Latest Patents

Fujiwara's patent titled "Method for manufacturing CIS based thin film solar cell device" outlines a sophisticated approach to improve the quality of solar cells. Before the buffer layer deposition step (denoted as P), a pre-rinse step (Pis) is introduced to eliminate any unwanted deposits on the surface of the CIS-based light absorbing layer (D). This enhancement aids in minimizing the adverse effects that may disrupt the formation reaction of the buffer layer, thereby improving its coverage and transparency. Additionally, a further rinse step is implemented following step P, allowing for thorough cleaning and removal of colloidal solid matter that might compromise the buffer layer's high resistivity. Remarkably, the rinse solution from a secondary rinse tank is re-used, showcasing an environmentally-conscious aspect of the technology. Furthermore, after completing step P, a draining and drying step (P) is incorporated, followed by the deposition of an n-type window layer, which consists of a transparent conductive film.
