We report on fabrication of plasmonic interfaces consisting of Ag nanoparticles on flat and textured Al:ZnO for use at the front surface of thin film solar cells to enhance light trapping and photo-conversion efficiencies. We show that outstandingly high transmittance haze is achieved from single step HCl surface textured Al:ZnO and demonstrate Ag dewetting on textured and flat Al:ZnO surfaces upon annealing at moderate temperatures. Optical response of these plasmonic interfaces clearly display plasmonic resonances in the visible and near infrared, which is crucial for enhancement of photovoltaic conversion efficiency in thin film solar cells.

Plasmonic-photonic arrays with aperiodic spiral order for ultra-thin film solar cells Trevino, Jacob; Forestiere, Carlo; Dİ MARTİNO, Giuliana; Yerci, Selçuk; Priolo, Francesco; Dal Negro, Luca (2012-05-07) We report on the design, fabrication and measurement of ultrathin film Silicon On Insulator (SOI) Schottky photo-detector cells with nanostructured plasmonic arrays, demonstrating broadband enhanced photocurrent generation using aperiodic golden angle spiral geometry. Both golden angle spiral and periodic arrays of various center-to-center particle spacing were investigated to optimize the photocurrent enhancement. The primary photocurrent enhancement region is designed for the spectral range 600nm-950nm, w...
Low temperature crystallization of amorphous silicon by gold nanoparticle Karaman, M.; AYDIN, MURAT; Sedani, S. H.; ERTÜRK, KADİR; Turan, Raşit (Elsevier BV, 2013-08-01) Single crystalline Si thin film fabricated on glass substrate by a process called Solid Phase Crystallization (SPC) is highly desirable for the development of high efficiency and low cost thin film solar cells. However, the use of ordinary soda lime glass requires process temperatures higher than 600 degrees C. Crystallization of Si film at around this temperature takes place in extremely long time exceeding 20 h in most cases. In order to reduce this long process time, new crystallization techniques such a...
Dependence of plasmonic enhancement of photocurrent in a-Si:H on the position and thickness of SiNx spacer layers Saleh, Zaki M.; Nasser, Hisham; Ozkol, Engin; Bek, Alpan; Turan, Raşit (2015-04-29) Plasmonic interfaces integrated to the front, back and both surfaces of photovoltaic thin films show different degrees of enhancement of light trapping. Enhancements in the spectral dependence of photocurrent normalized to the power of excitation light are used as an indicator of enhanced light trapping. In a previous study, we obtained enhancement in the spectral range of 600-700 nm by integrating 100-nm Ag nanoparticles to the back surface of a-Si:H with a critical dependence on the SiNx spacer layer thic...
Advanced light trapping interface for a-Si:H thin film Nasser, Hisham; Saleh, Zaki M.; Ozkol, Engin; Bek, Alpan; Turan, Raşit (2015-04-29) Surface texturing of transparent conducting oxides and plasmonic interfaces are two important techniques used separately in thin film solar cells to reduce reflection and enhance light-trapping. In this study, we merge the effects of Al:ZnO surface texturing and Ag nanoparticles (AgNPs) plasmonics in a single light-trapping interface to investigate their combined light trapping efficiency on a-Si:H thin film. Light scattered by this interface is optimized by placing a thin SiO2 spacer layer between AgNPs an...
