| 摘要 |
<p>The invention relates to a Luminescent Solar Concentrator system (400) and a method for collecting and concentrating external light, particularly sunlight (λ1,λ2). The external light is collected by a luminescent converter component (410) having a thickness D and a ratio R=ax/ac between the absorption coefficient ax for sunlight and the reabsorption coefficient ac for luminescence light. Due to the luminescent material comprised by said converter component (410), at least a part of the external light is converted into luminescence light. Moreover, light propagating within the converter component (410) is extracted from it at light extraction sites (EX) having distances W≰0.1·R·D from each other. Light extraction components may for example comprise slanted mirroring surfaces (414) and/or optical elements in contact to the converter component.</p> |
