Simply stick it to the barrel with glue. . . I see the front of your bucket is still a little flat. It should be able to be pasted~ But in this case, the lighting of the solar panel will not be very good, because it will be vertical after being pasted? ~? Look at it like in the sketch. How about sticking? You can use large pieces of foam or soft materials that are easy to modify. Use tools to create a concave surface similar to the curved surface of the barrel and glue it on top. surface of the barrel. It should be very strong~
As for the use of flat steel as supports mentioned below? It seems that even if it is assembled, it will still be quite bulky~

Background
The Traditional fossil fuels such as oil, natural gas and coal are non-renewable resources and will release a large amount of them. of dcarbon dioxide when burned, causing the greenhouse effect and destroying the ecological balance. Therefore, based on new technologies and materials, humans have begun to use new clean, environmentally friendly, environmentally friendly and renewable energy sources, such as: solar energy, biomass energy, wind energy, geothermal energy, wave energy, ocean currents. energy, tidal energy, etc.
Solar energy is one of the most representative new energy sources and has extremely high development and utilization value. Its advantages are: clean, environmentally friendly, renewable, easy to obtain, low cost, etc. Currently, the most common way to use solar energy is through solar power generation, in which solar cells play a key role. In articlesPreviously, the author presented a number of innovative research developments related to solar cells.

However, the use of solar cells to produce electricity has always faced a constraint: rainy weather conditions can seriously affect the production of electricity. electricity. In areas where it rains frequently, solar cells may not be a good choice because overcast clouds block sunlight, thereby affecting the amount of electricity generated by the solar cells.
Innovation
Recently, the research group of Professor Sun Baoquan and Professor Sun Xuhui from the Institute of Nanofunctions and Soft Matter at Soochow University in China has published an article in “ACS Nano”. , combining solar cells with a triboelectric nanogenerator (TENG), was combined to develop a hybrid solar cell capable of producing electricityelectricity from sunlight and raindrops.
Technology
Friends who have read the author's articles will know about triboelectric nanogenerators. Previous articles such as: “New triboelectric nanogenerators: can use human movements” Realize wireless power supply! », “New triboelectric nanogenerator: inspired by traditional Chinese cutting! ", "Is it possible for wearable devices to be powered by the movements of the human body? », “A golden label to stick on the skin: Use the movements of the human body to produce electricity! 》 presented the research results on triboelectric nanogenerators.
In simple terms, triboelectric nanogenerators generate electricity by harvesting the mechanical energy around us, for example using the energy from human body movements, such as bending fingers or running.

What is the energy production principle of the triboelectric nanogenerator?
Due to the triboelectric effect, in the internal circuit of the triboelectric nanogenerator, a charge transfer occurs between two thin layers of materials of different triboelectric polarities, forming a potential difference between them in the circuit external of the nanogenerator; triboelectric nanogenerator, the electrons are driven by the potential difference and circulate “between the two electrodes” on the back of the layer of triboelectric material or “between the electrode and the earth” to balance this potential difference.
Many previous studies on triboelectric nanogenerators have attempted to use the energy of human body movement to produce electricity. However, researchers at Suzhou University used the energy of raindrops to generate electricity. They aret integrated triboelectric nanogenerators into solar cells, allowing solar cells to efficiently produce electricity even on rainy days. Similar studies have already been done that added pseudocapacitors or triboelectric nanogenerators (TENGs) to solar cells, but these devices tend to be very large and difficult to manufacture, and the Soochow University team aimed to develop a better hybrid energy recovery system.
So what's so special about this hybrid solar cell?
The researchers used two polymer materials: PDMS and PEDOT:PSS. PDMS refers to polydimethylsiloxane, and PEDOT:PSS is an aqueous solution of high molecular weight polymer with very high conductivity.
The triboelectric nanogenerator is located on top of the solar cell and combines PDMS as a triboelectric material with a P layerEDOT:PSS as electrode. The PEDOT:PSS thin film is located between the solar cell and the triboelectric nanogenerator and becomes the common electrode of the solar cell and the triboelectric nanogenerator. In the case of solar cells, the addition of PEDOT:PSS can reduce light reflection, thereby improving its performance. When the raindrops fall, the triboelectric nanogenerator on the upper layer is activated, and the PEDOT/PSS material film layer transmits the electrical energy generated by the triboelectric nanogenerator to the solar cell. Additionally, because the polymer is transparent, solar cells can still harvest energy from the sun on sunny days.

What precautions are necessary when maintaining solar panels?
Scout?Campers has designed better camper shells for vans, including the latest product It is "Yoho", which allows mid-size pickup truck owners to go out and enjoy outdoor activities all year round, and has complete camping equipment and lightweight features.
Lightness is not just talk. Scout Campers said Yoho is the lightest non-soft camping shell in the industry. The base model weighs only 414 kilograms, which won't exceed the maximum load of the Ford Ranger or Toyota? capacity of a pickup truck like the Tacoma, but the Yoho can have such light weight is mainly due to the structure, which useswood as the structure of the aluminum exoskeleton and makes it a composite material.
Although Yoho is a streamlined camping shell, it still has a surprising number of amenities. The interior space is 191 cm high and most people can stand upright in it. The higher version will be equipped with a roof. standard solar panels and Yeti mobile power pack? 1000? Power? The water system part has a 19 liter mobile water tank with an integrated filtration system. converted into a double bed, more In the sleeping area at the top, Yoho can comfortably accommodate up to four people sleeping outside for a night.

What precautions are necessary for the maintenance of solar panels?
A solar panel is a device that converts solar energy into electrical energy. Its performance and lifespan are linked to maintenance. So, what should we pay attention to in maintaining solar panels?
First of all, clean the dirt and dust on the surface of the solar panel regularly. Due to different installation locations, there may be various dirt and dust on the surface of the solar panel, which will affect the working efficiency of the solar panel. Regular cleaning is therefore necessary. When cleaning, use a chisoft sponge or sponge and avoid using stiff bristle brushes, wire brushes, scrapers and other objects that may scratch the surface. At the same time, be careful not to use chemicals when cleaning.
Second, pay attention to the installation location and storage method of solar panels. Solar panels should be installed where they are not covered by objects. Place in a sheltered, sunny location and avoid large areas of shadow. At the same time, avoid long-term exposure of solar panels to sunlight during storage, and choose a dry, ventilated and shaded place for storage. For solar panels that are not used for a long time, they should be placed in a dry and ventilated place to prevent moisture from negatively affecting them.
Finally, regularly check whether the solar panel circuit connection is normal. That the cWhether the circuit connection is normal or not is the key to whether the solar panel can produce electricity normally. Therefore, we should regularly check whether the circuit connections of solar panels are loose or damaged, and pay attention to whether there is corrosion or cracks on the surface of the panels.
In short, the maintenance of solar panels is crucial, which directly affects the efficiency and lifespan of solar panels. Through the above maintenance measures, we can keep solar panels in good working condition and bring more convenience and comfort to our lives.
