James and I had lunch the other day with Simon Wardley.
During the course of what turned out to be a wide-ranging discussion Simon brought up the topic of flexible solar panels. I was delighted to read today then that Xtreme Energetics and HP are teaming up to produce
a solar energy system designed to generate electricity at twice the efficiency and half the cost of traditional solar panels
According to the piece, XP will use thin-film, transparent transistors developed by HP which are made from readily available materials such as Zinc and Tin – which have the added advantage of not having environmental issues.
Within 24 months, the company will release roof panels integrated with HP’s technology to deliver dramatic energy gains at a comparable price point to conventional PV systems, Colin Williams, CEO of Xtreme Energetics said. “Our panels will be twice as efficient, we’ll be able to deliver a higher energy density, and customers will have the option of choosing a color.”
The fact that the electronics are transparent means that more light gets through and thus the efficiency is further improved.
If these are truly transparent, south-facing windows on buildings could have these applied without significant impact on light entering the building. Ten at times when most energy is needed (sunny days when the aircon is turned up to 11), these transparent PV walls are cranking out the power to cool the building.
It is cheaper peak shaving – I like it.
