1、IEEE Standard Definitions of Terms for SOLAR CELLS INTRODUCTION The purpose of this publication is to provide uniform and acceptable terms for use in the application of solar cells to power systems. The terms shoiild be useful in unifying expressions used in engineering writing and in the preparatio
2、n of specifications arid procurement documents. It is expected that this Standard will be found most useful by persons not expert in the solar cell field as opposed to the scientific use of such terminology. Users of the terms are urged to refer to the IEEE Dictionary for more general definitions. h

IEEE Standard Definitions of Terms for SOLAR CELLS Active Area The illuminated area normal to light incidence, usually the face area less the contact area. For the purpose of determining efficiency, the area covered by collector grids is considere
6、d a part of the active area. Air Mass The mass of air between a surface and the sun that affects the spectral distribution and intensity of sunlight. Air Mass One A term that specifies the spectral dis- tribution and intensity of sunlight on earth at sea level with the sun directly overhead and pass
7、ing through a standard atmosphere. Air Mass Zero A term that specifies the spectral dis- tribution and intensity of sunlight in near-earth space without atmospheric attenuation. Note: The air maw must be specified when reporting the efficiency of solar cells; for example, 10 percent efficient at a i
