摘要: | 在精细平衡模型(Detailed balance model)中,单接面太阳电池的效率极限在太阳光频谱AM1.5G照射下,可高达33.5%以及聚光后的41%。但在现今的太阳电池中,即便是电池的电性已趋于完美,我们仍远落后于这些极限值,因此,效率的差距应源自于太阳电池本身的光性。近来,由精细平衡模型所推导出的外部出光效率( In detailed balance model, the efficiency of single-junction solar cells can be potentially as high as 33.5% and 41% with concentrators under AM 1.5G illumination. However the best state-of-the-art devices are still far lower than those figures, even the electronic quality is nearly perfect. Therefore the efficiency gap should stem from the light management inside solar cells. Recently, external radiation efficiency ( |
