Specifications

AL8866 is a series of aluminum pastes developed for use as the back electrode on single or polycrystalline silicon solar cells.

Technical Data Sheet

Product description

AL8866 is a series of aluminum pastes developed for use as the back electrode on single or polycrystalline silicon solar cells. This low bow aluminum paste is specially designed to form p+ doped layer when fired on a p-doped silicon (<200 microns) photovoltaic devices. This paste has been optimized to eliminate Al bead formation during the firing process.

Q:What is the role of voltage regulators in solar cell systems?
The role of voltage regulators in solar cell systems is to regulate and control the voltage output from the solar panels to ensure it remains within a specific range that is suitable for the connected devices or batteries. This helps prevent overcharging, which can damage the devices or batteries, and ensures optimal performance and efficiency of the solar cell system.
Q:Can solar cells be used for powering airports?
Yes, solar cells can be used for powering airports. Solar panels can generate electricity from sunlight, which can be used to power various airport operations such as lighting, air conditioning, and charging stations for electric vehicles. Additionally, airports often have large open spaces, such as runways and parking lots, which can be utilized for installing solar panels and harnessing solar energy. This can not only reduce the airport's carbon footprint but also provide a more sustainable and cost-effective energy solution.
Q:What is the maximum efficiency achievable by a solar cell?
The maximum efficiency achievable by a solar cell is determined by the Shockley-Queisser limit, which states that the theoretical maximum efficiency is around 33.7%. However, in practice, most commercially available solar cells have efficiencies ranging between 15% to 22%.
Q:What is the current situation and the recent progress space solar cells in China?
Because the power supply system is one of the important subsystems of the satellites, they need to be configured with a suitable, reliable power subsystem. The proportion of the power subsystem in the whole satellite system is the highest, so the research on the power supply system is very important.
Q:How do solar cells affect the electricity grid?
Solar cells affect the electricity grid by injecting clean and renewable energy into the system. When solar cells generate excess electricity, it can be fed back into the grid, reducing the demand for electricity from traditional power plants. This helps diversify the energy sources and reduce carbon emissions. However, the intermittent nature of solar power can pose challenges to grid stability and require additional infrastructure investments for efficient integration.
Q:How does the photovoltaic cells work?
Photovoltaic solar cells fulfill two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity.
Q:Can solar cells be used for powering sports stadiums?
Yes, solar cells can be used for powering sports stadiums. They have the ability to generate electricity from sunlight and can be installed on the roof or surrounding areas of the stadium. This renewable energy source can help reduce the carbon footprint of the stadium and contribute to a more sustainable and environmentally friendly power supply.
Q:What kind of products can be considered as the solar cell products?
Anything you can think about that is powered by solar cells are considered to be the solar cell products.
Q:How do solar cells perform in areas with high levels of electromagnetic interference?
Solar cells can be affected by high levels of electromagnetic interference (EMI), which can lead to reduced performance. EMI, such as radio frequency interference or electromagnetic radiation from nearby electronic devices, can disrupt the proper functioning of solar cells by interfering with their ability to convert sunlight into electricity. Therefore, in areas with high EMI levels, solar cells may experience decreased efficiency and output. Implementing shielding techniques and using quality components can help mitigate the impact of EMI on solar cell performance.
Q:What is the lifespan of solar cells?
The lifespan of solar cells typically varies between 25 to 30 years, although some high-quality panels can last up to 40 years with proper maintenance and care.
