（HPへ） by Bing, Image Creator The result of the trial on �@ChatGPT、GPT-4, �AGoogle, Gemini, �BMicrosoft、Bing, １．Information is collected from the World, and it is not biased towards infomation centered on Japananese companies, so we can support Japanese companies on the premise of world information. ２．You can easily get a wealth of materials, so if you use multiple AIs, you can prevent more bias. ３．Bing and Gemini will suggest various things you want to investigate, such as, "what you want to investigate further". This is important, and if you repeat it, you can check the subject of the survey 360 degrees. ChatGPT, you have to make your own questions. At the moment, Bing, which can be tried freely for free, is convenient. The content of the trial is about perovskite, invented in Japan, which is thought to be an important industry in the future, and iodine, which can be produced in Japan abundantly, and is a necessary resourse for making perovskite. Perovskite can provide electricity for automobiles, household energy, and various equipment. I made it a trial because many people are interested in it, and the future direction is not clear. The question is,　”Which manufauturer has the highest power generation efficiency among perovskite solar cells ?" �@ChatGPT、GPT-4 As of the latest data, several companies and research labs have made siginificant strides in developing high-efficiency perovskite solar cells. Some of the leading entities in this field include Oxford Photovoltaics, a spin-out from the University of Oxford , which has been at the forefront of achieving high-efficiency perovskite solar cells. However, this is a rapidly evolving field with frequent updates in efficiency records. For the most current and specific information, I recommend checking the latest publications, industry reports, or announcements from notable conferences in the renewable energy sector, as advancements and record can change quickly . �AGoogle, Gemini A challenge in Pinpointing a Single manufacturer Determining the manufacturer with the highest power generation efficiency in perovskite solar cells is complex for a few reasons. 1.Rapid Technological Advancement: The perovskite solar cell field is rapidly evolving, with efficiency records being broken frequently. 2.Focus on Research and Development Many of the highest efficiency cells are produced in research labs rather than commercial manufacturing facilities. 3.Different Efficiency Metrics: Efficiency can be measured in various ways (e.g., lab-scale vs. module-level, single-junction vs. tandem) making direct comparisons difficult.　（Silicon solar cells have the feature of absorbing long wavelengths of light, and perovskite can abosorb short wavelengths of light） Leading Contenders While it's challenging to pinpoint a single manufacturer with the absolute highest efficiency, some companies and research institutions are at the forefront of perovskite solar cell development: LONGI Green Energy Technology: This Chinese company has set world records for tandem perovskite-silicon solar cells. Panasonic:In collaboration with Japan's NEDO, Panasonic achieved a high efficiency for a large-area perovskite solar module. Research Institutions: Universities and national laboratories often lead in perovskite research, with institutions like the National University of Singapore and the National Renewable Energy (NREL) achieving impressible results. Important Considerations When evaluating perovskite solar cell efficiency, It's crucial to consider: Cell Size:Efficiency can vary significantly between small lab-scale cells and larger commercial modules. Cell Type: Tandem cells, which combine perovskite with silicon, often achieve higher efficiencies than single-junction perovskite cells. Certification: Efficiency claims should be verified by independent testing organizations like NREL To get the most accurate and up-to-date information, I recommend checking recent new articles and research papers from reputable sources. "Would you like to focus on a specific aspect of perovskite solar cells, such as tandem cells, commercialization, or specific geographic regions?" (Question by Gemini) �BMicrosoft、Bing, As of 2023,Panasonic holds the record for the highest power generation efficiency among perovskite solar cells. They achieved an energy conversion efficiency of 18.1% with an 804cm2 perovskite solar cell. This efficiency is notable for a practical-sized module, making Panasonic a leader in this innovating field. "Are you interested in the latest advancements in solar technology or considering solar solutions for your home or business ?
