Semiconductor Photodiode Quantum Efficiency Calculator
Infer actual dark-subtracted photodiode photon/electron yield, retain negative/above-one measurement evidence, distinct from forward responsivity formula; no detector calibration guarantee.
Description
Photodiode quantum yield compares collected electrons with incident photons after subtracting dark current.
Photodiode quantum yield compares collected electrons with incident photons after subtracting dark current.1
Photon energy and the charge convention must match the measurement, and a signed result exposes background or calibration inconsistencies.
When to use Semiconductor Photodiode Quantum Efficiency Calculator
Use this tool when you need to calculate the stated measurement summary or conditional model from matched observations. Prepare independently matched device or specimen measurements, units, branch selection, and model or calibration conventions.
How to use Semiconductor Photodiode Quantum Efficiency Calculator and understand its results
- Prepare independently matched device or specimen measurements, units, branch selection, and model or calibration conventions.
- Enter observedIlluminatedCurrentAmps, observedDarkCurrentAmps, observedIncidentOpticalWatts, callerMatchedPhotonEnergyJ, callerElementaryChargeC, following the field table and calculation rules below, then run the tool.
- Read signedDarkSubtractedPhotodiodeQuantumYield. Use the output table and calculation rules below to interpret units, signs, crossings, and flags.
- Correct any input issues and run again. Before using a successful result, review its units, signs, evidence coverage, and stated model or reference assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedIlluminatedCurrentAmps | Observed illuminated current amps | number | Required |
| observedDarkCurrentAmps | Observed dark current amps | number | Required |
| observedIncidentOpticalWatts | Observed incident optical watts | number | Required |
| callerMatchedPhotonEnergyJ | Caller matched photon energy j | number | Required |
| callerElementaryChargeC | Caller elementary charge c | number | Required |
Require nonnegative illuminated and dark currents, positive optical power, photon energy, and elementary charge. Subtract dark current, convert current to electrons per second, and divide by incident photons per second. Negative yields and yields above one are retained rather than clipped.
yield=(Iilluminated−Idark)×Ephoton/(q×P) Read these symbols with the field meanings and branch or reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| signedDarkSubtractedPhotodiodeQuantumYield | Signed dark subtracted photodiode quantum yield | number |

}Limitations and assumptions
Measurements, branch identification, units, and model applicability must be independently established. Results do not supply universal material constants, a complete physical model, or operating-condition approval.
Missing required fields, unknown fields, wrong types, and violated calculation rules return input issues. Numeric values must be finite; nonfinite numeric outputs are rejected.
Alternative or Complementary methods
For a related task, use Semiconductor LED External Quantum Efficiency Calculator: LED external quantum yield compares emitted photons with injected electrons. Matched mean photon energy connects optical power to photon rate and differs from electrical-to-optical power efficiency. For a complementary step, use Semiconductor Photodiode Bandwidth Calculator: Detector bandwidth can be limited by both resistance-capacitance response and carrier transit. An inverse-square combination is an explicit approximation that requires a separately established transit limit.
