Solar cells experience daily variations in light intensity, with the incident power from the sun varying between 0 and 1 kW/m 2. At low light levels, the effect of the shunt resistance becomes increasingly important.
In this paper the low light performance of solar cells and modules is investigated with a simple approach. Only three parameters (1) the series resistance, (2) the shunt resistance and (3) the ideality factor are used similar as it was already shown by Grunow et al. in 2004.
(Hammond 1977) The visible radiation in solar light can be utilized directly in a photovoltaic cell to produce electricity. In Greek, ‘photo’ means light, and a photovoltaic device converts light (photo) energy into electrical voltage.
Light causes the charges to move, producing an electric current. Materials containing different impurities change the wavelengths at which the cell responds in different ways. The photovoltaic cell doesn't convert all the light, even if it's at the right wavelength. Some of the energy becomes heat, and some reflects off the cell's surface.
According to the data in Table 5, the output power of photovoltaic cells increases gradually with the increase of light intensity. When the light intensity increases to about 700, the output power tends to be saturated; when the light intensity is greater than 650, the growth rate of Pout is less than that of Pin.
The experimental results show that the open circuit voltage, short-circuit current, and maximum output power of solar cells increase with the increase of light intensity. Therefore, it can be known that the greater the light intensity, the better the power generation performance of the solar cell. 1. Introduction
