely made of amorphous, polycrystalline, and monocrystalline solar cells. Amorphous solar cells have the advantage of making large areas of thin films by low temperature deposition using glass substrates. Amorphous solar cells, which are relatively crystalline and have low flying efficiency. In addition, polycrystalline solar cell dissolves polysilicon, mixes the necessary impurities, and then pours it into a mold and gradually cools the system to make a rectangular ingot of polycrystal, and slices to a desired thickness to make a solar cell. Is a polycrystalline solar cell, and its efficiency is about 20%. The most efficient single crystal solar cell dissolves polysilicon in the chamber, mixes the necessary impurities, soaks the seeds (silicon single crystal seeds) in the dissolved silicon, and slowly rotates them through the crystallization process. The ingot is made, the wafer is made by the slice process, and the solar cell is made by the cell process. The solar cell is a single crystal solar cell, and the efficiency is about 25%.

The present invention is amorphous, solar cells, polycrystalline solar cells. Silicon crystalline flexible to process single crystal solar cell and make it flexible to make flexible solar cell, and to glue around the outer circumference of circular column, polygonal column, and make column solar cell module and tree solar cell module. It is a solar cell.

The problem to be solved in the present invention is to be able to bend the amorphous solar cell, silicon polycrystalline solar cell, silicon single crystal solar cell made on a glass substrate and to be easily attached to the cylinder with an adhesive sheet on the bowel movement.

According to the above solution, the amorphous solar cell, the silicon polycrystalline solar cell, and the silicon single crystal solar cell made on the glass substrate are cut into small cells, divided into electrically divided cells, and the wired cells are coated with transparent silicon. It is a flexible solar cell that can seal the solar cell inside the transparent silicon by molding, molding, or mold molding, and attach the adhesive sheet to the back to easily attach to the cylinder.

The solar cell made of the present invention divides the conventional amorphous, polycrystalline, and single crystal solar cells into small pieces, electrically wires them, and seals them with transparent silicon to enable warpage.

