Achieving high performance in optoelectronic devices using semiconductor nanostructures.
Keywords: Semiconductor nanostructures, high-efficiency solar cells, crystal growth, spectroscopic measurements.
We are conducting research to enhance the performance of optoelectronic devices using semiconductor microstructures at the nanometer scale (one billionth of a meter). For example, by utilizing structures called "quantum dots," which confine electrons in three-dimensional space within a very narrow region of about a dozen nanometers in a semiconductor, we can artificially adjust the energy of the confined electrons, thereby exhibiting excellent properties. By arranging numerous quantum dots within solar cells, these quantum dots can absorb light in wavelength ranges that are typically not absorbed, allowing us to efficiently convert the energy from sunlight, which has a broad spectrum, into electricity, significantly improving power generation efficiency. Such semiconductor nanostructures are expected to be applied not only in high-efficiency solar cells but also in high-brightness light-emitting devices and high-sensitivity sensors. To utilize them as actual devices, it is necessary to precisely control the shape, size, uniformity, and arrangement of the nanoscale structures and to fabricate them at high density, for which we are developing high-precision fabrication techniques for microstructures. Additionally, we are evaluating the properties of these materials using various spectroscopic measurement techniques.
