Welcome to our
Laboratory
Nowadays, Si is mainly used for solar cells. However,
Si-related solar cells have several problems such as high cost,
limited material, complex manufacturing process, and so on. For the
21st century, solar cells are required for high conversion
efficiency, low-cost, lightweight, and radiation-resistance.
Chalcopyrite-structure
CuIn1-xGaxSe2 (CIGS) alloy
semiconductors have attracted attention as a promising candidate for
use in light-absorbing media.
In our laboratory, we have been studied
crystal growth and characterization of several materials for solar
cells. Now, we are studying (1) chalcopyrite
materials CIGS film for solar cells and photocatalyst devices, (2) Earth abandant
materials such as SnS, Cu2SnS3, NiO
for used photoabsorber of solar cells, (3) transparent
conducting oxide (TCO) film for new IoT devices.
Even though researchers have made extraordinary progress
over the years, and improved performance, lower costs and
reliability still remain as major considerations and challenges. We
are striving to produce a uniform single phase absorber layer and a
window layer with better optoelectronic properties which together
will increase the efficiency of solar cell devices. The ultimate
goal of the project is transferring laboratory achievements to the
commercial production line which will have a substantial impact on
the scientific world and technology. We collaborate with several researchers in the world for
these experiments.
