Cu(In,Ga)Se2 (CIGS) absorbers with several Ga/III, Ga/(In + Ga), profiles were fabricated by the so-called “multi layer precursor method” under the control of Ga flux rate during film's deposition. Open-circuit voltage (VOC) of CIGS solar cell is principally dependent on average band-gap...

In the present work we consider the growth of a very dilute concentration of anisotropic particles, nucleated with random orientations, in a matrix of growing spherical particles. It is assumed that the matrix particles obey the usual JMAK kinetics. We concentrate on describing the change in...

In the conventional Avrami–Kolmogorov–Johnson–Mehl model, the reaction or phase transition occurring in the 2D or 3D infinite medium is considered to start and proceed around randomly distributed and/or appearing nucleation centers. The radius of the regions transformed is assumed to...
