Progress in Polycrystalline Thin-Film Cu(In,Ga)Se2 Solar Cells

open access: yesInternational Journal of Photoenergy, 2010
For some time, the chalcopyrite semiconductor CuInSe2 and its alloy with Ga and/or S [Cu(InGa)Se2 or Cu(InGa)(Se,S)2], commonly referred as CIGS, have been leading thin-film material candidates for incorporation in high-efficiency photovoltaic devices ...

Investigation of Structural, Optical and Photovoltaic Properties of Sb2S3 Thin Films

open access: yesCumhuriyet Science Journal, 2017
Sb2S3 thin films wereprepared on amorphous glass substrates by chemical bath deposition (CBD) atroom temperature. The Sb2S3thin films were characterized by x-ray diffraction (XRD), Raman spectroscopy,scanning electron microscopy (SEM) and UV-Vis ...

High-Efficiency Precipitate Recycling Strategy Paves the Way for Efficient Sb<sub>2</sub>S<sub>3</sub> Solar Cells Fabricated by CBD Method. [PDF]

open access: yesAdv Sci (Weinh)
A novel PR strategy was proposed to improve CBD‐derived Sb2S3 film quality. It synergistically optimized the CBO of CdS/Sb2S3 interface and the back‐contact barrier, while the VS2 donor defect was converted into SSb2 acceptor defect with lower concentration.

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Study of Cu(In,Al)Se2 thin films prepared by selenisation of sputtered metallic precursors for application in solar cells [PDF]

open access: yes
Cu-In, Cu-Al and Cu-In-Al metallic precursor layers were deposited using radio-frequency magnetron sputtering and selenised to produce thin films of CuInSe2 (CIS), CuAlSe2 (CAS) and CuIn1-xAlxSe2 (CIAS), respectively.

Ridge aperture antenna array as a high efficiency coupler for photovoltaic applications [PDF]

open access: yes, 2011
Weak absorption of light near the absorption band edge of a photovoltaic material is one limiting factor on the efficiency of photovoltaics. This is particularly true for silicon thin-film solar cells because of the short optical path lengths and limited
