Solar Power Generation Buildingoxin
A research team from Flinders University has investigated the development of smart windows and recently produced windows with the ability to generate electricity using sunlight.
To this end, a PhD student named Mark Twenty has developed a new solar cell using carbon nanotubes.
Unlike silicon-based samples, carbon nanotubes are inexpensive and capable of producing more energy efficiently. Twenty Says: Solar Power is One of the Most Expensive Renewable Energy Sources
The silicon solar cells used today are very expensive and require a lot of energy to purify them.
The efficiency of silicon solar cells is about 10%, which if it works, would take 15 years to offset the energy spent on producing them because fossil fuels are used to produce them.
“Carbon nanotubes are transparent, meaning they can be sprayed directly on the glass of windows without blocking sunlight,” says Mark Twenty. In addition, carbon nanotubes are flexible, so they can be added to various materials such as fabrics. Such technology is very appealing to those active in advertising.
Twenty says: Although the amount of energy produced by this solar window does not meet all the energy required for an office, it has significant financial and environmental benefits. Wherever there is a window, this cover will be usable; since the window and glass installation costs the same, with or without the cover, so it is economical to use.
Using this system is like painting the windows, while this painting produces electricity, since most office buildings lack the space to install solar panels, these windows are very useful.
This technology is very similar to the process of photosynthesis, in which plants produce energy from sunlight. However, the technology uses carbon nanotubes to generate electricity. When light shines through this solar cell, electrons are produced inside the nanotubes and cause electronic devices to function. So far, the system has produced a laboratory sample that will then have to be produced on an industrial scale. If all is done on schedule, one can expect the technology to hit the market in the next 10 years.
