Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Transparent solar windows for high rise buildings

RATE THIS! +28
Posted in Science on 1st Jun, 2015 06:36 PM by AlexMuller

Oxford PV is developing and commercialising thin-film perovskite solar cells, which can be printed directly onto silicon solar cells, CIGS solar cells or glass. This will drive a paradigm shift in the aesthetics, performance and cost of both current solar panels and Building Integrated Photovoltaic (BIPV) systems.

 
Perovskite materials have astounded the solar cell community with a steep rise in efficiency from 4% in 2010 to a certified efficiency of 20.1% (NREL) in 2014- already surpassing many other solar technologies.
 
To reach this remarkable efficiency in such a short time, many iterations of the cell architecture were trialled through to the current planar thin-film devices, more akin to other thin-film technologies.
 
Perovskite solar cells are already performing at 17% in the laboratory. We expect to see single-junction perovskite solar cells reach 25% cell efficiency within a few years. For a tandem perovskite/perovskite solar cell 30% is quite possible within the same timeline.
 
At 20% efficiency a 35 story office building with all semi-transparent Perovskite solar cells would get 60% of its power from the windows.

It is not going to take much longer that solar power is going to take over at some form of fossil fuel resources - this is my hope anyway Reply
