Improved Performance of CuInGaSe2 Solar Cells with Patterned Front Contact
In order to improve the efficiency of CIGS thin film solar cell
a novel AZO/patterned Ag/AZO multilayer front contact was investigated. In this architecture
middle Ag thin film is patterned
which has the identical shape and size with the metal grid of solar cell and under the metal grid. This architecture can increase the electrical properties when the transmittance is constant. The transmittance and sheet resistance of new architecture were compared with that of traditional front contact. In comparison with the solar cell with AZO and AZO/Ag/AZO front contact
the CIGS solar cell with new architecture shows the higher short circuit current and improves efficiency from 13.83% to 14.53%. The noval architecture can improve the efficiency of CIGS solar cell.
