HJT solar: Indium summer?
…material. But the numbers on pages 11-12 show that HJT solar designs repay these costs about 10-100x over. Will Indium be a bottleneck for HJT solar? The rise of HJT…
HJT solar: Indium summer?
HJT solar modules are accelerating, as they are highly efficient, and easier to manufacture. But HJT could also be a kingmaker for Indium metal, which is used in transparent and…
Electromagnetic energy: Planck, Shockley-Queisser, power beaming?
…solar (HJT) and this year about the push towards perovskite tandems in solar patents from LONGi. It feels like the ultimate goal will be multi-junction cells that capture along the…
Indium producers: companies and market outlook?
…HJT solar cells and digital devices. 60% of global supply is produced by 20 Chinese companies. But five listed materials companies in Europe, Canada, Japan and Korea also stand out….
New energies: the age of materials?
…using 20-30% less silver in solar modules, but new HJT cells are actually using 80-100% more silver, because this helps to deliver efficiency gains that deflate all of the other…
LONGi: technology review and solar innovations?
…in our screen of solar module manufacturers. LONGi aims to continue driving efficiency gains through the solar industry, especially via HJT cells and perovskite tandem cells. In November-2023, LONGi set…
Silver pastes for solar contacts?
…increasingly also the back too (in TOPCon and HJT cells), forming the electrical contacts with the underlying silicon substrate. Can any companies have an edge? We reviewed 15 patents from…
Solar insolation: by latitude, season, date, time and tilt?
…location). And of the insolation that does reach a solar module, only c20-25% is currently converted into useful electricity, in todays best HJT modules. Calculating the insolation ultimately available for…
