Improvement of silicon solar cell efficiency

We are working on anti-reflection of light on the surface of solar cells by forming nano- and sub-micron texture structures on silicon surfaces. When noble metal nanoparticles are applied onto silicon and dipped in an etching solution, the noble metal catalyzes the etching of silicon to form a textured structure. We are working to reduce the reflectance of the silicon surface by such a simple process, and are examining the application to the solar cell fabrication process.

Microfabrication of semiconductors

We are developing silicon microfabrication technology using an inexpensive oil-based ink as a mask.

Formation of high quality silicon oxide film using reaction of organosilicon polymer and low concentration ozone

The thin film transistor (TFT) is manufactured at a low temperature using an original method. We are working on application to TFT process by forming high quality silicon oxide film at low temperature and high speed by reaction of organosilicon polymer (silicone oil) and low concentration ozone.

Operation analysis of various solar cells using equivalent circuit

Development of an equivalent circuit that can express the structure of ultra-high efficiency multijunction solar cells in detail. We are working on design for high efficiency by reproducing solar cell characteristics under concentration and various conditions by circuit calculation using SPICE (Simulation Program with Integrated Circuit Emphasis).
