Scientists boost stability and efficiency of next-gen solar tech

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.

Pressure suppresses carrier trapping in 2D halide perovskite

(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.

Understanding the love-hate relationship of halide perovskites with the sun

(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.

Record efficiency for printed solar cells

(Swansea University) A new study reports the highest efficiency ever recorded for full roll-to-roll printed perovskite solar cells. It marks a key step towards cheaper and more efficient ways of generating solar energy.

New materials of perovskite challenge the chemical intuition

(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.

Vapor fix lifts up perovskite crystal performance

(King Abdullah University of Science & Technology (KAUST)) A facile and mild bromine treatment eliminates surface and bulk defects from perovskites to boost the materials’ optoelectronic properties.

Precision spray coating could enable solar cells with better performance and stability

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.
