…a new world record of 33.9% cell-level efficiency for a silicon-perovskite tandem cell, which is the first ever cell to surpass the Shockley-Queisser (S-Q) theoretical efficiency limit. Hence in this…
…plants, industrial gas production, electric arc furnaces, aluminium, chlor-alkali, polymers, paper, silicon, sulphur, glass, hydrofluoric acid, small-scale hydrogen and hydrogen cyanide. A best to worst ranking depends on the technical…
…improve? For example, today’s graphite anodes only intercalate 1 lithium ion for every 6 graphite atoms, which weigh 12 g/mol, yielding a charge density of 372 mAh/gram. Silicon anodes weigh…
A new solar cell is vying to re-shape the PV industry, with 2-5% efficiency gains and c25-35% lower silicon use than today’s PERC cells. This 12-page note reviews TOPCon solar…
…copper in the front contacts of solar cells. It diffuses into the silicon, where it is an “efficiency killer”. And it cannot readily be screen-printed. These issues are spelled out…
…takes 120-seconds, via a 100bpm slurry rate carrying 2.7ppg of sand. PropX has undertaken successful trials placing the sand containers on a vibration table, with a sloped discharge cone, silicon-inserts…
…trackers in 2023, mostly single-axis horizontal systems. It is a rare part of the solar supply chain, that is not dominated by Chinese suppliers – unlike PV silicon, or PV…
…to the Siemens Process, used to make 92% of the world’s PV silicon in 2021. Energy intensity is middling. Electricity comprises 30% of the total marginal cost, and c45% of…
