The PL, EQE, and J-V characterisation results show a clear relationship between the doping methods and the non-radiative recombination. All doped QDSCs exhibited increase in the V-{mathbf{OC}} due to{reduced thermal coupling from QD Si doping. Delta and modulation-doped QDSCs exhibit further improvements in V-{mathbf{OC}} due to reduced non-radiative recombination. Moreover, the modulation-doped QDSC shows improvements in both the current density and the voltage compared with the directly doped QDSC. date: 2018-11-29 date_type: published publisher: IEEE official_url: https://doi.org/10.1109/PVSC.2018.8548028 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1629756 doi: 10.1109/PVSC.2018.8548028 isbn_13: 9781538685297 lyricists_name: Chan, Shun lyricists_name: Kim, Dongyoung lyricists_name: Liu, Huiyun lyricists_name: Tang, Mingchu lyricists_id: SSCHA28 lyricists_id: DKIMX35 lyricists_id: HLIUX22 lyricists_id: TANGX88 actors_name: Kim, Dongyoung actors_id: DKIMX35 actors_role: owner full_text_status: public publication: 2018 IEEE 7th World Conference on Photovoltaic Energy Conversion, WCPEC 2018 - A Joint Conference of 45th IEEE PVSC, 28th PVSEC and 34th EU PVSEC pagerange: 2759-2762 event_title: 7th World Conference on Photovoltaic Energy Conversion (WCPEC), 10-15 June 2018, Waikoloa Village, HI, USA book_title: 2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC) citation: Kim, D; Chan, S; Tang, M; Wu, J; Liu, H; (2018) The influence of direct, delta, and modulation QD Si doping on InAs/GaAs quantum dot solar cells.
