Photovoltaic electricity generation is a rapidly growing industry, and a key pillar of a decarbonised energy system. 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.
