In modern solar cells, laser technology is used to form localised structures such as a selective emitter through doping or to locally ablate dielectric layers for contact definition. A critical factor is the ability to passivate the laser-induced defects to prevent premature charge carrier recombination reducing the cell efficiency. Hydrogenation is such a passivation technique. The exact mechanisms have until recently been poorly understood, so this timely reference covers the recent breakthroughs in the understanding of hydrogen passivation.</p> <p xmlns="http://ns.editeur.org/onix/3.0/reference">The book addresses key technologies for improving the efficiency of solar cells, including the industry-dominating PERC concept with an added rear passivation layer to reduce recombination. Coverage includes hydrogen passivation mechanisms, bulk and surface defect passivation, hydrogenation of light-induced defects, potential negative impacts of hydrogen, and laser doping for rapid diffusion and for selective emitter formation. This work also provides brand new results that enable low-quality silicon to be used for heterojunction applications and could pave the way for future low-cost, high-efficiency silicon solar cell technologies featuring passivated contacts to be fabricated on p-type wafers.</p> <p xmlns="http://ns.editeur.org/onix/3.0/reference">This work is indispensable for researchers in the field of photovoltaic energy, in academia as well as industry.</p>Tue, 23 Mar 2021 09:35:33 GMThttps://shop.theiet.org:443/hydrogen-passivation-and-laser-doping-for-silicon-solar-cells
