Lumartix unveils solar simulator with plasma-light engine

Switerzland-based Lumartix has developed a steady-state solar simulator system for research labs. It claims a light emitter lifetime of more than 20,000 hours.

Mesoporous carbon for a 20-year stable perovskite solar cell

Scientists in Japan and Europe investigated the long-term stability of perovskite solar cells utilizing layers of mesoporous carbon, building on previous work demonstrating the strong potential of this approach. This latest work demonstrates a light-soaking effect, which allowed them to fabricate cells that retained 92% of their initial performance after 3,000 hours in damp heat conditions – which the researchers say is equivalent to 20 years in the field.


Perovskites meet the stability standard

European research group Solliance says its perovskite modules have passed three key industry standard reliability tests: Light soaking, damp heat and thermal cycling. The group said it is the first time perovskite modules of that size have achieved such results and represents a milestone in the technology’s move toward commercialization.
