Building Integrated Photovoltaics

Written By Nick Hodge

Posted August 20, 2007

At both Wealth Daily and Green Chip, we’ve been touting the benefits of solar power for quite some time–and our readers have taken handsome profits in the process.

But, just as in other industries, the solar sector is evolving. 

It started with bulky, rigid panels that had to be installed after a building’s construction.  These are the photovoltaic systems most people think of whenever solar is mentioned.


For all you scientists, these first generation solar cells are either monocrystalline or polycrystalline–the latter is what we normally see on roofs today.

After those cumbersome cells came the second generation, thin film models.  The most successful of this generation has been the cadmium telluride (CdTe) series of cells.

These cells are much thinner, use less material, and are easier to produce–but they’re still rigid. 

And the main company that produces these cells has been the darling of Wall Street for the past nine months, soaring from $23.50 last November to around $85.21, where it hovers today. (Before the recent correction, it got has high as $123.21.)

That’s a 262% gain for the lucky green investors got in on this thing’s IPO.

The Best is Yet to Come

But those gains could be minor compared to what’s currently taking place in this industry. 

Back in May, I wrote an article for Energy and Capital about thin film organic solar.  In that article I talked about being able to spray solar cells on nearly any surface using nanotechnology.

While we may not be there just yet–at least on a commercial scale–we’re getting closer.

Using CIS (Copper-Indium-Diselenid) technology, a few companies are now making thin film solar cells that are flexible.  So instead of casting silicon into blocks and cutting them into wafers, thin solar cells can be printed on sheets and rolled off on film with much less waste–much like how a newspaper is printed.

Companies are using this technology to make products that can be integrated right into the products used for building construction.  These are called building integrated photovoltaics (BIPV).

This technology can be used to make solar roofing tiles and architectural photovoltaic glass–very cool stuff.  Solar panels can be incorporated right into a building’s façade or roof, and my even add some aesthetic appeal.

Jeff just released the name of one company that is making these products to his Green Chip Stocks subscribers.  And if this thing performs just half as well as Jeff’s recent recommendations, you could be sitting on some pretty fat gains.

But you have to hurry, this stock is already moving north.

If you want to get in on the action, I suggest you get your name on the Green Chip Stocks list, ASAP. 

Until next time,
