This report studies the influence of alkali elements (Na, K) to morphological, structural
and optoelectronic properties of CIGS ceramic tile solar cell. Several ceramic enamels
with altered chemical composition in terms of amount of alkali elements have been
tested and compared. The influences of alkali type, its quantity and transfer mechanism
have been investigated. The solar cell device has been assembled and characterized.
The achieved results indicate that alkali elements (Na and K combination) modified the
surface roughness and its diffusion from the enamel toward the absorber affect to the
structural and final optoelectronic properties of the device. The alkali doping improve
the Ga incorporation in the crystal lattice and an increasing in open circuit voltage (Voc)
values, fill factor (FF) and the device efficiency. Optimal alkali quantities have been
also determined. The best conversion efficiency is achieved for the cell with 4% wt
Na2O and 3.2 % wt K2O (Eff. = 3,5 %), which presents an improvement of 30 % in efficiency relative to the standard (STD) solar cell sample chosen for comparative
purposes. [-]
