【明報專訊】太陽能光伏板的關鍵物料多年來一直都以矽（硅）、尤其是單晶矽（單晶硅）的光電效應轉化率最高。可是，經過多年發展，單晶矽的潛力已差不多發掘殆盡，陷於停滯不前；而在近期，串聯式光伏板及多種嶄新物 Read more: https://news.mingpao.com/pns/%e7%b6%93%e6%bf%9f/article/20220621/s00004/1655748627382/%e5%a4%aa%e9%99%bd%e8%83%bd%e6%8a%80%e8%a1%93%e7%aa%81%e7%a0%b4-%e5%a2%9e%e8%bd%89%e5%8c%96%e7%8e%87%e6%93%b4%e5%a4%a7%e6%87%89%e7%94%a8
EVEN THOUGH solar panels have improved over the years they are still not very efficient at doing their job. Standard panels using silicon-based solar cells typically convert 17-19% of the sun’s energy into electricity. Read more: https://econ.st/2FK6lvI
Robert Sauchelli doesn’t have a solar panel, but he’s all for the idea — before he retired, he devoted 21 years to energy efficiency work at the Environmental Protection Agency. To show his support, Sauchelli has been paying an extra… Continue Reading →
