6 FAQs about [What does low resistivity of photovoltaic cells mean ]
Why does a photovoltaic module have a low shunt resistance?
The electrical performance of a photovoltaic (PV) module is greatly hindered by the existence of parasitic resistance losses, such as high series resistance (R s) and low shunt resistance (R sh). Contact resistance at metal grid/semiconductor interface and emitter sheet resistance are two major contributors to cell R s.
What is the characteristic resistance of a solar cell?
The characteristic resistance of a solar cell is the cell's output resistance at its maximum power point. If the resistance of the load is equal to the characteristic resistance of the solar cell, then the maximum power is transferred to the load, and the solar cell operates at its maximum power point.
What causes series resistance in a solar cell?
Series resistance in a solar cell has three causes: firstly, the movement of current through the emitter and base of the solar cell; secondly, the contact resistance between the metal contact and the silicon; and finally the resistance of the top and rear metal contacts.
Does series resistance affect a solar cell at open-circuit voltage?
Series resistance does not affect the solar cell at open-circuit voltage since the overall current flow through the solar cell, and therefore through the series resistance is zero. However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance.
How does series resistance affect the IV curve of a solar cell?
However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance. A straight-forward method of estimating the series resistance from a solar cell is to find the slope of the IV curve at the open-circuit voltage point.
How does a shunt resistance affect a solar cell?
The effect of a shunt resistance is particularly severe at low light levels, since there will be less light-generated current. The loss of this current to the shunt therefore has a larger impact. In addition, at lower voltages where the effective resistance of the solar cell is high, the impact of a resistance in parallel is large.
