Electricity generation using quantum dots in glass

Fluff? Where are the &#x27;current per square meter&#x27; stats? They claim &#x27;half your electricity from windows&#x27; but where&#x27;s the data?<p>My windows are not in direct sunlight most of the day and all of the night. Most are never - on the north side, east side, west side.<p>All of them are never optimally directed at the sun even when fully illuminated.<p>The opportunity to generate power from accidental&#x2F;incidental sources is very limited. Its always better to plan a real power installation with all the factors considered. 10x to 100x better.

Are windows in some part of the world optimally oriented towards solar radiation? Most residential windows in the US are shaded by awnings or face completely away from the path of the sun. It seems like only multi-story glass-clad buildings would be moderately relevant for this technology, and refacing, say, the Salesforce tower seems like it would be prohibitively expensive to make sense from an roi perspective.

So many near sighted comments.<p>Many buildings have little space for solar panels. Most building need to reglaze every thirty years. Many building have no optimally oriented glass.<p>This does not mean that PV Glass is worthless. If efficiency and cost work out then there may we’ll be a place for PV glass.

What about stability and longevity, since the first breakthrough 10 years ago various teams were struggling to make them work in solar cells as quantum dots are chemically unstable under oxidizing conditions and undergo photo corrosion reactions?

It all boils down to: what is the energy return on energy invested .

Not my field of natural science but I saw a very bright future for this a decade ago.<p>Quite promising equations.

What if it costs more electricity to produce this glass than it will ever produce in its entire lifespan? Does it make sense to produce the glass if that&#x27;s the case?