Hereinafter, the configuration and embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 shows a conventional single crystal solar cell, in which a small amount of the desired impurities are mixed in the purified polysilicon, dissolved in a chamber, slowly rotated in the dissolved silicon using a seed, and crystallized by a pulling-up process to crystallize the single crystal ingot. Then, the ingot is sliced to make a wafer, and each cell process is used to make a single crystal solar cell. Since the ingot is made circular and maximizes the size, the single crystal solar cell has a square R value at four corners in a square shape, and a solar cell having a circular R value at a corner is a somewhat disadvantageous shape in the present invention. . Figure b is a polycrystalline solar cell, which is made by melting polysilicon into a rectangular frame and gradually cooling it with a system. The wafer is sliced by crystalline ingots, and a polycrystalline solar cell is formed by each cell process. The four corners have a straight rectangular shape, which is preferable in the present invention. Therefore, in proceeding the description of the present invention, all of an amorphous thin film solar cell, a single crystal solar cell, and a polycrystalline solar cell can be used, but it will be described using a polycrystalline solar cell that is more advantageous to the present invention. In FIG. 2, the cutting unit 15 is made by cutting the laser electrode between the finger electrode 11 and the finger electrode 11 of the solar cell, and each cutting unit 15 has one of the finger electrodes 11 according to the purpose. The spacing, two, three, etc. can be selected to make the cutout 15. If the cutting part 15 and the cutting part 15 are close to each other, the flexible solar cell is bent, i.e., the flexibility is good, and if the cutting part 15 and the cutting part 15 are wide, the flexible solar cell is bent. This results in an angle at each cut and bends into a polygonal form. Since the size of the crystalline solar cell is about 156 × 156 to about 200 × 200, if the space between the cutout 15 and the cutout 15 is wide, the flexible solar cell does not become flexible. Therefore, the closer the gap between the cutout portion 15 and the cutout portion 15, the better, and if necessary, the portion of the finger electrode 11 may be cut. Not only the bus bar electrode 13 connecting each finger electrode 11 but also the rear electrode is cut to form several solar cell pieces. And as seen in FIG. 3. On the back, each cut portion of the back electrode is connected by soldering the plating ribbon back electrode 20, and each busbar electrode 13 on the front is also electrically connected by soldering to the plating ribbon front electrode 23. The plated ribbon back electrode 20 and the plated ribbon front electrode 23 are each electrode connection wiring made by plating a solder on a copper thin plate, and are widely used in a solar cell module process. That is, if all the back electrodes on the cutout part 15 are connected to the plating ribbon back electrodes 20, and the busbar electrodes 13 are all connected to the plating ribbon front electrodes 23, the result is as shown in FIG. 4. While there is a performance of the bent features in the cut portion 15. That is, the plating ribbon back electrode 20 and the plating ribbon front electrode 23 are bent while bending at each cut portion 15. Since the plated ribbon back electrode 20 and the plated ribbon front electrode 23 are electrically connected to each other, the back electrode and the bus bar electrode 13 serve as the back electrode. FIG. 5 is a thin coating of transparent silicon 30 on both the back and the front surface in the configuration provided with the plating ribbon back electrode 20 and the plating ribbon front electrode 23 as described above, and there is a gap between the cut portions 15. All of them are filled with transparent silicon 30, the transparent silicon is wrapped on the back and front, and as a result, the solar cell is sealed in the transparent silicon (30). The material of the transparent silicon 30 may be sealed by various methods such as coating, dipping, molding, spraying, and molding using a transparent liquid silicone. Silicone rubber is a material that has good elasticity and has good chemical stability against sunlight. However, it is also a perfect non-conductor and a material with a lot of static electricity. Therefore, a small amount of the metal nanopowder may be blended in a range that does not significantly reduce the transparency to prevent static electricity, and silver nano, gold nano, carbon, copper, or the like may be used as the nano material of the metal. Instead of the material of the transparent silicon 30 described in the present invention, a transparent vinyl resin may be used. Vinyl resin is a good material that can seal the solar cell of the present invention because it is not stretchy but can be completely sealed and flexible. 6 and 7, the solar cell sealed with transparent silicon 30 is completed by attaching a double-sided adhesive 40 sheet on the back, the outermost layer of the double-sided adhesive 40 is provided with a backing paper, the adhesive surface is not exposed When using it, the inner adhesive surface is exposed when it is cut, and it can be attached and fixed where necessary. That is, the flexible solar cell 100 made in FIG. 7 has a cutting part 15, is electrically connected to the plating ribbon back electrode 20 and the plating ribbon front electrode 23, and sealed with transparent silicon 30. The double-sided adhesive agent 40 is provided in the back surface. 8 is a view showing an actual use example and will be described below. The cylinder 50 is a plan view of a circular pipe means. The back of the double-sided adhesive is scraped off the back of the flexible solar cell 100 of the present invention on the pipe pillar, and the adhesive surface is attached to the outer circumference of the pipe. Then, the plating ribbon back electrode 20 and the plating ribbon front electrode 23 are bent at each cutout portion 15, and the bending occurs and is fixed in the same shape according to the curve of the outer circumference of the cylinder 50. The flexible solar cell 100 of the present invention has a feature that the cylinder 50 can be adhesively fixed in the shape of the support around its outer circumference even if it is a polygonal support including a triangle, a square, a pentagon, and a hexagon. Therefore, all of the outer circumference of the column can be bonded to the flexible solar cell 100 to form a solar column-type solar cell, and also to fix and fix the solar cell in the form of tree branches, and consequently the solar cell in the form of a tree. I can make it. When the interval between the upper and lower cutting portions 15 and the solar cells of the cutting portions 15 of the flexible solar cell 100 of FIG. 9 is the same, the diameters of the pillars to be bonded and fixed are equal to those of the upper and lower diameters. It is preferable to fix the adhesive, and as shown in FIG. 10, the interval between the cut portions 15 of the flexible solar cell 110 is small, and the cut portions 15 below are wide, or each piece of the solar cell is placed above. Small, the bottom is connected to a larger piece, and as a result, the top of the flexible solar cell 110 consists of a small width, the bottom of the flexible solar cell 110 consisting of a larger width than the support is fixed fixed diameter It is preferable to fix and fix the posts that are different from the top and the bottom, that is, the top has a small diameter and the bottom has a large diameter. In FIG. 11, the flexible solar cell 120 has a cutout portion 15 both vertically and horizontally, and the upper and lower portions of the vertical solar cell 120 have the same spacing between the cutout portions 15 and the width of the slices of the solar cell, and the left and right sides of the horizontal side are the same. When the flexible solar cells 120 having the same spacing between the cut portions 15 and the width of the solar cells are the same, it is preferable to join the fixed column in the form of a sphere or a more complicated three-dimensional column. That is, the flexible solar cell 120 creates a curve that can be fixed to the bonnet of the car having a curve, the roof of the car, the side of the car and the like. Therefore, the flexible solar cell 100, the flexible solar cell 110, and the flexible solar cell 120 described in the present invention are wooden pillars, tree branches, building exterior walls, pier railings, pier columns, automobile bodies, and motorcycle bodies. It is a silicon crystalline flexible solar cell that can be attached and fixed to the body of a bicycle.
