Personally, I think the only possible way to convert light energy into electrical energy is to use silicon photovoltaic cells,
then use batteries to store the electricity,
Because light energy is very unstable,
Using some resistor-capacitor components and inductors to construct a circuit can increase the conversion efficiency. . .
What I still don't understand is where should the communication floor be arranged?
How to make simple photovoltaic solar panels yourself?
Solar panel, one or two mobile phone batteries connected in series, a diode, a PNP transistor, one or more LED lamp beads (it is better to add a limiting resistor current, multiple LEDs are required for one battery) When two batteries are connected in parallel or series, the LEDs must also be connectedare in series). The base of the triode is polarized with a solar panel, the collector is connected to the LED, and the base is connected to the positive electrode of the battery. As shown in the image below, the solar panel does not generate electricity at night, but there is a leakage current, which simply provides a bias current to the transistor, making it conductive. The mobile phone lithium battery has a protective plate and will automatically shut down when fully charged.
How to make your own small home solar generator
You can buy derated battery sheets online, get tinned copper strips if possible and use a soldering iron Connect the battery cells in series (note that the back of the battery is the positive electrode, the front is the negative, and the positive and negative electrode ribbons cannot touch each other), so that the threadthe back of the battery is the DC positive electrode, and the wire of the front of the battery is the DC negative, so it is already a power generation equipment. If you want this power generation equipment to last longer, you need to insulate the cells from air and have a DC positive electrode. certain mechanical resistance. Currently, conventional components must be laminated with EVA, backplane and glass. The family should not, at most, be sealed with resin, which of course may not be easy for families to implement. I tell you that the current operating voltage of 8" polycrystalline cells is 0.5V per day. You should consider the voltage of the charging device to decide how many batteries to use.
Solar energy
< p>Solar energy refers to the energy of thermal radiation from the sun (see the three modes of propagation of energythermal energy: radiation). The main manifestation is often called solar rays. In modern times, it is generally used to generate electricity or. supply energy to water heaters.Since the birth of life on earth, it has mainly depended on thermal radiation energy provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects. As a method of making food, such as making salt and drying salted fish, solar energy has become an important part of human energy consumption, and the use of solar energy includes conversion photothermal and photoelectric conversion. emerging renewable energy source. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc.
Small homemade solar water heater h3>
The lThe cost is a bit annoying, and the technology is also difficult. It is recommended to purchase solar panels + batteries + inverters.
You can only produce photothermal energy by painting an aluminum plate black. below. Under the sheet of the thermoelectric generator 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, electricity 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 bys individuals)
Take a wooden box similar to a drawer, put a 4 to 5 cm thick foam board (or an old quilt) on the bottom and around it, and cover the box with wood from a piece of glass (or plastic sheeting). Place 1-2 water tanks inside, with a diameter of 15-20cm and a height of 60-100cm. They are made of galvanized sheets and filled with water. The exterior of the melter is painted black, with a water inlet inside. at the bottom and an exit at the top. The water inlet is connected to the house's hot water tap. There is an overflow opening on the top. When the water is full and overflowing, close the water inlet valve. Such a simple solar water heater is made. Water temperatures can reach 60 degrees in summer and 45 degrees in winter.
