Conference Introduction

The 2023 Chinese Flexible and Printed Electronics Symposium (Flex China 2023) is to be held in Suzhou on 1-2 March 2023

Printed electronics uses printing technologies to make flexible and large area electronic and optoelectronic devices and systems. It is a green manufacturing process and has become a new paradigm in electronic manufacturing. Printing is already adopted in OLED/QLED display panels production, printing is becoming one of the mainstream technologies for making sensors for IoT. Printing is changing the way the printed circuit board (PCB) are made. Smart packaging based on printed electronics will have great impact on traditional printing and packaging industries. Printed electronics on variety of flexible substrate materials such as plastics, papers, textiles or stretchable materials will enable wide range of form factors for electronic products, therefore, open up vast possibilities of new applications.

China started its own printed electronics development in 2010 and held the first symposium that year. Since then, the symposium has been held for 12 consecutive years, including 2 international conferences (ICFPE 2014 and 2018) hosted in China. These symposiums have stimulated the interests of Chinese researchers and industrialists to get involved in the field. From 2017, the Symposium became one of the SEMI’s global FlexTech meeting series and branded as “Flex China”. SEMI is the international organization for semiconductor industries. By forming the alliance with SEMI, the symposium became international. It also reflected the global trend of combining integrated circuit (IC) with printed electronics to enable practical applications of flexible electronics.

The 2023 Chinese Flexible and Printed Electronics Symposium (Flex China 2023) will again be held in Suzhou on 26-27 October. Built on its previous success, the Flex China 2023 will continue to serve as a platform for the exchange of information and progress in the field of flexible & printed electronics.

The Flex China 2023 is under the umbrella of the 2023 China Nano Conference & Expo (Chinano), with several other events in parallel to be held in the same time and at the same venue. For more information about Flex China 2023 and other parallel events, please visit the Chinano website:

Design of interface materials for printable organic photovoltaics

      BiographyProfessor at the National Center of Optoelectronics. Research in printable organic photovoltaics with special focuses on flexible transparent electrodes, molecular interface of high/low work function and applications. Published over 150 papers with citations of 8900 and H-factor 51.

      AbstractOrganic photovoltaics can be fabricated by printing and mechanically flexible, but difficult to realize high efficiency. The key problem is the deposition of dense and uniform films and efficient charge transport between films. This talk will focus on the design of charge transport layers, particularly the hole transport via PEDOT:F which can overcome the problems of traditional PEDOT:PSS, such as acidic, absorbing moisture and hydrophobicity, and the PEI-Zn of low work function of conductive polymer for electron transport. With these new charge transport materials, all-printed organic photovoltaic with efficiency over 13% has been realized.
