An Alternative Metal-Assisted Etching Route for Texturing Silicon Wafers for Solar Cell Applications
Es, Fırat; Kulakçı, Mustafa; Turan, Raşit (IEEE-Inst Electrical Electronics Engineers Inc, 2016)Metal-assisted etching (MAE) can be used to form antireflective and light-trapping structures on crystalline silicon solar cells. This method has been widely used to form nanowires and nanoholes on their surfaces. In this ... -
Growth, Fabrication and Characterization of Quantum Dot Intermediate Band Solar Cell
Serincan, Uğur; Kuru Mutlu, Hülya; Kulakçı, Mustafa (Gazi University, 2017)Stacked layers of self-assembled InAs quantum dots were synthesized within the base region close to the back surface field of GaAs single junction n- on p-solar cell. The solar cell structure was grown epitaxially on p-type ... -
Multi-crystalline silicon solar cells with metal-assisted nano-texturing using HNO3 as hole injection agent
Es, Fırat; Baytemir, Gülsen; Kulakçı, Mustafa; Turan, Raşit (Wiley-V C H Verlag GMBH, 2016)In this study, metal-assisted etching (MAE) with nitric acid (HNO3) as a hole injecting agent has been employed to texture multi-crystalline silicon wafers. It was previously proven that addition of HNO3 enabled control ... -
Performance of solar cells fabricated on black multicrystalline Si by nanowire decoration
Es, Fırat; Çiftpinar, Emine Hande; Demircioğlu, Olgu; Gunoven, Mete; Kulakçı, Mustafa; Turan, Raşit (Elsevier Science BV, 2015)Vertically aligned Si nanowire (NW) arrays fabricated by metal-assisted etching technique were applied to industrial sized (156 mm x 156 mm) multicrystalline Si cells as an anti-reflective (AR) medium. The NW lengths ... -
The quantum confined Stark effect in silicon nanocrystals
Kulakçı, Mustafa; Serincan, Uğur; Turan, Raşit; Finstad, Terje G. (IOP Publishing LTD, 2008)The quantum confined Stark effect (QCSE) in Si nanocrystals embedded in a SiO(2) matrix is demonstrated by photoluminescence (PL) spectroscopy at room and cryogenic temperatures. It is shown that the PL peak position shifts ...
