1. What are the advantages of flexible solar panels over ordinary crystalline silicon?
Flexible thin film solar cells are distinguished from conventional solar cells:
Conventional solar cells are generally composed of two layers of glass with EVA material and cells in the middle. Such components are heavy and require brackets during installation, which is not easy to move.
Flexible thin-film solar cells do not need glass backsheets and cover sheets, and are 80% lighter than double-glazed solar cell modules. Flexible cells with pvc backsheets and ETFE film cover sheets can even be bent arbitrarily, making them easy to carry. It can be applied to solar backpacks, solar convertibles, solar flashlights, solar cars, solar sailboats and even solar planes. It is widely used. The disadvantage is that the photoelectric conversion efficiency is lower than that of conventional crystalline silicon modules.
There is also a semi-flexible solar panel, which has a high conversion rate and can only be bent at about 30 degrees. The solar panel of this type of product is relatively mature.
2, What is the maximum conversion rate of flexible solar panels
There are currently five main categories of flexible solar panels, and the specific conversion rates are as follows:
1. Organic solar photovoltaic cells:
1. Advantages: flexibility;
2. Disadvantages: sensitive to water vapor, low conversion efficiency;
3. Conversion efficiency: about 8%;
2. Amorphous silicon solar photovoltaic cells:
1. Advantages: flexibility, low cost;
2. Disadvantages: low conversion efficiency;
3. Conversion efficiency: 10%-12%;
3. Copper indium gallium selenide solar photovoltaic cells:
1. Advantages: flexibility, light weight, low cost, low light power generation, no hot spots
2. Disadvantages: the production process is complicated;
3. Conversion efficiency: 14%-18%
Fourth, cadmium telluride solar photovoltaic cells:
1. Advantages: large-scale production, low cost;
2. Disadvantages: rigid, toxic;
3. Conversion efficiency: 16%-18%;
5. Gallium arsenide solar photovoltaic cells:
1. Advantages: flexibility, light weight, high power generation efficiency, low light power generation, no hot spots
2. Disadvantages: the production process is complicated;
3. Conversion efficiency: 28%-31%;
flexible
1. In terms of physical flexibility, the English name is Flexible, which can also be interpreted as flexibility, which is a kind of object characteristic relative to rigidity. Flexibility refers to a physical property that an object deforms after being subjected to force, and the object itself cannot return to its original shape after the force is lost. After a rigid object is subjected to force, its shape can be regarded as unchanged from a macroscopic point of view. Elasticity refers to a physical property that an object deforms after being subjected to a force, and the object itself can return to its original shape after the force is lost. It focuses on the deformation results of the object, while flexibility focuses on the properties of the object itself. 2. Social aspects are often used in terms of flexible management and flexible production.
efficiency
Efficiency refers to the ratio of useful power to driving power, and it also has a variety of meanings. Efficiency is also divided into many types, such as mechanical efficiency (mechanical efficiency), thermal efficiency (thermal efficiency) and so on. Efficiency is not directly related to the speed of work. Efficiency refers to the evaluation of the most efficient use of resources to meet set wishes and needs given inputs and technologies.
