### Short-circuit current model of organic solar cells

In organic solar cells, short-circuit current (ISC), which is equal to the photocurrent when the voltage across solar cell is zero, is one of the key parameters of power conversion efficiency Short circuit photocurrent The short-circuit current (ISC) is the current through the solar cell when the voltage across the solar cell is zero (i.e., when the solar ce ll is short circuited). Usually written as I SC, the short-circuit current is shown on the IV curve below. ISC is due to the generation and collection of light -generated carriers Solar cell short circuit current.

In this video, I define several important values for characterizing a solar cell. These include the short circuit current (Jsc), open circuit voltage (Voc),. Similarly, when the cell is operated at short circuit, V = 0 and the current I through the terminals is defined as the short-circuit current. It can be shown that for a high-quality solar cell (low R S and I 0, and high R SH) the short-circuit current I SC is: 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 (I SC = 0.65 A). The value of short circuit depends on cell area, solar radiation on falling on cell, cell technology, etc

short-circuit current is the maximum output current with 0 ohm load. Assuming the V-I curve (graph of voltage output vs current output) is linear, then the source impedance is 4.5V / 18mA = 250ohms. In other words, this solar cell behaves like a 4.5V battery with 250 ohms in series Short-circuit current The solar_generation object also calculates the ideal short-circuit current density (Jsc) by assuming all of the photo-generated electron-hole pairs contribute to the actual photo-current. The short circuit current (Jsc) in this example is around 200 A/m 2 (20 mA/cm 2)

When the light is on, you will measure the largest current. The current you have now measured is called the short circuit current of the solar cell. It is the maximum current that the solar cell can produce. Note the short circuit current Power delivered by the PV cell is the product of voltage (V) and current (I). At both open and closed circuit conditions the power delivered is zero. At some point in between (around the knee point) the delivered power is a maximum. Note: the maximum amount of current that a PV cell can deliver is the short circuit current Where the short-circuit current (I SC) decreases with increasing bandgap, the open-circuit voltage increases as the band gap increases. In an ideal device the V OC is limited by radiative recombination and the analysis uses the principle of detailed balance to determine the minimum possible value for J 0 The short-circuit current density Jse that can be obtained from the standard 100 mW/cm 2 solar spectrum (AM1.5) is determined, on one hand, by optical losses, i.e., by the fact that photons from a part of the spectrum are either not absorbed in the solar cell or are absorbed without generation of electron-hole pairs
