Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
The efficiency of photovoltaic solar collector deteriorates with increase in cell temperature, which is mostly affected by solar radiation intensity rather than ambient temperature, as incident solar radiations cannot be fully converted into electricity and unconverted solar radiation heats up the photovoltaic cell and increase its temperature.
PV cell efficiency increases with solar irradiance, as the greater number of photons associated with higher solar irradiance creates more electron–hole pairs and consequently more current in the photovoltaic cell.
The PV cell efficiency is the ratio of electric power output to input. You might find these chapters and articles relevant to this topic. Waldemar Kuczynski, Katarzyna Chliszcz, in Renewable and Sustainable Energy Reviews, 2023 When the solar cell is lit, a potential difference occurs between the electrodes.
As the cell temperature increases, reduction in band gap of photovoltaic semiconductor occurs which reduces the voltage generated by each photovoltaic cell. This reduces photovoltaic module power and electrical efficiency . Solar cell temperature and electrical efficiency are inversely related to each other .
In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell. Therefore, conditions under which efficiency is measured must be carefully controlled in order to compare the performance of one device to another.
