6 FAQs about [Weak light characteristics of photovoltaic cells]
What are the disadvantages of photovoltaic cells?
Photovoltaic cells have several disadvantages: Energy from the sun is intermittent and unpredictable and can only be harnessed in the presence of sunlight. Also, the power generated gets reduced during cloudy weather. Long-range transmission of solar energy is inefficient and difficult.
Why do photovoltaic cells respond better to light?
The shorter the wavelength of incident light, the higher the frequency of the light and the more energy possessed by ejected electrons. In the same way, photovoltaic cells are sensitive to wavelength and respond better to sunlight in some parts of the spectrum than others.
What are the voltage characteristics of a photovoltaic cell?
The temperature characteristics of the voltage, <i>I-V</i>, for a photovoltaic cell are measured from 25°C to 87°C and at different illumination levels from 400 to 1000 W/m<sup>2</sup>. This is due to locations where the upper limit of the photovoltaic cells working temperature exceeds 80°C.
Are photovoltaic cells sensitive to sunlight?
Photovoltaic cells are sensitive to incident sunlight with a wavelength above the band gap wavelength of the semiconducting material used manufacture them. Most cells are made from silicon. The solar cell wavelength for silicon is 1,110 nanometers. That's in the near infrared part of the spectrum.
What are the I-V characteristics of a photovoltaic cell?
The I-V characteristics of a photovoltaic cell are measured at different temperatures from 25°C to 87°C, under various levels of illumination. The levels of illumination range from 400 W/m² to 1000 W/m².
How strong are photovoltaic cells?
Photovoltaic cells are very robust in construction and produce a photocurrent sometimes stronger than other photosensitive elements. The typical photocurrent produced by these cells is as high as 120 mA/lumen.
