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 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.
These values are usually based on standard operating conditions of 1000 watts per square meter solar irradiance and cell temperature of 77°F (25°C). The information from a module’s I-V curve is used to rate module performance and to help determine the size of the PV system array. Figure 3. An I-V curve for a common PV module size.
Photovoltaic modules (Figure 2) are interconnected solar cells designed to generate a specific voltage and current. The module's current output depends on the surface area of the solar cells in the modules. Figure 2. A flat-plate PV module. This module has several PV cells wired in series to produce the desired voltage and current.
Part of the Lecture Notes in Electrical Engineering book series (LNEE,volume 878) Since the use location of man-portable photovoltaic power supply, field mobile photovoltaic system and other equipment will change at any time, the impact of light incidence angle on its power generation capacity is extremely significant.
A solar cell is a semiconductor device that can convert solar radiation into electricity. Its ability to convert sunlight into electricity without an intermediate conversion makes it unique to harness the available solar energy into useful electricity. That is why they are called Solar Photovoltaic cells. Fig. 1 shows a typical solar cell.
