Concrete facades could quickly capture solar power to energy buildings, employing a prototype photovoltaic cladding created by supplies enterprise LafargeHolcim and electronics manufacturer Heliatek.
The item combines LafargeHolcim’s concrete with a top rated layer of Heliatek’s HeliaFilm — a versatile solar film that is just one particular millimetre thick.
The providers not too long ago tested the hybrid item in a pilot project at the LafargeHolcim Investigation Center in Lyon, and they strategy to take it to market place in 2019.
According to LafargeHolcim, it has the possible to double the power generation that a creating can accomplished by conventional roof-primarily based photovoltaics, since facades take up a higher surface region.
“A ten-storey industrial creating covered with 60 % of its facade with the Ductal/HeliaFilm cladding method could create around 30 % of its annual power requirement,” stated LafargeHolcim, which very first unveiled the prototype final year.
“Our HeliaFilm is the active element which transforms creating cladding into a energy station,” added Heliatek CEO Thibaud Le Séguillon. “This is the path to green, localised electrical energy.”

Weighing significantly less than 5 per cent of a conventional solar panel, HeliaFilm is produced to be integrated into building supplies by creating element companies. Beyond LafargeHolcim’s concrete cladding, it could be employed with steel or glass.
Heliatek also make a connected item named HeliaSol, a stand-alone stick-on solar film that can be employed on current buildings. It comes in a variety of colours, such as a transparent choice.
The providers have created 40 square metres of Ductal/Heliatek facade to date, such as 25 square metres as aspect of the very first pilot project in September. A additional 200 square metres will be constructed as an installation in early 2019.
The providers are not the only ones attempting to redesign the solar panel so it blends in with its surrounding architecture. Two years ago, Tesla began generating the Solar Roof, solar panels disguised like common roof tiles.
A second current photovoltaic concrete project came from the Block Investigation Group at the university ETH Zurich, which installed thin solar cells on the exterior layer of concrete on a sinuous prototype roof.
