How do cell parameters affect the performance of a PV cell?

These cell parameters have a dominant impact on the shape of I – V characteristics of a PV cell at any given illumination intensity and cell temperature and thus decide the values of the performance parameters such as short circuit current ( Isc ), open circuit voltage ( Voc ), curve factor (CF) and efficiency ( η) of the PV cell .

What are spectral characteristics of a photocell?

Spectral characteristics The spectral response characteristics of a general photocell indicate the relationship between the short circuit current and the incident light wavelength under the condition that the incident energy is kept constant. Figure 3. Test circuit for the load characteristic of photocell 3.2. Module of Characteristics Test.

How do I adjust the nanoammeter reading in a photocell?

Keep the exit-slit of the lamp enclosure along the same line and facing the entrance-slit of the phototube enclosure. For the first part of the experiment (Table 5. Close the photocell entrance-slit and adjust the nanoammeter reading to ~ zero using the ‘Zero adj.’ knob.

How to test a silicon photocell?

3.3.2. Open Circuit Voltage Characteristic Test of Silicon Photocell. Under the condition of the Fig2 circuit, the illuminance on photocell is controlled by illumination meter. Adjust illumination to the minimum, connected to the illumination meter, DC power to the minimum, open the illumination meter, at this time the meter readings should be 0.

What is a photocell?

3.1. Work Principle and Basic Characteristics of Photocell Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation which are widely used in the digital camera, optical communication, solar cells and other fields, the photocell is a basic unit of semiconductor photoelectric detector.

How to use a filter in a photoelectric cell?

Place a filter in front of the photoelectric cell. Keeping the voltage constant and position of photocell fixed, increase the distance of lamp from photo-cell in small steps. In case note the position of the lamp r on the optical bench and the current I. The experiment may be repeated with other filters (at least 2 filters).
