Hybrid Perovskites based Highly-efficient Polymer Tandem Photovoltaics

Professor Zakhidov Anvar A.

Project target

In order to reach the project aim we will concentrate on the following targets:

- Development of theoretical concept and experimental principals of obtaining optically-transparent conductive carbon nano-tubes based layers as well as production of prototypes of carbon nano-tubes for optically-transparent conductive layers.

- Development of theoretical concept of obtaining tandem elements based on organic/metallic perovskites (MAPbICl) as intermediate photo-active layer and polymer solar cells with translucent electrodes based on aerogel of carbon nano-tubes.

- Development of physico-mathematical models of tandem elements based on organic/metallic perovskites (MAPbICl) and polymer solar cells with consequential and parallel architecture.

- Obtaining coating films based on metalorganic perovskites (MAPbI3) with defined ion crystalline structure. They will be controlled by one of the following methods: two-atomizing spraying МAI and PbI2 in controlled atmosphere, consequential film coating by PbI2 immersion into МAI solution, one-stage coating with preliminary prepared PbI2 and МАI mix solution or consequential separate layers coating of смеси  PbI2 and МАI, MAI vapor-phase deposition on pre-formed surface-supported PbI2 film.

- Development of obtaining methods of flexible conductive films based on modified carbon nano-materials. We assume it will be based on the methods of controlled local coagulation and lamination of carbon nano-tubes in the process of spraying modifiers with medium level of charge carriers mobility  such as 2,8- difluoro -5,11-bis(triètilsililètinil) antraditiofen (TES-ADT) и 6,13- bis (triizopropilsililètinil) pentacene (TIPS- pentacene);

Development of highly effective device for transformation of various sunlight spectral bands will include the use of technology of metalorganic perovskites (MAPbI3) integration into cascade (tandem) structure with the use of organic films, coated with electrodes with carbon nano-tubes with high mobility charge carriers. For the purpose of the technology realization we will undertake comparative analysis of parallel and consecutive component network in tandem.

- Creation of tandem photoelectric devices with FTO-p-i-n-CNT-n-i-p-ITO architecture is planned on the basis of hybrid metalorganic perovskites and polymers. Their high efficiency will be achieved by the use of elastic electrodes on the basis doped nanotubes layers combined by lamination.

- Another method which significantly increases the efficiency of photoelectric transformer is ion shutter. Preliminary research results proved it agrees with photoactive perovskite layer. To overcome main difficulties of organic photoelectric transformers, we plan to achieve long length of diffusion path of charge carriers not only in perovskites, but also in crystalline transportation layers.

Project objectives

The aim of the project is development of theoretical concept and experimental principals of tandem elements based on organic/inorganic hybrid perovskites and polymer solar cells, which provide for wider solar spectrum to be transformed into electric power.

Uniqueness project

Presently development of hybrid organic/inorganic perovskites based solar elements is the one of most promising areas. Their use provided for unijunction element efficiency up to 18%.Thus the target of the projects becomes of high scientific and practical importance.

Development of new types of efficient and cheap solar panels which can replace the existing silicon ones, is one of the most advanced fields of renewable power generation in the world. The creation of such materials will minimize the dependence of mankind on organic fuel and provide for environment-friendly development.
