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 value of short circuit depends on cell area, solar radiation on falling on cell, cell technology, etc. Sometimes the manufacturers give the current density rather than the value of the current.
Various factors govern the electricity generated by a solar cell such as; The intensity of the light: Higher sunlight falling on the cell, more is the electricity generated by the cell. Cell Area: By increasing the area of the cell, the generated current by the cell also increases.
For an ideal solar cell at most moderate resistive loss mechanisms, the short-circuit current and the light-generated current are identical. Therefore, the short-circuit current is the largest current which may be drawn from the solar cell. The short-circuit current depends on a number of factors which are described below:
It can be shown that for a high-quality solar cell (low RS and I0, and high RSH) the short-circuit current is: It is not possible to extract any power from the device when operating at either open circuit or short circuit conditions. The values of IL, I0, RS, and RSH are dependent upon the physical size of the solar cell.
The sunlight is a group of photons having a finite amount of energy. For the generation of electricity by the cell, it must absorb the energy of the photon. The absorption depends on the energy of the photon and the band-gap energy of the solar semiconductor material and it is expressed in electron-volt (eV).
The maximum power delivered by the solar cell, Pmax, is the area of the largest rectangle under the IV curve. A commonly used number that characterizes the solar cell is the fill factor, FF, which is defined as the ratio of Pmax to the area of the rectangle formed by Voc and Isc. (1) ( Voc )( Isc )

Solar cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.
Solar cell researchers at NREL and elsewhere are also pursuing many new photovoltaic technologies—such as solar cells made from organic materials, quantum dots, and hybrid organic-inorganic materials (also known as perovskites). These next-generation technologies may offer lower costs, greater ease of manufacture, or other benefits. Further research will see if …

Solar cell maximum power P M depends upon the voltage that it develops across the cell terminal and the current it can supply. 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/m 2), cell''s conversion efficiency in (%), and area of the cell in (m 2). The solar …
The short-circuit current is the current through the solar cell when the voltage across the solar cell is zero (i.e., when the solar cell is short circuited). Usually written as I SC, the short-circuit current is shown on the IV curve below.
When the buck FET is off, the solar cell charges the input cap. When the FET is on, it draws current both from the solar cell and the cap. So while the buck input current is chopped, and the solar cell current is continuous, if voltage on the cap stays constant (ignoring ripple), both currents have the same average value.

The free electrons flow through the solar cells, down wires along the edge of the panel, and into a junction box as direct current (DC). This current travels from the solar panel to an inverter, where it is changed into alternative current (AC) that can be used to power homes and buildings.
