Boron-emitter development for TOPCon c-Si solar cells based on plasma-deposited boron diffusion source and poly-Si(n) passivating contact

Thibault Schaller, Ludovica Lunghi, Christophe Ballif, Franz-Josef Haug, Julien Hurni, Ezgi Genç

The n-type TOPCon technology is currently the leading approach in the industry. Generally, it involves two high-temperature steps that can result in long cycle times and expensive processes. In this context, we propose a lean manufacturing process based on ...

A halted photodeposition technique controls co-catalyst loading and morphology on organic semiconductor nanoparticles for solar H 2 production

Kevin Sivula, Victor Carle Adrien Boureau, Colin Jeanguenat, Connor Robert Firth

Solar hydrogen production with semiconductor photocatalyst particles typically requires co-catalysts to accelerate the hydrogen evolution reaction, but since co-catalysts are often deposited in situ, the rate of their nucleation/growth and role in parasiti ...
