SINTERED CZTS NANOPARTICLE SOLAR CELLS

摘要

The present invention discloses an absorber composition and photovoltaic device (PV)using the composition comprising nanoparticles and/or sintered nanoparticles comprising compounds having the formula MA X MB yMC z (LA aLB b)4 where MA, MB and MC comprise elements chosen from the group consisting of Fe, Co, Ni, Cu, Zn, Cd, Sn and Pb, LA and LB are chalcogens and x is between 1.5 and 2.2, y and z are independently the same or different and are between.5 and 1.5 and (a+b)=1. Particularly preferred synthetic routes to uniform thin films in PV devices comprising sintered nanoparticles of Cu2ZnSnSe4 and Cu2ZnSnS4 are disclosed.
