WUT Professor Cheng Yibing’s Team Published Review in Nature

  Recently, Professor Cheng Yibing, a professor of the "Thousand Talents Program" of WUT, and his team were invited by Nature magazine to publish a review on Print flexible solar cells (Nature 539, 488-489, 2016, doi: 10.1038 / 539488a). This paper combines the experience of Professor Cheng Yibing and his team in the field for many years, summarizes the advantages and existing problems of the printable solar cells; and they put forward their own views on the future development direction and strategy of the field.

Conventional silicon solar cells account for more than 90% of global production, yet making them uses energy equivalent to about 10% of their lifetime output.

  This paper points out some problems existing in the printable solar cell, such as lack of special printing equipment, insufficient printing accuracy in large area, and instability and toxicity of some battery materials, etc. This needs the joint efforts of researchers, the business community and government officials in different fields to work together to achieve great development in printable solar cell industry.

Roll-to-roll printing of organic photovoltaic cells

  Professor Cheng Yibing is an expert of "Thousand Talents Program" of the State Key Laboratory of Advanced Technology for Materials Synthesis and Processing of WUT, and an Academician of Australian Academy of Engineering. He is an internationally renowned expert in printable solar cells, and has been engaged in the research work of industrialization of printing and manufacturing solar cells for many years. He has successfully developed a 10-meter-long fully automatic printing machine, which can continuously prints flexible dye-sensitized solar cells. The main research direction of the Printing Optoelectronics Laboratory established by Professor Cheng Yibing, is to develop new photovoltaic devices that can be printed, including perovskite, copper, zinc, tin, organic solar cells and so on, at the same time to carry out photoelectron functional film research related to printing. When carrying out technical research, the team is committed to promoting the industrialization of printable solar cells.
