I found this article particularly interesting because my energy source was solar in the debate. Indeed, the cells are very expensive to make, and I think it is cool that they are trying to develop more cost efficient ways to make them. If we give the electrons a speedy way to cross over the materials, then we could also capture more energy, too. Though I understand the issue with the different types of light, I think that we should have developed this technology much before. The "bulk" photovoltaic effects in visible light make it easy to use these solar panels, and I think that it would be good to continue on this path of investigation. The most amazing thing for me was how they were thinking of staking solar cells to catch the most valuable photons. One thing I didn't understand was when they said Raman spectroscopy. I found out that it is a technique used to find low-frequency modes in a system such as vibrational and rotational. The result is the energy of the photons being shifted up or down. Ever since the debate, it had been my personal opinion that solar would be the most efficient if it didn't cost so much. Thankfully, they are coming up with new technology. In conclusion, I support the scientists in their new experiment, and I hope that one day we will get cheaper, more efficient solar panels.
Like Angela, my energy source was also solar power. I think this new kind of solar power construction, the "perovskite crystal", is capable of doing wonders for the world's ways of obtaining energy! One of the major cons of solar that I found in the debate was that it was one of the most expensive sources. This could help that! However, there is one thing I am concerned about. When I researched solar, I found that it was already very abundant. Now, with even more energy being harvested, I wonder- Is there such a thing as too much energy? When I did a bit of short research, I found some different results. Some sources said that there may be too much, and others said it was a good thing. However, if anyone finds some more in-depth results, I am curious!
Overall, I think the scientists are clever in their thinking of this possibility. I hope for the experiment to continue and leave our world with something great!
Seeing as we have recently had our energy debate, it was interesting to hear about a recent improvement to one of the sources. If we did the energy debate again, I wonder whether this new information would impact the debate at all. Also, I find it interesting that a certain combination of materials makes an effect that directs electrons in a certain way.
I find this article on a new New Paradigm for Solar Cell Construction Demonstrated very interesting for several reasons. First these new solar cells are more efficient than the older cell designs. Since the cells are more efficient two things can happen. First you may be able to produce more power in the same area has the older cell. Secondly the new cells design may be able to be located in areas that were previously too small for the older larger solar cell arrays. Now, if you can have more power efficiency, you should be able to recover the cost of the solar array quicker than the if you had an older model solar array. Another big advantage of these cells they are made common “ inexpensive, non-toxic and earth-abundant elements.” ("perovskite crystal"). All this seems to add up to a product that should be cheaper to buy and produce more power than the older solar cell designs.
