6 FAQs about [Photovoltaic cell characterization dark iv]

What is dark current-voltage (dark I-V)?

Abstract: Dark current-voltage (dark I-V) measurements are commonly used to analyze the electrical characteristics of solar cells, providing an effective way to determine fundamental performance parameters without the need for a solar simulator.

Can photovoltaic cells be measured in the dark?

Since solar cells convert light to electricity it might seem odd to measure the photovoltaic cells in the dark. However, dark IV measurements are invaluable in examining the diode properties. Under illumination, small fluctuations in the light intensity add considerable noise to the system making it difficult to reproduce.

Can dark I-V measurements be used for photovoltaic modules?

The work documented here extends the use of dark I-V measurements to photovoltaic modules, illustrates their use in diagnosing module performance losses and proposes their use for process monitoring during manufacturing. Conferences > Conference Record of the Twen...

What parameters of a solar cell can be extracted from IV curves?

Among other significant parameters of the solar cell that can be extracted from the IV curves are the equivalent series and parallel resistances. Figure 4 shows the simplified equivalent circuit model of a solar cell.

Can a poly-Si solar cell be used under dark condition?

These techniques have been adequately modified, extended to cover the case of solar cells and used to extract the parameters of interest from experimental I-V characteristic of a Poly-Si solar cell under dark condition.

Does dark I-V measure short-circuit current?

The dark I-V measurement procedure does not provide information regarding short-circuit current, but is more sensitive than light I-V measurements in determining the other parameters (series resistance, shunt resistance, diode factor and diode saturation currents) that dictate the electrical performance of a photovoltaic device.

Jsc-Voc

A J SC V OC curve1 is a valuable way of looking at an IV curve in the absence of series resistance. To trace a J SC V OC curve, the illumination on a cell is varied and the cell J SC and V OC measured at each illumination level. The series resistance has no effect on the V OC, since no current is drawn from the cell and so there is no voltage drop across the series resistance.
