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.
