Abstract

A film solar cell comprises top and bottom transparent baseboards. It is prepared by arranging conduction electrode and catalyst layer in interval on one transparent conduction film of substrate as well as arranging conduction electrode and nanomutihole semiconductor material block in interval on another one, soaking dyestuff in said nanomaterial, overlapping two transparent baseboards and sealing periphery of them to form cavity with electrolyte. The internal parallel electrode is also prepared for obtaining output current of solar cell.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to a large-area internal parallel dye-sensitized nano-film solar cell and a manufacturing method thereof. technical background [0002] In 1991, the laboratory of Professor M.Grtzel of the Institute of Technology in Lausanne, Switzerland reported a new dye-sensitized nano-thin film solar cell on Nature (O'Regan, B.; Grtzel.M, 1991, 353, 737). The research results immediately received widespread international attention and attention. Since 1991, it has been an international research hotspot. Its low cost and production cost, easy industrial production technology, and broad application prospects have attracted many scientists and enterprises to invest. [0003] Dye-sensitized nano-thin-film solar cells use organic photosensitive functional molecules combined with semiconductor nanomaterials to photoelectrically convert solar energy. It combines the functions and characteristics of organ...
