The method of making your own solar panels is as follows:
1. Design the cell size according to the glass size Generally, each side of the cell. is 5 mm from the edge of the glass. The battery is the main one. With the grid line as the center, use a cutting machine to cut the solar cells into several pieces whose number is the same as the number of glass; /p>
2. Use a ruler and a wallpaper knife to cut the EVA and backing. Cut the board into several small pieces slightly larger than the glass. The amount of EVA should be twice as much. quantity of glass;
3. Use scissors to cut the soldering tape to a length slightly longer than the length of the glass. The number of small sections should be double the number of. glass ;
4. After completing the above hardware preparations, start usingUse a soldering iron to solder the main grids on both sides of the battery part. Solder the tape on the line, and the force should not be too strong to avoid crushing the battery piece;
5. In order of Glass, EVA, Battery Piece, EVA, and Backplane, start with Place. materials in order from bottom to top. Once all materials are laid, place them in the laminator to avoid misalignment, they can be secured with tape; > 6. Place the layers Remove the small pressed solar panels. Once the temperature has dropped to room temperature, use a wallpaper knife to remove excess material from around the glass. Finally, use a soldering iron to connect the small independent solar panels in series. and they are ready to use.
How to make a small solar generator yourself
The first step: first put the powdertitanium dioxide in a mortar and grind it with a binder
Then use The glass rod slowly covers the conductive glass to produce a titanium dioxide film.
Place the film of titanium dioxide under an alcohol lamp to sinter and solidify for 10-15 minutes, then cool
Secondly. Step: Use natural dyes to color the titanium dioxide. As shown in the picture, squeeze fresh or frozen black plums, mountain plums, pomegranate seeds or black tea with a large spoon to extract the juice, then put the titanium dioxide film into it. coloring. It will take about 5 minutes, until the film layer turns dark purple. If both sides of the film layer are unevenly colored, you can put it on and soak it for 5 minutes, then rinse it with ethanol and dry it. gently.
Step 3: Make the positive and negative electrodes ofbattery. It is composed of a layer of SnO2 conductive film, and a layer of graphite is evenly coated on the conductive surface with a 6B pencil.
Step 4: Add electrolyte. Use a solution containing iodine ions as the solar cell electrolyte. As the picture shows, just add one to two drops of electrolyte on the surface of the titanium dioxide film.
Step 5: Assemble the battery. Place the colored titanium dioxide film on the table, drop one or two drops of electrolyte containing iodine and iodide ions on the film, and then place the conductive surface of the negative electrode Press on the titanium dioxide membrane. Offset the two pieces of glass slightly so that the exposed part can be used as the electrode for the test. Use two pliers to tighten the battery and your solar battery is ready.
Step 6: Test the battery outdoorsUnder sunlight, you canget a solar cell with an open circuit voltage of 0.4 V and a short circuit current of 1 mA/cm2
The cost is a bit boring and the technology is also difficult. It is recommended to purchase solar panels + batteries + inverters to do so.
You can only generate photothermal energy by yourself. Paint an aluminum plate black, press the thermoelectric power generating part below and below the thermoelectric power. The generating part is an aluminum plate, and dip the aluminum plate underneath into water. But the electricity produced is pitiful.
2. Use hot water from solar water heater + thermoelectric film: make a heat exchanger, use hot water to heat the upper plate, and use cold water to cool the lower plate if there is a temperature. difference on both sides of the thermoelectric film, the eleElectricity will be generated.
3. Use heat pipes + thermometers
4. Heat pipes + working fluid Freon + thermal engine + generator (the configuration of a solar power plant cannot be carried out by individuals)
