Tokyo, Japan – June 12, 2012 – Kaneka and imec report a large area (6 inch semi-square) heterojunction silicon solar cell with a certified power conversion efficiency of 22.68%(*) with an electroplated copper contact grid on top of the transparent conductive oxide layer. This breakthrough is achieved at Kaneka Osaka lab using Kaneka’s copper electroplating technology which is based on imec’s state-of-the-art copper electroplating knowhow.

To realize the top grid electrode in heterojunction silicon solar cells, silver screen printing is the preferred technology in the PV (photovoltaic) industry. However, a drawback of this technology is the difficulty to … Read More → "Imec and Kaneka Achieve Breakthrough in Developing Next-Generation Heterojunction Solar Cells"

SAN DIEGO, Calif. – June 6, 2012 – ROHM, in collaboration with Ritsumeikan University and Information  Services International – Dentsu, Ltd. (ISID), recently announced Guidepost Cell™, a unique indoor location detection infrastructure that supplies highly precise positional data to smartphones and other mobile devices to determine a user’s location inside buildings, underground malls and other interior areas using low-power 802.11-compliant wireless beacon protocol.

Demand-Driven Technology

A variety of mobile devices that utilize Global Positioning Systems (GPS) and other outdoor location detection services have been produced in recent years. However, GPS operation is often spotty or non-existent indoors, … Read More → "ROHM Introduces Guidepost Cell—a New Indoor High-Accuracy Location Detection Infrastructure Powered by Energy-Harvesting DSC (Dye-Sensitized Solar Cells)"
