6 FAQs about [Photovoltaic effect data of photocell]
How does temperature affect photovoltaic cells?
For the photovoltaic cells with constant resistance load, the output voltage, current, and output power of the photovoltaic cells decrease obviously with the increase of the temperature of the photovoltaic cells, and the photoelectric conversion rate of the photovoltaic cells shows a linear downward trend.
What is the photoelectric conversion rate of a photovoltaic cell?
The photoelectric conversion rate of the photovoltaic cell is the ratio of the output power of the photovoltaic cell to the total solar radiation power radiated on the surface of the photovoltaic cell:
What is photovoltaic effect?
The photovoltaic effect is the generation of voltage and electric current in a material upon exposure to light. It is a physical phenomenon. The photovoltaic effect is closely related to the photoelectric effect. For both phenomena, light is absorbed, causing excitation of an electron or other charge carrier to a higher-energy state.
How does sunlight affect a PV cell?
When a PV cell is subject to the sunlight, the absorbed amount of light generates electric energy while remaining sunlight can be reflected or passed through. The electrons in the atoms of the PV cell are energized by the energy of the absorbed light.
How to measure the temperature of photovoltaic cells?
In order to measure the temperature of photovoltaic cells more accurately, temperature sensors are pasted on the surface and back of photovoltaic cells. For the measurement of light intensity on the surface of the photovoltaic cell module, a Tm-207 solar power meter was used to measure the light intensity on the surface of photovoltaic cells.
How does light intensity affect the output power of photovoltaic cells?
According to the data in Table 5, the output power of photovoltaic cells increases gradually with the increase of light intensity. When the light intensity increases to about 700, the output power tends to be saturated; when the light intensity is greater than 650, the growth rate of Pout is less than that of Pin.
