IMPROVING THE PERFORMANCE OF SOLAR CELLS BASED ON THIN FILM ELECTROGENERATED OF CuInSe2
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 12
Abstract
This study shows that thin films of CuInSe2 and CuIn(Se,S)2 may be developed by the electrochemical method of deposition using an electrolyte solution containing sulphate. The films obtained are almost amorphous and heat treatment selenizing or sulfurizing is always necessary to improve the crystallinity of the films and to confer the physical properties to them for their application in photovoltaic devices. The heat treatment in the presence of H2S also allows the preparation of thin films of the quaternary CuIn(Se,S)2. The analysis by X-ray diffraction shows that the films are well crystallized. The current-voltage characteristic of the cell CuIn(Se,S)2 shows an efficiency of 6.37%.
