Surface texturing and patterning in solar cells

摘要: Surface texture can perform a number of functions in modern solar cell design. The most obvious function is control reflection from surfaces on which sunlight incident. However, also be used to influence the fate light that refracted into cell. Light steering by surface ensure this absorbed regions are responsive. When with rear reflectors, help trap weakly cell, increasing effective pathlength or optical thickness factors 30-60. Two general types considered. One involves macroscopic features controlled shape designed direction interacting light. other based use irregular size comparable wavelength These very scattering wide range directions. Non-optical uses briefly described. 62 refs., 22 figs.
