A new efficient perovskite solar cell plus low cost, high volume manufacturing spells more bad news for the natural gas industry
Researchers have created next-generation solar modules with high efficiency and good stability. Made using a type of material called perovskites, these solar modules can maintain a high performance for over 2000 hours. Their findings have brightened prospects of commercialization.
(Center for High Pressure Science & Technology Advanced Research) Here, we show a remarkable PL enhancement by 12 folds using pressure to modulate the structure of a recently developed 2D perovskite (HA)2(GA)Pb2I7 (HA = n?hexylammonium, GA = guanidinium). This structure features an extremely large cage previously unattainable, affording us a rare opportunity to understand the structure?property relationship and explore emergent phenomena in halide perovskites.
(Eindhoven University of Technology) Perovskiet solar cells are at the center of much recent solar research. The material is cheap and almost as efficient as silicon. However, perovskite cells have a love-hate-relationship with the sun. The light they need to generate electricity, also impairs the quality of the cells, limiting efficiency and stability over time. Research at the Eindhoven University of Technology and universities in China and the US now sheds new light on the causes of this degradation.
Solar energy researchers are shining their scientific spotlight on materials with a crystal structure discovered nearly two centuries ago.
(Oregon State University) Solar energy researchers are shining their scientific spotlight on materials with a crystal structure discovered nearly two centuries ago.
(Institute of Physics, Chinese Academy of Sciences) Materials scientists have synthesized a new type of perovskite–one of the most common crystal structures of materials deployed for a range of uses, from superconductors to photovoltaics–that goes against conventional thinking about how such structures behave at extreme pressures such as those that exist deep in the Earth.
Although perovskites are a promising alternative to the silicon used to make most of today’s solar cells, new manufacturing processes are needed to make them practical for commercial production. To help fill this gap, researchers have developed a new precision spray-coating method that enables more complex perovskite solar cell designs and could be scaled up for mass production.
