Report
Throughout civilization, scientists have endeavored to find answers to the questions of the natural world. Their efforts have advanced science and technology to help create the modern world we live in. In this discussion, you will share a significant scientific development related to the topic of your news story and learn about many others from your peers.  Create one initial post and follow up with at least two response posts. For your initial post, address the following: 1. Identify a major development relevant to the topic of your news story and the scientist(s) involved. This could be an event, advancement, discovery, or paradigm shift. For example, if your topic is volcanoes, you could discuss the effect of NASA's Earth Observing System  Terra  satellite, which can detect eruptions in sparsely populated or inaccessible regions. This technological advancement has helped scientists study volcanoes even in areas they can't get to.  2. Provide a brief summary of the scientific development and the scientist(s) who contributed to it.  3. Briefly address how this development impacted what we know about your topic and how we study it. Use examples from your news story and from the sources you found that discuss the development. For your response posts, address the following: 1. How do you think the developments your peers chose influenced the world outside of the sciences? Why do these developments matter to us as individuals and a society?  Remember, this assignment is graded on the quality of your initial post and at least two response posts to your classmates. If you refer to any module resources, be sure to include an attribution (or citation) to the resource.  To complete this assignment, review the Discussion Rubric. A major development relevant to the topic of solar energy, is the technology is going to be “turbo-charged”, however they need to be redesigned, because of a shortage of materials. They need to change them in order to make them the size they will need to be to generate the amount of energy needed to be able to take over being our main source of energy. There has been a breakthrough in the efficiency of solar cells due to a new material called perovskite. The scientists that constructed the new cell was a research group that was led by Prof Steve Albrecht from Helmholtz-Zentrum Berlin, in Germany. They call the new discovery the tandem solar cell. The old silicone solar cells have a 29% max efficiency, and the new tandem solar cell has achieved a world record efficiency of 32.5%. This development has impacted what we know about solar energy and how we study it by sparking a new path of brainstorming the question of “How to create the most efficient solar cell with using different materials there are plentiful?”
The thought of using different and multiple materials on the solar cell is just the beginning of the innovations and advancements in solar technology that we will see. Kaunas University of Technology. (2023, August 22). Improvements in silicon-perovskite tandem cells that helped achieve a whopping 32.5 percent efficiency.   ScienceDaily .
