• Solar cells can be made with tin instead of lead, Warwick scientists find
• Breakthrough to make solar power cheaper and more commercially viable
• Solar power could be used in mobile phones, laptops and cars

[/font][font size=3]…

Solar cells based on a class of semiconductors known as lead perovskites are rapidly emerging as an efficient way to convert sunlight directly into electricity. However, the reliance on lead is a serious barrier to commercialisation, due to the well-known toxicity of lead.

Dr Ross Hatton and colleagues show that perovskites using tin in place of lead are much more stable than previously thought, and so could prove to be a viable alternative to lead perovskites for solar cells.

Lead-free cells could render solar power cheaper, safer and more commercially attractive - leading to it becoming a more prevalent source of energy in everyday life.

The team have also shown how the device structure can be greatly simplified without compromising performance, which offers the important advantage of reduced fabrication cost.

1. I am holding out a bit longer

Until it becomes less expensive and better technology

2. BUT.....

Will big oil and power companies allow it?? If they can control it and it's profits, yes... Nevada and Florida are in the process of trying to control solar recently... grrrrrrrrr.....

3. You know what? I dont care if they do control it and profit from it.

I’d rather have them produce solar power than oil, coal and gas.

If your objection is that you want all solar power to be produced on roofs, I’m sorry, but, there aren’t enough suitable roofs in this country to supply our electricity needs.

[font face=Serif][font size=5]NREL Raises Rooftop Photovoltaic Technical Potential Estimate[/font]

[font size=4]New analysis nearly doubles previous estimates and shows U.S. building rooftops could generate close to 40 percent of national electricity sales[/font]

March 24, 2016

[font size=3]Analysts at the Energy Department's National Renewable Energy Laboratory (NREL) have used detailed light detection and ranging (LiDAR) data for 128 cities nationwide, along with improved data analysis methods and simulation tools, to update its estimate of total U.S. technical potential for rooftop photovoltaic (PV) systems. The analysis reveals a technical potential of 1,118 gigawatts (GW) of capacity and 1,432 terawatt-hours (TWh) of annual energy generation, equivalent to 39 percent of the nation's electricity sales.

Now, that’s just 39% of our electricity. What happens when we start trying to shift other energy use? (Electric cars, electrically heated buildings…)


If your objection is to the “big oil and power companies” manufacturing solar panels… well… which large corporation do you want to do it? because the mom-and-pop machine shop down on the corner isn’t going to.

4. do you feel better now??

you seemed a little hot..
