Equivalent Circuit Photovoltaic Solar Cell Performance Models The “five-parameter model” is a performance model for photovoltaic solar cells that predicts the voltage and current output by representing the cells as an equivalent elec-trical circuit with radiation and temperature-dependent components. By continuing you agree to the use of cookies. A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. Now the diode is placed right after the solar cell so Q1 and Q2 are powered by the battery. Maximum Power - this is the maximum power out put of the PV module (see I-V curve below) 2. The most commonly used equivalent circuit in PV is the one diode model. The performance of PV devices is often times modeled with equivalent circuits. Author to whom correspondence should be addressed. These two elements correspond to generation and loss of photocurrent in the device. 4 Solar cell I-V characteristics It possible to calculate the I-V characteristics of the solar cell by considering its equivalent circuit. Model’s Equation Solution In Figure1, the basic schematic diagram of the lumped-parameter equivalent circuit model proposed by Mazhari consists of three diodes and a photo-generated current source without any series or shunt resistances. 1 (ignoring the dashed section): it essentially consists of a current source shunted by a diode. There are two conditions of interest for the actual PV and for its equivalent circuit, which are: 1. Shockley, W. The theory of p-n junctions in semiconductors and p-n junction transistors. The ideal current source delivers current in proportion to the solar flux to which it is exposed.

From the equivalent circuit it is evident that the current produced by the solar cell is equal to that produced by the current source, minus that which flows through the diode, minus that which flows through the shunt resistor: I = IL − ID − ISH. Modeling and simulation techniques are presented at both the circuit and device levels. Dye-sensitized solar cells Engineering & Materials Science If you want to carefully analyze the behavior of a circuit that includes a solar (aka photovoltaic, or PV) cell, you need to use an “equivalent circuit”—i.e., you need to replace the cell with a group of basic components that can produce similar electrical behavior.
