Quantum Efficiency Calculator

Formula

The formula to calculate the Quantum Efficiency (Eq) is:

$Eq = \frac{EC}{IP}$

Where:

$Eq$ is the Quantum Efficiency
$EC$ is the number of electrons collected
$IP$ is the number of incident photons

What is Quantum Efficiency?

Quantum Efficiency measures the effectiveness of a photodetector or solar cell in converting incident photons into electrons. It is a crucial parameter in evaluating the performance of these devices, as it indicates how efficiently they can generate electrical current from light.

Example Calculation

Let's assume the following values:

Number of Electrons Collected (EC) = 500
Number of Incident Photons (IP) = 1000

Using the formula to calculate the Quantum Efficiency (Eq):

$Eq = \frac{EC}{IP} = \frac{500}{1000} = 0.5$

The Quantum Efficiency (Eq) is 0.5.
