2D materials have been widely studied over the past decade for their potential applications in electronics and optoelectronics. In these materials, elemental composition plays a critical role in defining their physical properties. Here we report the first successful synthesis of individual high quality CuIn 7 Se 11 (CIS) ternary 2D layers and demonstrate their potential use in photodetection applications. Photoconductivity measurements show an indirect bandgap of 1.1 eV for few-layered CIS, an external quantum efficiency of 88.0 % with 2 V bias across 2 µm channel with and a signal-to-noise ratio larger than 95 dB. By judicious choice of electrode materials, we demonstrate the possibility of layered CIS-based 2 2D photovoltaic devices. This study examines this ternary 2D layered system for the first time, demonstrating the clear potential for layered CIS in 2D material-based optoelectronic device applications.

“…For polymers, the development of high-efficiency cells seemed difficult because of the requirement of a low CIGS deposition temperature imposed by the thermal sensitivity of poly imide. A first report from ISET in 1996 announced an ef ficiency of 8.7% obtained by a two-step process of sputtering metal precursors at low temperature followed by a seleniza tion reaction at a higher temperature [47]. Our laboratory, while working at ETH Zurich, reported a record efficiency of 12.8% in 1999 using a coevaporation method, and since then, it has continuously improved setting a new record value of 18.7%, in 2011 [5], [55].…”

Solar cells based on chalcopyrite Cu(In, Ga)Se2 (CIGS) absorber layers show the highest potential for low-cost so lar electricity by yielding comparable efficiencies to polycrystalline Si wafer-based cells, while also offering inherent advantages of thin-film technology for cost reduction. Highest efficiency of 20.3% was recently achieved on rigid glass substrate. Deposition of CIGS films onto flexible substrates opens new fields of applications and could significantly decrease production costs by employing roll to-roll manufacturing and monolithic integration of solar cells to develop modules. Whereas, some years back, it seemed difficult to reach performance levels on flexible substrates similar to that obtained on glass, recent results on flexible polyimide prove that the efficiency gap can be significantly reduced. Different materials, i.e., mostly metals or plastics, have been used as flexible substrates, with highest cell efficiency of 18.7% demonstrated on a polyimide film. Improvements in efficiencies of flexible solar cells and mod ules achieved over the past few decades are discussed in this paper, addressing the main characteristics of substrate materials. The technology transfer from laboratory research to large-scale indus trial production of CIGS modules leads to new manufacturing challenges, mainly for CIGS deposition, interconnections of cells, and long-term performance stability.

Electrospray deposition is fast finding application in the field of thin film device manufacturing processes. The ease and cost efficiency attached to electrospray deposition with possible integration with roll-to-roll fabrication lines is the potential future of thin film device manufacturing. In this study thin films composed of copper-indium-diselenide, more commonly known as CIS, have been made using the electrospray deposition of nano-particle based inks for the ultimate manufacture of CIS-based solar cells. It is the first time that a complete CIS layer has been deposited through electrospray in a single step without involving any other process. Deposited layers are thoroughly characterized using techniques such as scanning electron microscope, Xray diffraction and X-ray photoelectron spectroscopy. Moderate voltage requirements, dense, large grained, *1 lm thick layers and reasonable sintering temperatures involved in the electrospray deposition process promise the possible applicability of electrospray deposition in the manufacturing of cheap and easy to build solar cells.
