A solar simulator (also artificial sun) is a device that provides illumination approximating natural sunlight. The purpose of the solar simulator is to provide a controllable indoor test facility under laboratory conditions, used for the testing of solar cells, sun screen, plastics, and other materials and devices. ==Classification== The IEC 60904-9 Edition2 and ASTM E927-10 standards are a common specification for solar simulators used for photovoltaic testing. The light from a solar simulator is controlled in three dimensions: # spectral content # spatial uniformity # temporal stability Each dimension is classified in one of three classes: A, B, or C. The specifications required for each class are defined in Table 1 below. A solar simulator meeting class A specifications in all three dimensions is referred to as a Class A solar simulator, or sometimes a Class AAA (referring to each of the dimensions in the order listed above).〔 The solar simulation spectrum is further specified via the integrated irradiance across several wavelength intervals. The percentage of total irradiance is shown below in Table 2 for the standard terrestrial spectra of AM1.5G and AM1.5D, and the extraterrestrial spectrum, AM0. These specifications were primarily intended for silicon photovoltaics, and hence the spectral range over which the intervals were defined was limited mainly to the absorption region of silicon. While this definition is also adequate for several other photovoltaic technologies, including thin film solar cells constructed from CdTe or CIGS, it is not sufficient for the emerging sub-field of concentrated photovoltaics using high-efficiency III-V semiconductor multi-junction solar cells due to their wider absorption bandwidth of 300–1800 nm. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Solar simulator」の詳細全文を読む スポンサード リンク
