Short-Circuit Current
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: the area of the solar ...

Weak Light Characteristic Acquisition and Analysis of Thin-Film Solar Cells
The test surface of the solar cell is flatly placed on a glass plate with the light source vertically irradiating the surface tested of the solar cell from bottom to top. The volt-ampere characteristics of solar cells under different light irradiance are tested by changing the light irradiance of simulated sunlight emitted by the solar simulator.
Calculation & Design of Solar Photovoltaic Modules & Array
When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.
