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.
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.
Efficiency is the ratio of output power (pout) to input power (Pin) where the conversion efficiency is the output electric power divided by the result of solar irradiation (E) and the surface area (A) of the solar panel. Multiplying the measured output voltage and current equal to the output power , . ...
From I-V curve the efficiency of the cell is proportional to the value of the three main photovoltaic parameters: short circuit current Isc, open circuit voltage V.c, fill factor FF and efficiency rl have been determined.
The maximum general efficiency calculated is 86.8% for a pile of cells, using the incoming intense sunlight radiation. When the incoming radiation comes only from an area of the sky the size of the Sun, the efficiency limit drops to 68.7%. What types of solar panels are most efficient?
