A Technological Evolution from bulk crystalline age to multilayers thin film age in solar photovoltaics
Renewable Energy, 1998Co-Authors: Yoshihiro HamakawaAbstract:Abstract Recent advances in solar cell device technologies are surveyed, and a new trend underlying is predicted by a term “Technological Evolution from the bulk crystalline age to the multilayered thin film age”. In the paper, firstly, recent progress of thin film fabrication technologies for active materials of photovoltaic device are reviewed, and their significancies such as wide area, low temperature growth etc., are pointed out from currently developed live technologies. Secondly, some R & D efforts to develop the next generation type solar cells utilized by full use of multi-layers thin film growth technology are introduced together with some newly developed integrated process technology for the thin film solar cells. Then, some topics in the high cost performance multi-layers thin film solar cells are also introduced. In the final part of this paper, the current state of the art in the field of thin film solar cells and their industrialization are overviewed and the market expansion toward the 21st century is forecast, and discussed.

A Technological Evolution from bulk crystalline age to multilayered thin film age in optoelectronic devices
Applied Surface Science, 1996Co-Authors: Yoshihiro HamakawaAbstract:A new trend in semiconductor optoelectronics is predicted and discussed in view of a Technological Evolution from the bulk crystalline age to the multilayered thin film age. Firstly, recent progress of thin film fabrication technologies for active materials of optoelectronic devices is reviewed, and their significances such as wide area, low temperature growth etc., are pointed out from currently developed live technologies. Secondly, some new kind of functional devices utilized by the full use of multilayered thin film growth technology is introduced. With the aid of recent advances in microfabrication technology on these multilayered thin films, the development of a new type of display devices such as a tunable color EL display, a full color EL display made of new materials is introduced. In the final part of this paper, the current state of the art in the field of optoelectronics with these newly developed functional devices is reviewed, and their market expansion toward the 21st century is forecast.

Technological Evolution of onshore wind turbines a market based analysis
Wind Energy, 2016Co-Authors: Javier Serranogonzalez, Roberto LacalaranteguiAbstract:Wind energy technology is evolving towards larger machines (longer blades, taller towers and more powerful generators). Scaling up wind turbines is a challenging task, which requires innovative solutions as well as new configurations and designs. The size of wind turbines (in terms of rotor diameter, hub height and rated power) has increased extraordinary from 30 m rotor diameter, 30 m of hub height and 300 kW rated power, usual in the late 1980s, to 92.7 m rotor diameter, 87.7 m of height and 2.1 MW on average at the end of 2014. However, Technological Evolution has not only been focused on the scaling up process but also on developing innovative solutions that minimize costs at the same time as they deal with aspects of different nature, such as grid code requirements, reliability, quality of the wind resource or prices and availability of certain commodities, among others. This paper analyses the Evolution of wind technology from a market-based perspective by identifying trends in the most relevant Technological indicators at the same time as stressing the key differentiating aspects between regions/markets. Evolution and trends in indicators such as rated power, rotor diameter, hub height, specific power, wind class, drive train configuration and power control systems are presented and analysed, showing an intense and fast Technological development, which is enabling wind energy to reduce costs and becoming increasingly more competitive with conventional fuel-based generating technologies. © 2016 The Authors Wind Energy Published by John Wiley & Sons Ltd.
