About Quantum Efficiency Calculator (Formula)

The Quantum Efficiency Calculator is a tool used to calculate the quantum efficiency of a device or system. Quantum efficiency represents the ratio of the number of electrons collected to the number of incident photons. It is a measure of how efficiently a device converts incoming photons into electrons.

The formula used in the Quantum Efficiency Calculator is as follows:

Quantum Efficiency = Number of Electrons Collected / Number of Incident Photons


  • Quantum Efficiency represents the efficiency of converting photons into electrons, expressed as a ratio or percentage.
  • Number of Electrons Collected is the count of electrons collected by the device or system.
  • Number of Incident Photons refers to the total number of photons incident on the device or system.

By dividing the number of electrons collected by the number of incident photons, the calculator provides an estimation of the quantum efficiency.

The Quantum Efficiency Calculator is particularly useful in fields such as photovoltaics, photodetection, and quantum optics. It helps researchers, engineers, and scientists assess the performance of devices or systems that involve the absorption of photons and the generation of electrons. The calculated quantum efficiency serves as a quantitative measure of the device’s ability to convert light energy into electrical current or signal.
