Silicon solar cells were supposed to be running out of headroom, yet a new device has pushed their performance to 27.81% efficiency and reset expectations for what a single-junction cell can do. That ...

A cluster of recent laboratory advances in ultra-thin solar cells suggests that lightweight, flexible photovoltaic devices may be able to move beyond niche prototypes if researchers can solve ...

As the price of silicon panels has continued to come down, we’ve reached the point where they’re a small and shrinking cost of building a solar farm. That means that it might be worth spending more to ...

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at ...

In the second PV development, announced simultaneously, a new III-V silicon PV module has achieved an efficiency of 31.3 percent, setting a record in its class, and is based on established, ...

The use of solar cells, devices that can convert sunlight into electricity, has grown exponentially over the past decades.

Fraunhofer scientists have announced two efficiency records for III-V tandem modules. The team says its 34.2% efficiency III-V germanium PV module is the most efficient solar module in the world, ...

Researchers have developed a perovskite-organic tandem solar cell that achieves 26.4 percent efficiency. Unlike rigid silicon modules, the lightweight design can generate power on curved or flexible ...

A 833vsquarevcentimetre tandem module with an efficiency of 34.2 percent was built by a second research team from Fraunhofer ISE as part of the 'Vorfahrt' project. It consists of triple III-V ...

An international research group has published breakthrough findings demonstrating how the ionic compound caesium bromide (CsBr) can significantly improve the efficiency of crystalline silicon (c-Si) ...
