Miyajima Lab
Machine-translated · View original
A lab for solar cells and optical wireless power transmission, developing materials and devices that convert light into electricity.
AboutAbout the lab
Making materials and devices that convert light into electricity.
The Miyajima Lab studies materials and devices that convert light into electricity, and devices that use them.
It works on materials for receivers in optical wireless power transmission, which sends power using blue light, sputtering technology that is gentle on substrates, copper oxide materials, and more.
The lab also puts effort into fundamental research on forming thin films by sputtering.
The former Yamada Group continues research on chalcopyrite-based materials used in thin-film solar cells.
Key terms
- Optical wireless power transmission
- A technology that shines laser or LED light on a receiver, converts it into electricity, and sends power without wires
- Perovskite
- A general term for materials with a crystal structure called the perovskite structure. They have attracted attention in recent years as solar cell materials
- Sputtering
- A method of forming a thin film by bombarding a plate of material with ions so that the atoms knocked out of it deposit on a substrate

ResearchResearch themes
The Miyajima Lab studies materials and devices that convert light into electricity, and devices that use them. Its main themes are receivers for optical wireless power transmission, solar cells, and thin-film fabrication by sputtering.
*Illustrative imageReceivers for Optical Wireless Power Transmission
The lab studies receivers for optical wireless power transmission, which delivers power by light to equipment and underwater devices. To convert blue laser light into electricity efficiently, it searches mainly for perovskite materials.
*Illustrative imageLow-Damage Sputter Deposition
The lab studies a method for making high-efficiency silicon solar cells without using explosive or highly toxic gases. Films are formed by facing-target sputtering, which is gentle on substrates.
*Illustrative imageSolar Cells Using Copper Oxide
This research improves the quality of copper oxide materials so they can be used in solar cells with a low environmental burden.
*Illustrative imagePhosphor Films That Generate Power in Windows
The lab fabricates thin films of quantum-cutting phosphors, which convert ultraviolet to blue light into near-infrared light. Using them, it aims to create solar cells that can generate power in the windows of buildings.
