Title   Temperature Characteristics of Solar Cells

 Abstract The current global energy crisis worsening, therefore, in recent years, with emerging solar power industry is developing rapidly and powerful. Which, especially in single-junction solar cells and multi-junction solar cell conversion efficiency of photovoltaic cells represented continuously made new breakthroughs. Curr traditional energy sources such as oil, coal and other problems already facing depletion. Thereent solar cell there is a common drawback is the conversion efficiency is low, especially for satellites, spacecraft and other space applications. High conversion efficiency of solar cells is unquestionable benefits, because of the site area of exception is limited. Current research focus is also called multi-junction solar cells solar cells in series, InGaN In component by changing the band gap can be achieved from the continuous change 0.7EV to 3.4EV. Specifically, single-junction and multi-junction solar cells as well as the outside temperature changes in the sun under the influence of temperature changes, the main material parameters will be some changes, for this situation, the paper through experiments and the development of an effective simulation model, its the physical mechanism of internal discussion and research, and gives the change of the external heat carrier and the experimental data on the solar impact report. Also on the various parameters of the refractive index and extinction coefficient K N model is the focus of this sub-study.
