Research & Development (R&D)

R&D Structure

Our R&D system is comprised of "Advanced Technology Research Laboratories", which supervises corporate R&D, and research laboratories in each department. Each of them carries out specialized development. In addition, we established "Research and Development Committee" as the company-wide organization to not only examine the direction of company-wide research and development, strategies, and issues, but also to deepen cooperation among laboratories and to strengthen technological capabilities.

"Idemitsu Kosan Next Generation Material Collaborative Research Center" at the Tokyo Institute of Technology ~Creating a New Value~

On April 1, we opened "Idemitsu Kosan Next Generation Material Collaborative Research Center" at the Tokyo Institute of Technology (Tokodai) Suzukakedai Campus. Since the early 2000s, our company and Tokyo Institute of Technology have been engaged in joint research in a wide range of fields, especially on polymer materials, and have achieved satisfying results, including the development of new fiber and film materials.
The newly established research base will go beyond the current collaborative research. It will drive a large-scale and comprehensive R&D through organization-to-organization collaboration. Combining our company’s strength in developing high-performance materials such as lubricating oils, functional chemicals, electronic materials, and agri-bio, with Tokodai’s advanced academic knowledge and cutting-edge science and engineering technologies related to physics and chemistry, we will work to create next-generation materials and develop our human resources.

Examples of Specific Initiatives

Development of CIS solar cell technology

At the Atsugi Research Center of Solar Frontier K.K., we are engaged in leading-edge research and development related to CIS solar cells, aiming to improve energy conversion efficiency at both the research and commercial production levels, as well as developing new applications and developing advanced next-generation products with market development potential.
In January 2019, a joint research project with the NEDO (New Energy and Industrial Technology Development Organization) led to the achievement of a world record energy conversion efficiency of 23.35% for the cadmium-free CIS solar cell (Cd-Free CIS solar cell)’s cell (about 1 cm2). This record is approximately 0.4 percentage points higher than the highest conversion efficiency of 22.9% (Achieved by our company in November 2017) for cadmium-containing CIS solar cells, and represents the highest conversion efficiency in the world for all CIS solar cells. By applying basic technologies, we are working to lower costs by increasing the output of panels and to deliver environmentally friendly and economical products to customers.

Utilization of Collagen and Mucin Derived from Jellyfish

These days, jellyfish are popular in aquariums because of their beautiful appearance. However, jellyfish may have a negative impact on fisheries and businesses of companies along the coast. The use of jellyfish as a resource is desired worldwide. Jellyfish Research Laboratories, Inc. (Kanagawa Prefecture), the company of our Group, has invented a technology to utilize useful ingredients made from jellyfish. Collagen derived from jellyfish has been confirmed to be effective in promoting the regeneration of epidermis which is considered to be difficult to regenerate, and is expected to be used in the fields of regenerative medicine and beauty treatment. Mucin derived from jellyfish is also expected to have potential as a treatment for knee osteoarthritis. By taking advantage of the characteristics of jellyfish, we will create the future of life science and contribute to the quality of life of people around the world. In addition, This business model for circular economy was introduced in Circular Yokohama, a communication platform where circular economy related initiatives in Yokohama are shared.
