Semiconductor Tandem Cell Voltage Addition Calculator
Actual equal-series-current subcell voltage sum minus independently measured interconnect loss. Not combine each cells different-current MPPor promise a tandem operating point.
Description
Series-connected tandem-cell voltages add at a common operating current.
Series-connected tandem-cell voltages add at a common operating current.1
Interconnect loss is subtracted separately, so independently measured open-circuit values are not automatically compatible operating voltages.
When to use Semiconductor Tandem Cell Voltage Addition Calculator
Use this tool to obtain conditionalSeriesTandemTerminalVoltage from the supplied records using the stated calculation. Establish the device or material, operating point, units and independently applicable measurement or model calibration.
How to use Semiconductor Tandem Cell Voltage Addition Calculator and understand its results
- Establish the device or material, operating point, units and independently applicable measurement or model calibration.
- Enter independentlyMeasuredSubcellVoltagesAtSameSeriesCurrent, actualInterconnectVoltageLoss, using the field meanings and rules below, then run the tool.
- Read result.conditionalSeriesTandemTerminalVoltage. Use the units and sign conventions below, and review any unknown records separately.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| independentlyMeasuredSubcellVoltagesAtSameSeriesCurrent | Independently measured subcell voltages at same series current | list of number | Required |
| actualInterconnectVoltageLoss | Actual interconnect voltage loss | number | Required |
Supply a nonempty finite list of subcell voltages independently matched at the same series current, plus nonnegative interconnect voltage loss. Individual subcell voltages may be signed. Sum them and subtract loss, preserving a signed terminal voltage. No current matching or maximum-power optimization is calculated.
terminalVoltage=ΣsubcellVoltages−interconnectLoss Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Qualified observed calculation or explicit reference | object |

}Limitations and assumptions
Device structure, material state, operating conditions and calibration determine applicability. The result does not infer missing physical parameters, verify a transport mechanism or validate a fabricated device model.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries, subject to the narrower lengths and code rules above. Extremely large composite outputs are rejected.
