Photovoltaic OLEDs: The Lightbulb Combines with the Solar Panel


Organic LEDs take electricity and buy viagra discount convert it directly into light, a wonderful and useful purpose that we have great hopes for.  But what if the process could run both ways.  Sometimes the OLED turns electricity into light, and other times it turns light into electricity.  It's basically the same thing, just backwards, right?

Well, apparently, it is possible, as scientists and engineers at Cornell have done it!  These have all the wonderful properties of OLED's, they're flexible, they produce a lot of light per watt, and they can be mass produced inexpensively.  But also, when exposed to bright light, the reaction is reversed, and a current flows out of the OLED instead of into it.

So now, OLEDs can be both an energy collector and a light emitter, depending on the needs of the consumer.  Imagine your cell phone's backlight collecting energy from ambient light when not in use.  Or your windows collecting energy during the order chinese viagra day and then producing light at night. 

Soon, OLEDs may offer both low-cost lighting and low-cost energy production.  A paper on this subject was just published in the journal Science, in which the Cornell researchers recognized that they needed to discover ways to make the photovoltaic reaction more efficient before it can be mass produced.

Organic LED's are already amazing

When I worked in Product Planning at Saturn (GM), some suppliers did a presentation on OLED's and how they were brigbter, less directionally sensitive for viewing, and less sensitive to cold temperatures. If it becomes a means to generate energy, these would be the ultimate technology.

I wonder if OLEDs that generate could produce energy from light if the whole display isn't being used. That would be even more amazing.

I'm interested to find out how to manufacture OLEDs even in laboratory . What is necessary for such a process?
