Patent ID: 8476100

Claim:
A method of forming a thin film solar cell, comprising: providing a substrate; forming a plurality of first electrodes on the substrate, wherein the step of forming the first electrodes comprises: forming a transparent conductive layer on the substrate; and patterning the transparent conductive layer to form the first electrodes; performing a printing process to print a light-absorbing material on the substrate and the first electrodes to form a plurality of light-absorbing patterns, wherein each of the light-absorbing patterns corresponds to two adjacent first electrodes respectively, partially covers the two adjacent first electrodes, and partially exposes the two adjacent first electrodes; and forming a plurality of second electrodes on the light-absorbing patterns, wherein the step of forming the second electrodes comprises: forming another transparent conductive layer and a non-transparent conductive layer on the light-absorbing patterns and the first electrodes exposed by the light-absorbing patterns; and patterning the non-transparent conductive layer and the another transparent conductive layer to form the second electrodes.
