The efficiency of a solar cell (sometimes known as the power conversion efficiency, or PCE, and also often abbreviated η) represents the ratio where the output electrical power at the maximum power point on the IV curve is divided by the incident light power – typically using a standard AM1.5G simulated solar spectrum.
You can use the estimate for the maximum theoretical power to calculate the maximum theoretical efficiency, E, of the solar cell. Here’s how to calculate the efficiency of the solar cell using the sun: First, calculate the solar power arriving at the solar cell by multiplying the intensity of the sun by the area of the solar cell.
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.
Quantum efficiency refers to the percentage of photons that are converted to electric current (i.e., collected carriers) when the cell is operated under short circuit conditions. The two types of quantum that are usually referred to when talking about solar cells are external and internal.
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.
External quantum efficiency (EQE) relates to the measurable properties of the solar cell. The "external" quantum efficiency of a silicon solar cell includes the effect of optical losses such as transmission and reflection. Measures can be taken to reduce these losses.
