Flexible thin film solar cells have advantages over conventional solar cells:
1 Structural advantages:
Cells Conventional solar systems generally have two. In the middle of the glass layers is a structure made of EVA material and battery sheets. These components are heavier and require supports during installation, making them difficult to move. Flexible thin-film solar cells do not require glass backsheets or covers and are 80% lighter than double-glass solar cell modules. Flexible cells using PVC backsheets and ETFE film covers can even be folded at will, making them easy to transport.
2. Advantages:
Can be used in solar backpacks, solar convertibles, solar flashlights, solar cars, sailboatssolar and even solar planes. The scope of use is relatively wide. The disadvantage is that the photoelectric conversion efficiency is lower than that of conventional crystalline silicon components. There is also a semi-flexible solar panel with a high conversion rate that can only be bent about 30 degrees. Guangrui Industrial Co., Ltd. is relatively mature in the production of solar panels for this type of product.
3. Advantages of assembly:
Dye-sensitized solar cells and organic perovskite solar cells combined with nanotechnology have obvious advantages in the assembly of materials and devices and are currently more common in the world. flexible solar cells.
To obtain high-performance dye-sensitized flexible solar cells and promote their industrialization, advances must be sought in thes following aspects. On the one hand, there is a need to further improve the photoelectric conversion efficiency and stability of dye-sensitized flexible solar cells. Another aspect is to further reduce the cost of batteries and enable the preparation of large-scale roll-to-roll printing.
The impact of flexible substrates and rigid substrates on organic solar cells
Flexible solar cells are a type of thin-film solar cells with with advanced technology and excellent performance, low cost and wide range of uses. It can be applied to solar backpacks, solar convertibles, solar flashlights, solar cars, solar sailboats and even solar airplanes. An important application area of flexible solar energy is BIPV (Building Integrated Photovoltaic), which can be integrated into windows or roofs, exterior walls andexterior or interior.
1. The impact of flexible substrates on organic solar cells: Flexible organic solar cells have the advantages of low cost, light weight and flexibility, and can be used as power systems for portable electronic devices . systems. The efficiency of flexible devices remains 15-17%.
2. The impact of rigid substrates on organic solar cells: The efficiency of rigid devices is maintained at 19%, and heat treatment, solvent treatment and post-processing easily implemented on rigid substrates improve the performance of devices. . Organic solar cells are solar cells whose core is made of organic materials. Mainly using organic matter with photosensitive properties as semiconductor materials, the photovoltaic effect generates voltage to form current,thus achieving the effect of solar power generation.
