The measurement of the current-voltage (IV) curve is one of the key elements to characterize the performance of solar cells and modules.
A spectral response curve is shown below. The spectral response of a silicon solar cell under glass. At short wavelengths below 400 nm the glass absorbs most of the light and the cell response is very low. At intermediate wavelengths the cell approaches the ideal. At long wavelengths the response falls back to zero.
A contactless method for current-voltage testing of silicon solar cells is proposed. It may reduce cell breakage and costs. It may improve line throughput and light homogeneity and gives extra information. The method combines four contactless measurement techniques. The proof of principle of the method is successfully demonstrated for 3 cell types.
Characteristic curves I-V and P-V of a mono-crystalline silicon solar cell with a cell area of 102 cm 2 . Temperature influence on solar modules electric output parameters was investigated experimentally and their temperature coefficients was calculated. ... a solar cell is in an open-circuit or short-circuit state, it produces no power.
For measuring the IV curve of solar cells, the cells are generally mounted on vacuum chucks, which often contain an active cooling and heating unit to precisely regulate the solar cell temperature to 25 °C. This is particularly important for steady-state simulators, which exhibit a significant heat transfer to the cell.
I–V curves allow identifying certain faults in the photovoltaic module, as well as quantifying the power performance of the device. I–V curve tracers are present in different topologies and configurations, by means of rheostats, capacitive loads, electronic loads, transistors, or by means of DC–DC converters.

Light Generated Current
The generation of current in a solar cell, known as the "light-generated current", involves two key processes. The first process is the absorption of incident photons to create electron-hole pairs. Electron-hole pairs will be generated in the solar cell provided that the incident photon has an energy greater than that of the band gap.
