Conductive Polymer Solar Cells via Multilayer Film Structure with Graphene and Polyaromatic CarbonAdvanced solar cells are becoming more popular as the price of electricity continues to drop. One important technology for lowering costs is using polymer-based solar cells instead of silicon cells. In this study, a conductive polymer film was created by combining graphene and polyaromatic carbon (PAC) films. The result was a multilayer structure that exhibited excellent electrical properties in sunlight. The advantages of this type of cell include high efficiency, low cost, light weight, flexibility and adaptability to various applications such as flexible displays or batteries. This research provides another method for creating efficient polymer-based solar cells that could be used in future generations of devices.

Some applications for multilayer structures made with a covalent organic framework (COF) film in contact with a polyaromatic carbon (PAC) film include solar cells, flexible displays, lighting devices, RFID tags, sensors, photoreceptors, batteries, capacitors and gas-storage devices. The PAC film can be for example a single layer graphene film. In these multilayer structures the precursor compounds are combined in the presence of the PAC film to create the desired structure.

What are some key features of the invention?

• Multilayer structures

• COF film

• PAC film

• Precursor compounds

What are some similar inventions on the market?

There are a few similar products on the market that use multilayer film structures. These include solar cells, flexible displays, lighting devices, RFID tags, sensors and photoreceptors.

How could this be used?

Many potential applications for multilayer structures made of covalent organic frameworks (COF) in contact with polyaromatic carbon films exist. For example, these structures can be used in solar cells and flexible displays, among others. The COF film allows for an efficient transfer of light while the PAC film provides a stable platform upon which other materials may be deposited. This opens up many possibilities for using this technology in devices that are currently unavailable due to stability issues related to traditional substrates like silicon.

What are some things to look out for with this?

One risk to using a COF film in contact with PAC film is the possibility of an electrical short-circuit. Another potential risk is that the two films will not adhere well to one another, resulting in interfacial defects and decreased performance.

What are the overall impressions of this invention?

The product is well designed and has a good overall feel to it.

Final comment expressed in a poem (written by an A.I.)

A COF film and a PAC film in contact,
Make a multilayer structure that is quite compact.
With applications like solar cells and RFID tags,
This combination just might be the next big fad!
