With the reduction of cost and weight and the improvement of power generation efficiency, solar power generation is penetrating into various fields, such as agriculture, construction, automobile and even aviation. Hanergy, the world's leading thin-film solar power company, produces a variety of products such as Han tiles, Han walls, Han roads, Han paper, Han bags and Han umbrellas. Users can also install Han tiles on their roofs. thin-film solar power generation pigsties, film vegetable greenhouses, space satellite power generation batteries, shared bicycle power generation batteries

Silicon Silicon (Si) is a tetrahedrally coordinated atom, usually tetrahedrally bonded to four adjacent silicon atoms.
Amorphous silicon is also called amorphous silicon. Its English name is Amorphous Silicon (a-Si). . The product does not crystallize during the process. The atoms in it form a continuous random network and not all atoms are coordinated on all sides. Due to the disorder of the material, some silicon atoms have dangling bonds, that is, there are no electrons attached to the surrounding silicon atoms. These electrons can generate current under the action of an electric field.
In crystalline siliconCrystalline silicon (c-Si), the tetrahedral structure persists over a wide range, forming an ordered lattice. Crystalline silicon is divided into monocrystalline silicon (monocrystalline) and polycrystalline silicon (polycrystalline silicon is a single crystal of silicon, a crystal with a basically lattice structurecomplete). Polycrystalline silicon is made up of small crystal grains, also called dice. The difference between polycrystalline silicon and monocrystalline silicon is mainly reflected in physical properties.
Amorphous silicon solar panels have low resistance to light and can generate a certain amount of current inside. Most of them are commonly used in some calculators. Amorphous silicon solar cells likely includegallium arsenide (GaAs), indium phosphide (InP), cadmium telluride (CdTe), copper indium gallium selenide ( CIGS)These, then amorphous silicon solar cells. It's probably the cards. The most common on the market are cadmium telluride (CdTe) and copper-indium-gallium selenide (CIGS). Due to the collapse of Hanergy, copper-indium-gallium selenide (CIGS)is now practically exhausted. The flexibility of amorphous silicon solar panels is much better than that of crystalline silicon solar panels, and the bending degree can reach 90 to 180 degrees. Today, many people take advantage of this feature and want to fold them onto telephone poles to cover a large area. areas, and simply bend itThe forest trunk is average, but its conversion efficiency is only about 7-10%, and its price is higher than that of crystalline silicon solar panels, so it does not 'is not widely used.
Crystalline silicon solar panels are only suitable for outdoor use in sunny locations. The conversion efficiency of monocrystalline silicon solar panels is 20-24%, and the conversion efficiency of polycrystalline silicon solar panels is about 14-19%. The price of single crystal siliconin is >polycrystalline silicon. Common applications in life include solar street lights, solar folding bags, solar traffic lights, solar GPS, RVs, etc.
