Does the operating temperature affect the electrical performance of solar cells/modules?

In this paper, a brief discussion is presented regarding the operating temperature of one-sun commercial grade silicon- based solar cells/modules and its effect upon the electrical performance of photovoltaic installations. Generally, the performance ratio decreases with latitude because of temperature.

How does temperature affect solar cell performance?

Solar cell performance decreases with increasing temperature, fundamentally owing to increased internal carrier recombination rates, caused by increased carrier concentrations. The operating temperature plays a key role in the photovoltaic conversion process.

How does low temperature affect a solar cell recombination rate?

For solar cells, low temperature improves open-circuit voltage due to the low recombination rate and temperature-bandgap dependency, but reduces short-circuit current due to the absence of absorption of low-energy photon caused by the increase of bandgap.

What is the difference between a solar cell and a room temperature?

However, solar cells are typically measured almost 2 degrees lower at 25 °C (298.15 K). In most cases, the difference is insignificant (only 4 mV of V oc), and both are referred to as room temperature. Occasionally, the modeled results need to be adjusted to correlate with the measured results.

What factors affect solar cell performance?

One of the main parameters that affect the solar cell performance is cell temperature; the solar cell output decreases with the increase of temperature. Therefore, it is important to select the proper solar cell technology that performs better at a specified location considering its average temperatures.

What temperature should a solar cell be measured at?

Most semiconductor modeling is done at 300 K since it is close to room temperature and a convenient number. However, solar cells are typically measured almost 2 degrees lower at 25 °C (298.15 K). In most cases, the difference is insignificant (only 4 mV of V oc), and both are referred to as room temperature.
