Introduction To Photocells | PPT

When light is absorbed by the silicon, negatively charged electrons are knocked loose from the silicon atoms, causing them to flow freely and create an electric current. The current and power produced by a photocell depends on the light intensity, surface area exposed to light, and distance from the light source. Photocells produce energy

6 FAQs about [Light receiving area of silicon photocell]

How does a photocell work?

How does the efficiency of a photocell differ from a real photocell?

and the efficiency is Observe that depends only on the spectral distribution and on the of the semiconductor. It completely ignores the manner in which the device operates. Unlike the efficiency of real photocells, does not depend on the level of illumination.

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.

How a photocell module is soldered?

The soldering of cells to the stringing ribbon is carried out by a tabbing machine (using infrared) or by a soldering iron. In the second stage, the photocell clusters are soldered to a “bus ribbon” that carries electric current to the output of the module.

How efficient is a photocell at 6000 K?

Figure 14.4 shows how the ideal efficiency of a photocell depends on the band gap energy when exposed to a black body at 6000 K (about the temperature of the sun). Our efficiency calculations, based on Eq. 14.28, use a very simple model that totally ignores the photocell itself which is assumed to be 100% efficient.

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.
