Patent ID: 8361826

Claim:
A method of manufacturing a thin film solar cell, comprising: preparing a substrate on which unit cells are defined; forming transparent conductive layers on the substrate and corresponding to the unit cells, respectively, the transparent conductive layers spaced apart from each other with a first separation line therebetween; forming light-absorbing layers on the transparent conductive layers and corresponding to the unit cells, respectively, the light-absorbing layers spaced apart from each other with a second separation line therebetween; forming a third separation line by removing a portion of the light-absorbing layers in each unit cell, the third separation line spaced apart from the second separation line; disposing a silk screen over the light-absorbing layers having the second and third separation lines such that the silk screen corresponds to the third separation line; after forming the third separation line and disposing the silk screen corresponding to the third separation line, forming a reflection material layer by applying a conductive paste to substantially an entire surface of the substrate excluding the silk screen; and forming reflection electrodes corresponding to the unit cells, respectively, by sintering the reflection material layer.
