US Patent No: 9117962

CIGS light-absorbing ink and method for preparing CIGS light-absorbing layer

---

Abstract

---

The present invention relates to a method for preparing a CIS- or CIGS-based light-absorbing layer which is included in a thin film solar cell. More particularly, the present invention relates to a method for preparing a CIS- or CIGS-based light-absorbing layer which ultimately improves the efficiency of a solar cell since the remaining carbon impurities in the formed light-absorbing layer are minimized and additional sulfurization treatment or selenium treatment is made optional, not requisite.
