Technical indicators of solar cell sorting machine

1. Open Circuit Voltage (Voc): The battery voltage when there is no load under the light. 2. Short circuit current (Isc): The output current when the battery is short circuited under the light. light.

4. Voltage (Vopt)/current (Iopt) at maximum power.

5. Fill factor: Pmax/Voc * Isc, reflecting the variation in battery power output with load

6 Efficiency: The operating efficiency of the cell under light

7. Equivalent series resistance: The equivalent series resistance inside the solar cell will affect its direct volt-ampere characteristics and short-circuit current. In addition, increasing the series resistance will reduce the fill factor and photoelectric conversion efficiency of the solar cell. solar cellp>

What are the preparations before the arrival and installation of the solar cell sorting machine?

The correct way to handle the battery is that when sorting and inspecting the battery, the operator should pick up the middle part of the battery and handle it carefully.

Solar cells are generally divided into monocrystalline silicon, polycrystalline silicon and amorphous silicon. Monocrystalline silicon solar cells are currently the most rapidly developed type of solar cell. Its structure and production process have been finalized, and its products. has been widely used in space and on the ground.

This type of solar cell uses high purity monocrystalline silicon rods as raw material. To reduce production costs, solar cells for ground applications use solar-grade monocrystalline silicon rods, and performance indicatorsormance of materials have been relaxed. Some may also use scraps and waste monocrystalline silicon materials from semiconductor device processing and then redesign them into monocrystalline silicon rods specifically for solar cells.

In solar cell products, silicon semiconductor materials are the main ones, represented by monocrystalline silicon and polycrystalline silicon. Due to its wide range of raw materials, high conversion efficiency and reliability, it is widely accepted by the market.

Amorphous silicon is also widely used in civilian products (such as electronic watches, calculators, etc.), but its stability and conversion efficiency are lower than that of crystalline semiconductor materials .

Compound solar cells are not widely adopted in the market at this stage due toon the rarity of their materials and the environmental risks of certain materials. The main product of solar cells is semiconductor silicon, which is indispensable. For the modern electronics industry, the raw material silicon, in its oxidized state, constitutes the second largest material reserve in the world.

Unpacking and preparation

1. Unpacking

· Prepare crowbars and hammers.

· Please use caution when moving equipment, a forklift is recommended.

2． Preparation before installation

· Ensure that the 220V power supply is in place (the power socket must be earthed and the test equipment must be earthed independently

).

· The pressure of the external air pressure source is set to 0.8Mpa.

· The external 8mm air pipe is several meters long and the air valve switchis individual.

· Ensure that the equipment operates at a constant temperature of 25°C.

· Several standard battery plugs.

· Tools (hexagonal socket, multimeter, screwdriver, etc.).

I have already purchased it once from Wuhan Sanggong Optoelectronic Factory. Their service is pretty good and they have detailed installation instructions. You can search online to find out more. Hope this helps.
