In this paper, solar cells made of thin silicon and copper-indium-gallium-selenide (CIGS) were tested under different light incidence angles, and the volt-ampere charac-teristics of the same cells under different conditions were compared and investigated.
Research of volt-ampere characteristics testing method for photovoltaic cells Abstract:Volt-ampere characteristic(I-V) curve is one of the most important characteristics of solar arrays, and is an indispensable reference for field performance testing and designing of concentrating photovoltaic power generation system.
In a PV characteristic there are basically three important points viz. open circuit voltage, short circuit current and maximum power point. The maximum power that can be photo current cell saturation of dark current 1.6 x 10-19 C charge of an electron. the cell’s working temperature an ideality factor Shunt resistance Series resistance III.
The IV curve of a solar cell is the superposition of the IV curve in the dark with the light-generated current. Illumination shifts the IV curve down into the fourth quadrant where power can be extracted from the diode. Illuminating a cell adds to the normal "dark" currents in the diode so that the diode law becomes:

Silicon PV cells are composed of a thin layer of bulk Si or a thin Si film connected to electric terminals. One of the sides of the Si layer is doped to form the p–n junction. A thin metallic grid is placed on the Sun-facing surface of the semiconductor. Fig. 2 roughly illustrates the physical structure of a PV cell.
