Introduction to Solar Cells

The position of MPP in series and parallel combinations is shown in Fig. The output resistance of a solar cell at its MPP is called its characteristic resistance (R CH).

6 FAQs about [Solar cell parallel resistance setting]

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 is the relationship between parallel resistance rP and solar cell temperature?

where TRS1 is the Temperature exponent for Rs, TRS1 parameter value. The block provides the following relationship between the parallel resistance Rp and the solar cell temperature T: R p (T) = R p * (T T m e a s) T R P 1 where TRP1 is the Temperature exponent for Rp, TRP1 parameter value.

How do you calculate the resistance of a solar cell?

The characteristic resistance of a solar cell is the inverse of the slope of the line, shown in the figure above as V MP divided by I MP 1. For most cells, R CH can be approximated by V OC divided by I SC: R C H = V M P I M P ≈ V O C I S C R CH is in Ω (ohms) when using I MP or I SC as is typical in a module or full cell area.

What causes shunt resistance in a solar cell?

Shunt resistance (R s h) is created due to leakage currents produced at the edge of the f-PSCs and the imperfection of the cell structure . This affects the parallel conductivity of a solar cell depending on the cell junction [, , , ]. As leakage currents increase, the efficiency of any solar cell decreases.

How do solar cells operate at a 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. It is a useful parameter in solar cell analysis, particularly when examining the impact of parasitic loss mechanisms.

How do I model a number of solar cells connected in series?

You can model any number of solar cells connected in series using a single Solar Cell block by setting the parameter Number of series-connected cells per string to a value larger than 1. Internally the block still simulates only the equations for a single solar cell, but scales up the output voltage according to the number of cells.
