Researchers from UB University have unveiled new materials which promise to increase the efficient of semiconductor applications. The new materials are films consisting barium zirconium sulphide (BaZrS3). The material promises better optical and electronic properties than conventional materials.
The new films proved better for light-emitting diodes (LEDs), and photovoltaic. The materials depicted strong light absorption capability, and good charge transport. This is essential for applications like solar cells. Current solar cells in the market display between 15-18% efficiency. The new ones promise to replace silicon-based materials with identical materials.
Additionally, the BaZrS3 are also available in abundant quantities in nature. This is important for lowering costs for a large-scale manufacturing. Moreover, the efficiency rates can be increased further with pure varieties of the material, which proved costly to use for researchers.
The study published in the journal Nano Energy in November 2019 provides a completely new direction to future research in semiconductors. Currently, the BaZrS3 are produced in powder quantities by a few firms in the Niagara Fall area. However, its promising future application will require film-variety which will be essential for application like LEDs.
The material, BaZrS3 has been around for decades. The material remained popular due to theoretical belief in its promise. However, the new study funded by US Department of Energy, and National Science Foundation, have brought the promise to its realization. PhD students Xiucheng Wei and Haolei Hui authored the final report.
Growing Demand for LEDs a Positive Sign
The research can be a good news keeping in mind the growing developments on electric vehicles. LEDs have largely remained the candle lights in homes and offices for long-term cost savings. However, these have not found a core niche applications, which is crucial for their growth. The development of electric vehicle promise to provide this application. Electric vehicles rely on LED use during nights to capture a clear-image. However, the technology remains expensive. The new study promises a potential opportunity for an application which may witness tremendous growth in the near future.
