چکیده
We report an indium tin oxide (ITO) free inverted organic solar cell with alternate aluminium doped zinc (AZO) front cathode layer based on the consideration of blocking harmful ultraviolet (UV) rays, which is one prominent reasons for degradation cells. To further enhance power conversion efficiency AZO/ZnO/PTB7:PC71BM/MoO3/Ag cell, plasmonic gold nanoflowers were embedded inside active layer. The critical parameter thickness electron transport (ETL), hole (HTL) and war first optimized through simulations using general purpose photovoltaic device model (GPVDM) software. experimental fabrication desired geometry was then carried out thickness. (PCE) under UV exposure found remarkably constant AZO electrode as compared to conventional ITO This attributed property AZO. PCE boosted from 6.19% 7.01% use Au nanoparticles in AZO/ZnO/PTB7:PC71BM/MoO3/Ag. work provides a practical insight developing free, assisted enhanced stability.

In this article, the effect of plasmonics properties of metal nanorods and nanoparticles on solar cell performance were investigated and simulated. Due to the classic solar cell disadvantages, it seems that a plasmonic solar cell is one of these methods. In plasmonic solar cells, because of plasmonic effect, a high electric field builds around metal nanoparticles so that high conversion efficie...
