If it is an open solar system, the gas will be naturally discharged after high temperature production. If it is a closed solar system, it is usually vented through a pressure relief valve, so there is no need to manually vent it. Of course, exhaust is very important, otherwise air blockage will occur. Image system efficiency or normal operation.
The first step: first put the titanium dioxide powder into a mortar and grind it with a binder
Then use a glass rod to slowly apply a film on conductive glass to produce titanium. Titanium Dioxide Membrane
Put the titanium dioxide film under an alcohol lamp to sinter and solidify for 10-15 minutes, then cool it
Step 2: Use natural dyes to color titanium dioxide As picture shows. Frozen black plums, mountain plums, pomegranate seeds or they black, use a big spoon to extract the juice from it, then put the titanium dioxide film to color it, it will take about 5 minutes until the film layer is formed. turns dark purple if the film layer is colored on both sides. If it is uneven, you can put it in and soak it for 5 minutes, then rinse it with ethanol and gently dry it.
Step 3: Make the positive and negative electrodes of the battery. 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 a ou 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: Battery Test Under outdoor sunlight, a solar cell with an open circuit voltage of 0.4V and a short circuit current of 1mA/cm2 can be obtained .
