After learning the fundamental physics of pn junctions and solar cells in Chapter 3, we are ready to dive further into their electrical characteristics ing known input parameters, such as photocurrent, recombination current, and resistance components, we build a model to compute the response of the solar cell when it is illuminated and electrically biased.
The solar cell parameters are as follows; Short circuit current is the maximum current produced by the solar cell, it is measured in ampere (A) or milli-ampere (mA). As can be seen from table 1 and figure 2 that the open-circuit voltage is zero when the cell is producing maximum current (ISC = 0.65 A).
The cell area is one of the important factors that affect the output power developed by the cell. The value of the output power can be determined for a given input power in (W/m2), cell's conversion efficiency in (%), and area of the cell in (m2). The solar cell efficiency is given under STC and the input power (PIN) is taken as 1000 W/m2.
Through the above research and analysis, it is concluded that the output voltage, current, and photoelectric conversion rate of solar photovoltaic cells are closely related to the light intensity and the cell temperature.
A solar cell efficiency is defined as the maximum output power (PM) divided by the input power (PIN). It is measured in percentage (%), which indicates that this percentage of input sunlight power is converted to electrical power. The input power is power density. Therefore, to calculate efficiency multiply PIN at STC by area.
Points to Remember Current–Voltage Characteristics: Solar cell models should accurately represent the current–voltage (I–V) characteristics of the device under various operating conditions. This includes the open-circuit voltage (Voc), short-circuit current (Isc), and the maximum power point (MPP).
In addition to this, the results showed that the parallel configuration has a larger power output, followed by the individual and series configurations. Additionally, the temperature of the solar panel had a significant effect on the output power of the solar cells. The maximum output power is also affected by temperature variation.
