How do hybrid solar cells work?

Hybrid solar cells mix an organic material with a high electron transport material to form the photoactive layer. The two materials are assembled in a heterojunction -type photoactive layer, which can have greater power conversion efficiency than a single material. One of the materials acts as the photon absorber and exciton donor.

What is a hybrid solar cell?

Hybrid photovoltaics; Organic–inorganic heterojunctions; Organic–inorganic photovoltaics; Polymer–metal oxide solar cells A hybrid solar cell is a photovoltaic device relying on charge transfer at the interface between two semiconductors, one being organic and the other being inorganic.

What are the advantages of hybrid solar cells?

Hybrid solar cells combine advantages of both organic and inorganic semiconductors. Hybrid photovoltaics have organic materials that consist of conjugated polymers that absorb light as the donor and transport holes. Inorganic materials are used as the acceptor and electron transport.

Which materials are used in hybrid solar cell devices?

In hybrid solar cell devices, organic materials such as carbon nanotubes (CNTs), polymers, and fullerenes as well as inorganic materials like QDs, nanospheres, inorganic nanotubes, and silica are being explored with various compositions.

What are hybrid solar cells based on dye-sensitized solar cells?

Hybrid solar cells based on dye-sensitized solar cells are fabricated by dye-absorbed inorganic materials and organic materials. TiO 2 is the preferred inorganic material since this material is easy to synthesize and acts as a n-type semiconductor due to the donor-like oxygen vacancies.

Which inorganic materials are used in hybrid solar cells?

Many of the commonly used inorganic materials in hybrid solar cells such as TiO 2 and ZnO are high band gap materials, which absorb only light in the UV range. 22 Therefore, the organic materials are selected to absorb most light from the solar spectrum, in particular in the visible range.
