What are the classifications of photovoltaic cells and what are the influencing factors?
1. Various classifications of photovoltaic cells
1. Monocrystalline silicon photovoltaic cells
Monocrystalline silicon photovoltaic cells are a type of photovoltaic cell that was developed earlier, has the highest conversion rate, and has a large output. The conversion efficiency of monocrystalline silicon photovoltaic cells has reached an average of 16.5% in my country, and the highest conversion efficiency recorded in the laboratory exceeds 24.7%. This kind of photovoltaic cell generally uses high-purity monocrystalline silicon rods as raw materials, with a purity requirement of 99.9999%.
2. Polycrystalline silicon photovoltaic cells
Polycrystalline silicon photovoltaic cells are photovoltaic cells based on polycrystalline silicon materials. Since polycrystalline silicon materials are mostly cast instead of the drawing process of single crystal silicon, the production time is shortened and the manufacturing cost is greatly reduced. In addition, monocrystalline silicon rods are cylindrical, and photovoltaic cells made from them are also wafers, so the plane utilization rate after forming photovoltaic modules is low. Compared with monocrystalline silicon photovoltaic cells, polycrystalline silicon photovoltaic cells appear to have certain competitive advantages.
3. Amorphous silicon photovoltaic cells
Amorphous silicon photovoltaic cell is a new type of thin film battery made of amorphous silicon as raw material. Amorphous silicon is a semiconductor with an amorphous crystal structure. Photovoltaic cells made with it are only 1 micron thick, equivalent to 1/300 of monocrystalline silicon photovoltaic cells. Compared with monocrystalline silicon and polycrystalline silicon, its manufacturing process is greatly simplified, silicon material consumption is less, and unit power consumption is also reduced a lot.
4. Copper indium selenide photovoltaic cells
Copper-indium-selenide photovoltaic cells are semiconductor films made of copper, indium and selenium ternary compound semiconductors deposited on glass or other cheap substrates. Due to the good light absorption performance of copper indium selenide cells, the film thickness is only about 1/100 of that of monocrystalline silicon photovoltaic cells.
2. Factors affecting photovoltaic cell output
1. Effect of temperature on the output characteristics of photovoltaic cells and components
As we all know, when the temperature of photovoltaic cells and components is high, the working efficiency decreases. As the temperature of the photovoltaic cell increases, the open circuit voltage decreases. In the range of 20-100 degrees Celsius, the voltage of the photovoltaic cell decreases by about 2mV for every 1 degree Celsius increase. The photocurrent increases slightly with the increase of temperature, about every 1 degree Celsius. The photocurrent of the battery increases by one thousandth when the temperature rises by 1 degree Celsius. In general, for every 1 degree Celsius increase in temperature, power is reduced by 0.35%. This is the basic concept of temperature coefficient. Different photovoltaic cells have different temperature coefficients, so the temperature coefficient is one of the criteria for judging the performance of photovoltaic cells.
2. Effect of light intensity on the output characteristics of photovoltaic cell modules
Light intensity is proportional to the photocurrent of photovoltaic cells and components. Within the range of light intensity from 100 to 1000 watts per square meter, the photocurrent always increases linearly with the increase of light intensity; while light intensity has little effect on voltage, and changes in temperature Under fixed conditions, when the light intensity changes within the range of 400-1000 watts per square meter, the open circuit voltage of photovoltaic cells and modules remains basically unchanged. Therefore, the power of photovoltaic cells is basically proportional to the light intensity.
