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:How do solar cells perform in cloudy weather?: Solar cells do not perform as efficiently in cloudy weather compared to sunny conditions, as they rely on direct sunlight to generate electricity. However, they can still generate some electricity, albeit at a reduced rate, as they can absorb diffuse sunlight and convert it into energy.

Q:What is the role of voltage regulators in solar cell systems?: The role of voltage regulators in solar cell systems is to ensure a stable and regulated output voltage from the solar panels. They act as a control mechanism to prevent overcharging of batteries or damage to electronic devices by regulating the incoming voltage from the solar cells. Voltage regulators also help optimize the efficiency of the solar cell system by matching the voltage levels of the solar panels with the load requirements, thereby maximizing the energy conversion and utilization.

Q:What is the role of combiners in solar cell systems?: The role of combiners in solar cell systems is to combine the electrical outputs from multiple solar panels into a single output, increasing the overall power output of the system.

Q:What is the role of solar cells in powering water pumping systems?: Solar cells play a crucial role in powering water pumping systems by converting sunlight into electricity, which is then used to run the pumps. This renewable energy source eliminates the need for traditional fuel sources and provides a sustainable and cost-effective solution, especially in remote or off-grid areas where access to electricity is limited.

Q:Can solar cells be used on vehicles other than cars?: Yes, solar cells can be used on vehicles other than cars. They can be installed on motorcycles, buses, trucks, boats, and even airplanes to generate electricity and reduce reliance on fossil fuels.

Q:What are the maintenance requirements for solar cells?: The maintenance requirements for solar cells are minimal. They generally require regular cleaning to remove dust or debris that may accumulate on the surface, and occasional inspection to ensure proper functioning and detect any signs of damage or wear. Additionally, it is recommended to check the connections and wiring periodically to ensure they are secure. Overall, solar cells are known for their durability and low maintenance needs.

Q:Can solar cells be used in underwater vehicles or submarines?: Yes, solar cells can be used in underwater vehicles or submarines. However, due to the limited availability of sunlight underwater, the efficiency of solar cells in generating power is significantly reduced. Therefore, solar cells are often used as a supplementary power source in combination with other power systems such as batteries or fuel cells in underwater vehicles or submarines.

Q:Can solar cells be used to power off-grid cabins or homes?: Yes, solar cells can definitely be used to power off-grid cabins or homes. Solar panels can convert sunlight into electricity, which can then be stored in batteries for use during the night or when the sun is not shining. This renewable energy source provides a sustainable and reliable power solution for off-grid living, reducing dependence on traditional energy sources.

Q:Why should the solar cells be laserized?: While the P2, P3 level with green nano-laser is the most ideal. In the actual experiment process using green picosecond laser technology the best, but taking into account the cost of equipment into the point of view, green nanosecond most ideal

Q:What is the role of solar cells in powering streetlights?: The role of solar cells in powering streetlights is to capture sunlight and convert it into electricity, which is then stored in batteries. This stored energy is used to power the streetlights during the night, reducing the dependence on the electrical grid and minimizing energy costs and environmental impact.
