By delving into the specifics of AVIC Photoelectric’s products, we can appreciate the complexity and sophistication of modern photoelectric solutions.
Photovoltaic (PV) cells are the heart of any solar energy system. They convert sunlight directly into electricity through the photovoltaic effect. When light photons strike the surface of a PV cell, they excite electrons, creating an electric current.
AVIC Photoelectric utilizes several types of photovoltaic cells, each with its unique characteristics:
Monocrystalline: Made from a single crystal structure, these cells are known for their high efficiency and longevity. They typically have a higher power output per square meter compared to other types.
Polycrystalline: These cells are made from multiple crystal structures, making them less expensive to produce. While they are slightly less efficient than monocrystalline cells, they offer a good balance between cost and performance.
Thin-film: This type of cell is made by depositing a thin layer of photovoltaic material onto a substrate. Thin-film cells are lightweight and flexible, making them suitable for a variety of applications, although they generally have lower efficiency.
The efficiency of photovoltaic cells is a critical factor in determining the overall performance of solar panels. AVIC Photoelectric focuses on optimizing the efficiency of its cells, with many of its products achieving efficiencies above 20%. Performance metrics such as temperature coefficient, degradation rate, and power tolerance are also essential in evaluating the long-term viability of these cells.
Optical components play a vital role in enhancing the performance of photoelectric systems. Lenses are used to concentrate and direct sunlight onto photovoltaic cells, increasing their efficiency.
Types of Lenses Used: AVIC Photoelectric employs various lens types, including Fresnel lenses and aspheric lenses, to optimize light capture.
Role in Light Concentration and Direction: By focusing sunlight onto a smaller area, lenses can significantly boost the energy output of solar panels, making them more effective in diverse lighting conditions.
Mirrors are another critical optical component in photoelectric systems. They reflect and direct sunlight towards photovoltaic cells, enhancing their exposure to light.
Types of Mirrors: AVIC Photoelectric uses parabolic and flat mirrors, each serving specific applications in solar energy systems.
