What caught the eye of internet readers this past week or so? Here on CleanTechnica, a certain reflecting pool led the list. Otherwise, well, it’s a little more of a normal list. Scroll down below and see what intrigues you. Reflecting Pool Becomes No-Go Zone As Algae Biofuel Mystery Deepens … [continued]
The smarter E Europe 2026 happened this week in Munich, with the lead event of InterSolar Europe co-located with ess Europe, Power2Drive and EM-Power. Regardless of the intended organization of the conference and exhibitions, the lines between them have increasingly blurred, as solar is combined with storage, EV charging and … [continued]
Oxford PV and the Fraunhofer Institute for Solar Energy Systems ISE have combined two high-efficiency technologies in a single photovoltaic module. To achieve this, they used perovskite-silicon solar cells from Oxford PV and connected them using the Matrix Shingle technology developed by Fraunhofer ISE. Oxford PV is a pioneer in … [continued]

The Fraunhofer Institute for Solar Energy Systems (ISE) is no stranger to solar power records, and it’s just set another one. Via its own III-V germanium solar PV module, the institute reached 34.4 percent solar module efficiency. The solar record march goes on. “The solar cells were developed by AZUR … [continued]
With the addition of on-site solar cell fabrication, the US branch of Qcells has achieved full, vertical, Made-in-the-USA status for its solar factory in Cartersville, Georgia (cropped, courtesy of Qcells).
Qcells has just begun manufacturing solar cells at its new factory in Cartersville, Georgia, the company announced today. It already produces solar modules there. The company won’t be producing only solar cells and modules at the factory, though. It is going to be a vertically integrated production facility for solar … [continued]
Elon Musk says that he wants SpaceX and Tesla teams to work together to build 100 gigawatts of solar power manufacturing capacity in the US — cells and modules. And he wants to do that within three years. There’s a lot to consider here. Before we get into some of … [continued]
