Basic parameters of solar cell structure

What are the main parameters of a solar cell?

We will now: Discuss in more detail, whilst using the corresponding equations, the functioning of a solar cell; the goal here is to look at the main parameters of the solar cell: short-circuit current density Jsc, open-circuit voltage Voc, Fill Factor FF and efficiency η.

What are the parameters of a solar cell under STC?

Under STC the corresponding solar radiation is equal to 1000 W/m2 and the cell operating temperature is equal to 25oC. The solar cell parameters are as follows; Short circuit current is the maximum current produced by the solar cell, it is measured in ampere (A) or milli-ampere (mA).

What is the spectrum of a solar cell?

the spectrum of the incident light. For most solar cell measurement, the spectrum is standardised to the AM1.5 spectrum; the collection probability of the solar cell, which depends chiefly on the surface passivation and the minority carrier lifetime in the base.

What are the characteristics of a solar cell?

Material Characteristics: Essential materials for solar cells must have a band gap close to 1.5 ev, high optical absorption, and electrical conductivity, with silicon being the most commonly used.

What is the ideality factor of a solar cell?

The ratio of the measured slope and 60 mV per decade is called the ideality factor and is equal to one for an ideal solar cell. The ideality factor is usually on the order of 1.1–1.3 for c-Si solar cells. The value of I0 is also found from the

What are the standard test conditions for solar cells and PV modules?

The standard test conditions (STC; AM1.5 with 1000 W/m2 and T of the solar cell 25◦C) are the common standard for the characterization of the η of solar cells and PV modules (IEC, 2008). sun simulator is an artificial light source with an intensity spectrum very close to that of the sun at AM1.5.
