Micro or nano fiber producing method for e.g. photovoltaic cell, involves hot stretching deformable film adhered on porous matrix, under effect of fluid which escapes of matrix at pressure higher than pressure exerted on free face of film

摘要

The method involves hot stretching a thin deformable film (4) adhered on a porous matrix (1), under the effect of a fluid which escapes of the matrix at a pressure higher than the pressure exerted on a free face of the film. The matric has a face, opposite to the face utilized for hot stretching the film, sealed by a continuous layer for obstructing the passage of the fluid. An independent claim is also included for a device for implementing a method for fabricating a micro or nano fiber.
