Evaluation of temperature characteristics of high-efficiency
The light from the solar simulator (light source: Xe lamp) was adjusted for 1 sun (AM 1.5G, 100 mW/cm 2), and was focused by a Fresnel lens.The concentration ratio was defined by dividing the short-circuit current (I sc) under concentrated light by the I sc under 1 sun illumination.The concentration ratio was varied from 1 to 14 suns.The cell was attached to the
