Problems solved by technology

However, both the final product and its preparation method have shortcomings. First, the phase structure of the donor material poly(3-hexylthiophene) and the acceptor material fullerene that constitutes the active layer of the final product is not ideal. , the two are only blended at the molecular level, which is not conducive to the formation of effective charge transport channels and exciton separation interfaces, resulting in low energy conversion efficiency of solar cells; secondly, the preparation method cannot obtain solar cells with higher energy conversion efficiency

Abstract

The invention discloses a carbon-based solar cell photosensitive film and a preparation method thereof. The film consists of a hole transport layer and a photosensitive active layer consisting of a donor and a receptor covered on a transparent conducting substrate in sequence, wherein the donor is a fiber stack layer which is 80-800 nanometers in fiber diameter and consists of a polythiophene derivative or a polystyrene derivative or a mixture of both; the receptor is a fullerene derivative or a carbon nanotube or perylene which is filled among the fibers of the donor. The method comprises the following steps of coating the hole transport layer on the transparent conducting substrate; preparing the polythiophene derivatives or the polystyrene derivative or the mixture of both and solvent into a spinning solution; electrostatically spinning the spinning solution on the transparent conducting substrate coated with the hole transport layer to obtain a fiber stack layer donor; coating a receptor solution prepared from the fullerene derivative or the carbon nanotube or the perylene and solvent on the fiber stack layer donor in an inert atmosphere; and drying in vacuum for at least one hour to obtain a target product. The carbon-based solar cell photosensitive film is applied widely to solar cells.
