Volt-ampere characteristic testing system of solar cell photovoltaic device

Abstract

A volt-ampere characteristic testing system of a solar cell photovoltaic device belongs to a photoelectric testing device and solves problems that an existing testing system needs to set irradiance through manual operation, and irradiance determining and sample battery testing cannot be carried out simultaneously. The volt-ampere characteristic testing system comprises a sunlight simulator, an irradiance choosing device, an irradiance determining device, a battery testing device and a computer. The sunlight simulator is composed of a an xenon lamp on an optical path and filtering sheets with air quality of 1.5, and the irradiance choosing device and the irradiance determining device are sequentially arranged on an output optical path of the solar simulator. A direct current voltage source supplies power to the irradiance choosing device and irradiance determining device. The battery testing device is connected with the computer through a general purpose interface bus. The volt-ampere characteristic testing system is simple in assembly, fast and easy to operate, all required devices and components can be bought at the market, elements can be acquired easily, and the volt-ampere characteristic testing system can accurately and automatically give out a characteristic curve in real time.

Description

technical field [0001] The invention belongs to a photoelectric test device, in particular to a test system for the volt-ampere characteristic of a photovoltaic device of a solar battery. Background technique [0002] It is estimated that by 2050, the earth's population will reach 12 billion, and with economic growth, the total global energy consumption will be 28TW. At present, the global consumption is about 14TW, and the energy gap is 14TW. Therefore, there is an urgent need for low-cost, high-efficiency photovoltaic cells to meet future energy demands. [0003] Dye-sensitized solar cells are a new type of solar cells developed by imitating the photosynthesis principle of green plants. There is no pollution and toxicity in the process of production, production and use. The notable feature of the battery is that it can convert visible light passing through the glass panel into electricity from all angles, such as for driving a fan. Different from the working principle ...
