"enables commercialization, scalable... resource-abundant, low-cost, eco-friendly... overcomes low efficiency/ high current losses due to electron-hole recombination, inhibiting Sn loss/ better low temperature mixing/ allowing faster/ lager crystal grow... performance varies significantly depending on where doping occurs... improved absorber layer density/ crystallinity/ energy band structure, fewer defects, smoother charge transport in the solar cell"
