Different NB materials generate diverse output performance depending on the properties of materials crystal and cell configuration. Decreasing the bandgap of the materials will improve the collection of longer wavelength photons, but that tends to increase the recombination rate and reduce cell efficiency $(eta)$. This paper investigates the performance of NB cells. Silvaco TCAD software was used to simulate the output performance of germanium (Ge), indium arsenide (InAs), gallium antimonide (GaSb), and indium gallium arsenide (InGaAs) cells under solar spectrum AM1.5 and 1000 K illumination spectrums. It was found that InGaAs is the most outstanding material for photovoltaic (PV) application and TPV application at 1000 K radiation temperature. The comparative study and conclusion drawn in this work highlight several limitations in NB cells configuration, such as the high surface recombination rate in GaSb and InAs TPV cell, which reduces photocurrent collection.","PeriodicalId":6758,"journal":{"name":"2020 IEEE 8th International Conference on Photonics (ICP)","volume":"154 1","pages":"42-43"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79755727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The investigated graphene nanoantenna composes of multi-layer graphene stack formation, which is placed above the gold hexagon radiator to efficiently couple activated graphene plasmons. The efficient coupled plasmons between graphene layers and gold hexagon increase the absorption of the antenna. Furthermore, the relationship between the absorption and multi-layer graphene is analysed by changing the Fermi energy of the graphene sheet, thus providing tunability of broadband absorption at a wide range of frequencies. The investigated nanoantenna has a resonant frequency at 30.5 THz with a bandwidth of 0.6 THz, while the trilayer graphene nanoantenna results in better absorption almost reaching 100% with a bandwidth of 2.5 THz. The simulation of the graphene-metal antenna is performed in CST studio by using an FDTD solver.
