6 FAQs about [Solar cell photovoltaic probe row use]

How accurate is the Binning accuracy of solar cells?

For the evaluated moderate and low V oc cell, the contactless and contacted IV curves match almost precisely. The binning of the solar cells based on the contactless efficiency η works well. A binning accuracy of significantly more than 90% could be achieved with the contacted measurement as reference.

How do you calibrate a solar cell?

For the calibration of a solar cell, the cell area, the spectral responsivity (SR) and the current–voltage (I–V) curve have to be determined. The I–V curve then yields the characteristic parameters, including the power conversion efficiency, fill factor, short-circuit current and open-circuit voltage.

The contacting to the solar cell is implemented as a four-wire configuration. A four-quadrant power supply is used for the measurement of the solar cell I–V curve. The current is measured by means of a voltage measurement across calibrated high-power precision shunt resistors.

How to perform I-V sweep of a PV cell?

The I-V sweep of a PV cell can be accomplished from either the front panel or over the bus. Just a few key strokes are needed to generate, graph, and save the data to a USB drive. Here are the three easy steps to generate and graph a voltage sweep and then save the data to a USB drive. Step 1. Creating and Executing an I-V Sweep Step 2.

How does a solar cell work?

A transimpedance amplifier developed in-house keeps the solar cell under short-circuit conditions and outputs a voltage signal proportional to the current generated by the monochromatic light. The output signal is then measured with a lock-in amplifier. WPVS reference solar cells calibrated at the PTB are used for calibrating the DSR facility.
