The successful fabrication and measurement at room temperature of field-effect transistors from halide organic-inorganic hybrid perovskites was championed by researchers from both Wake Forest University and the University of Utah.
This family of crystalline materials is hailed as the key that will open a bastion of renewable energy resources for the whole world.
According to the research’s lead author and Wake Forest Physics assistant professor Oana Jurchescu, “the structure of the field-effect transistors was designed in such a way that electrostatic gating of materials can be realized to directly distinguish its underlying electrical properties.” He then added that the said transistors are then fabricated with the team of experts from the University of Utah which were subsequently measured at the Wake Forest Lab.
In a world where renewable energy is fast becoming a global trend because of its positive impact to the environment, the use of this family of crystalline materials to optimize efficiency of solar power technology holds great promise. Up until now, researchers around the globe have not perfected the fabrication of field effect transistors that can measure a material’s charge transport capabilities. According to Jureschu for solar cells to be efficiently formed, the need for robust optical absorption and efficient charge carrier transport must be present. This is where Wake Forest researchers’ first generation transistors come in. With these, they were able to directly quantify and calculate electrical properties paving the way for more accurate approximations.
This exciting breakthrough could pave the way for the next generation of solar cell technologies according to Jureschu navigate to this site. She further added that the cells, which are responsible for effectively converting solar energy into usable electrical energy, will usher to a more sustainable and eco-friendly source of energy that can be utilized at an affordable cost.
University of Utah top-notch Physics and Astronomy professor, Zeev “Valy” Vardeny also served as a co-author to the project. According to him this initiative has also ushered to a more optimized utilization of optoelectronics applications.
A detailed next-step study of the research development has been published by both teams in the MRS Communications online journal. A press release was also published along with the said research material. According to Jureschu, the hybrid perovskites was first introduced in 2009 and was highly regarded as the future of solar cells technology. After almost 6 years now, its ability to convert power efficiently has astoundingly grown from 4 percent to as much as 20 percent or more. This breakthrough breaks away from the sluggish performance of conventional materials in solar power generation technology.
Jureschu along with her understudy, graduate student Yaochuan “Josh” Mei, had worked as a team on this project. According to Mei this realization clearly emanates from years of hard work on researches pointed at the knowledge and infrastructure of organic electronics. The hybrid perovskites, according to Mei, is quite new to their research but they were able to gather considerable knowledge that could put more advantages to the future of solar power technology.
Jureschu further mentioned that a lot of their efforts will be focused on the lessons gained from its inception. They will definitely double their efforts in boosting its efficacy by looking at its reaction to other injected carriers and on electrical, optical and magnetic field applications.
