Photon enhanced thermionic emission could double efficiency of solar cells Engineers at Stanford have developed a process which can harness the light and heat of the sun simultaneously, which could lead to solar cells that are twice as efficient as those currently available. Called photon enhanced thermionic emission — or PETE for short — the process differs from traditional cells which lose efficiency as temperatures rise, and the materials needed to build the cells are cheap and widely available. The engineers got around the lower efficiencies by coating a piece of semiconducting material with a thin layer of the metal cesium, which enables the material to use both heat and light simultaneously. While the materials as currently demonstrated work best in very high temperatures, the researchers indicate that in the near future, the materials could have wide enough application to make them competitive with traditional forms of energy. * www.nature.com * www.wipo.int In this video I’m showing the progress that I made with my solar heater. Now I need to collect more bottles, so I went to the local supermarket and they will help me to collect the bottles that I need. Cutting and taping the bottles will take some time, but after that I can focus on the next task, and that will be insulating the copper pipe with all the fittings. I will show you how I’m going to do that. So stay tuned, and thumbs up if you like it 🙂 Also visit this youtube channel from jcanivan, he shows a …
