The truth about Graphene Perovskite solar PV panels
the truth
about perovskite solar panels
At Solŵr Wales, our engineers are increasingly being asked about a 'new' solar PV technology utilising a mineral called 'Perovskite', that promises to be lighter, cheaper and more efficient than traditional Silicon based solar panels.
Although terms like 'breakthrough' and 'revolutionary' are often used, this technology was initially developed in 2009 but, despite it's apparent advantages, Perovskite PV panels are still several years away from commercially viable manufacture.
BONUS: What is Perovskite?'Perovskites' are a family of materials, many of which have shown potential for high performance and low costs in the production of solar cells.
The Perovskites commonly used in photovoltaic (PV) solar panels are, more specifically, 'metal-halide perovskites', being made of a combination of organic ions, metals and halogens. As an aside; Perovskites in other applications may be made of oxygen in place of halogens, and are usually entirely inorganic.

perovskite
. . .in its natural, crystaline, form
While perovskite solar cells have become highly efficient in a very short time, perovskite PV is not yet manufactured at scale and a number of challenges must be addressed before perovskites can become a competitive commercial PV technology.

tandem panels
Perovskites can also be layered with a different absorber, such as silicon, in order to capture energy from a broader spectrum of light, resulting in a PV panel that can theoretically achieve greater efficiency than cells made of either material alone.
