    Let us consider the basic physical processes taking place in a semiconductor solar cell with a heterojunction (Fig. 1).The device is composed by two semiconductors with different band gap values [1, 6].The wider-band material forms so-called window layer (for which the corresponding characteristics in Fig. 1 have the subscript “W”) and is used to process high-energy photons, Author: P.P. Horley, L. Licea Jiménez, S.A. Pérez García, J. Álvarez Quintana, Yu.V. Vorobiev, R. Ramír. Despite the high efficiency of III-V solar cells based on gallium arsenide, their usage in large-scale terrestrial application is very limited due to the excessive cost of GaAs and Ge wafers. Herein, we have developed high-quality epitaxial semiconductor thin films on inexpensive flexible metal tapes to overcome the wafer cost as well as benefit from the lower manufacturing cost of Author: Devendra Khatiwada, Monika Rathi, Pavel Dutta, Sicong Sun, Carlos A Favela, Yao Yao, Yongkuan Li, Sa.

    Spectral upconversion has the potential to compensate for sub-bandgap transparency of single-junction solar cells. Here a composite module of GaAs solar cells is presented that can improve their one-Sun photovoltaic performance by capturing long-wavelength photons below the bandgap via plasmonically enhanced spectral upconversion.

Gallium arsenide thin film. The semiconductor material Gallium arsenide (GaAs) is also used for single-crystalline thin film solar cells. Although GaAs cells are very expensive, they hold the world's record in efficiency for a single-junction solar cell at %.

A thin-film solar cell is a second generation solar cell that is made by depositing one or more thin layers, or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic or metal.

Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous thin-film silicon (a-Si, TF-Si).

and Yeh, Y.C.M.}, abstractNote = {The present research is directed toward demonstrating the feasibility of producing high-efficiency GaAs solar cells with high power-to-weight ratio by organo-metallic chemical vapor deposition (OM-CVD) growth of thin epi-layers.

Thin film copper indium gallium selenide (CIGS) solar cells have exceeded 20% efficiency in and are almost at the same level as polycrystalline solar cells now.

The ability to combine the Cu(In,Ga)(S,Se) 2 materials family internally as well as with other materials to form multijunctions leaves the pathway open to further efficiency.

The feasibility of producing high-efficiency (15% or greater) thin-film gallium arsenide (GaAs) solar cells with costs suitable for terrestrial power generation was demonstrated by growing thin epi-GaAs films on suitably prepared low-cost substrates to replace the expensive single-crystal GaAs wafers used conventionally.

Nanostructures have been widely used in solar cells due to their extraordinary optical properties. In most nanostructured cells, high short circuit current has been obtained due to enhanced light absorption. However, most of them suffer from lowered open circuit voltage and fill factor.

Abstract Epitaxial lift-off is used to create thin-film III-V solar cells without sacrificing the GaAs wafer. It is based on selective etching of an AlAs release layer between the wafer and the cell structure using an HF solution.
