Abstract
نقاط كوانتومي كلوييدي تركيبات نيمه هادي با اثرات كوانتومي مي باشند. در اين مقاله تاثير ضخامت لايه نازك از PbS بر روي عملكرد فوتوولتاييك در سلول هاي خورشيدي مورد بررسي قرار گرفت. نقاط كوانتومي PbS در حلال ا-اكتادكان و اولييك اسيد به عنوان عامل پوشاننده سنتز شدند. نتايج بررسي ها نشان داد كه در صخامت 50nm بالاترين بازده (0.66) حاصل مي شود.
Abstract
Colloidal quantum dots offer broad tuning of semiconductor band
structure via the quantum size effect. In this paper, we present a
detailed investigation on the influence of the thickness of colloidal
lead sulfide (PbS) nanocrystals (active layer) to the photovoltaic
performance of colloidal quantum dot solar cells. The PbS
nanocrystals (QDs) were synthesized in a non-coordinating solvent,
1-octadecene, using oleic acid (OA) as the ligand. It was found that
the device with 50 nm of thickness of active layer showed a high
Efficiency (?) of 0.667 under simulated Air Mass 1.5 Global (AM
1.5G) irradiation (100 mW/cm2
) compared to the device with low
thickness of active layer.
