Simulation of GaSe buffer layer on the CuInGaSe2-based solar cells by SCAPs

In this work, we simulate by SCAPs simulator (Solar Cell Capacitance Simulator) the Selenide Gallium buffer layer on the p-CuInGaSe2 based solar cells. The thicknesses reduction of the buffer layer was studied. The lattice parameters of the buffer and the absorber layers are almost similar. This can permit to the structure to be good and to be stable. This characteristic gives diminution of the in...
