Abstract
A method of forming thin film solar cell includes the following steps. A substrate is provided, and a plurality of first electrodes are formed on the substrate. A printing process is performed to print a light-absorbing material on the substrate and the first electrodes to form a plurality of light-absorbing patterns. Each of the light-absorbing patterns corresponds to two adjacent first electrodes, partially covers the two adjacent first electrodes, and partially exposes the two adjacent first electrodes. A plurality of second electrodes are formed on the light-absorbing patterns.

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.
