Preparation method of fibrous solar cells having metal grid electrode, and the fibrous solar cells thereby

摘要

PURPOSE: A method for manufacturing a fibrous solar cell including a metal wire and the fibrous solar cell manufactured by the same are provided to obtain high energy conversion efficiency by forming the metal wire on a flexible substrate in comparison with a fibrous solar cell without the metal wire. CONSTITUTION: A large solar cell including a metal wire is manufactured on a flexible substrate. The manufactured large solar cell is cut with a fiber type. The flexible substrate is a polymer flexible substrate or a metal flexible substrate. The metal flexible substrate is made of one or more among Cu, Ni, Al, Fe, Cr, and stainless steel. The solar cell is cut by a slitting process or a laser process.
