6 FAQs about [What are the temperature characteristics of photocells ]
What is a photocell?
A photocell is a resistor that changes resistance depending on the amount of light incident on it. You might find these chapters and articles relevant to this topic. A photocell is a light-to-electrical transducer, and there are many different types available.
What is the temperature range of a solar cell?
Most laboratory-scale cells were tested under standard test conditions (STC, AM 1.5G spectrum, 25 °C, 1000 W m −2), while the outdoor environment generally featured with a fluctuant temperature range of − 20 to 80 °C that is determined by the environmental factors, such as air temperature, solar irradiance and wind velocity , , .
How does a photocell change its resistance?
A photocell or photoresistor is a sensor that changes its resistance when light shines on it. The resistance generated varies depending on the light striking at his surface. A high intensity of light incident on the surface will cause a lower resistance, whereas a lower intensity of light will cause higher resistance.
Why do photocells need a small series resistance?
Under such highly concentrated conditions and hence the existence of elevated current densities, the cells are required to have a sufficiently small series resistance so as to maintain an appropriately high fill factor; otherwise, photocells would suffer further undesired efficiency losses.
How do you calculate the sensitivity of a photocell?
The sensitivity of photocells can be quoted in either of two ways, either as the electrical output at a given illumination, using illumination figures in units of lux, often 50 lux and 1000 lux, or as a figure of power falling on the cell per square centimetre of sensitive area, a quantity known as irradiance.
Is a photocell a light-to-electrical transducer?
A photocell is a light-to-electrical transducer, and there are many different types available. Light is an electromagnetic radiation of the same kind as radio waves, but with a very much shorter wavelength and hence a much higher frequency.
