1. Introduction. Research of thin film solar cells based on p-type compound semiconductor absorber layers has mainly focused on Cu(In,Ga)(S/Se) 2 (CIGS) and CdTe. Recently, Cu 2 ZnSn(S/Se) 4 (CZTS) has also been considered as a possible candidate for photovoltaic applications since it only consists of abundant elements.
However, potentially other p-type semiconductors with Cited by: These thin films can consist of crystalline, protocrystalline, or amorphous silicon. In addition, II-VI polycrystalline compounds like CdTe or ternary compounds like CuIn(Ga)Se2(S)-alloys are being investigated and developed.

Uwe Rau, Hans-Werner Schock, in McEvoy's Handbook of Photovoltaics (Third Edition), Defect physics of Cu(In,Ga)Se 2. The defect structure of the ternary compounds CuInSe 2, CuGaSe 2, CuInS 2, and their alloys, is of special importance because of the large number of possible intrinsic defects and the role of deep recombination centers for the performance of the solar cells.
Thin film solar cells based on the ternary compound Cu2SnS3. History and current status of Cu-ternary-based photovoltaic devices are reviewed. Heterojunction and homojunction research on CuInS2, CuInSe2 and CuInTe2 is covered. Some emphasis is placed on the CdS, Cd(Zn)S/CuInSe2 thin-film solar cell, which has reached a 10% solar-conversion efficiency and has demonstrated remarkable stability characteristics.
Cu 2 ZnSn(S,Se) 4 thin films and solar cells are successfully fabricated by sulfurization of the precursors evaporated from the Cu 2 ZnSnSe 4 compound. In this study, a new crystallization process of fabrication of the Cu 2 ZnSn(S,Se) 4 thin film by the difference in substrate temperature at the time of preparation of the precursor is confirmed.
Following the introduction on energy demands and history of solar cells, different generations of solar cells are described along with their working principle.
After the discussion on ternary compounds for thin film solar cells, currently considered quaternary compounds I 2-II-IV-VI 4 for absorbers in thin film solar cells are described. Thin ﬁlm solar cells based on the ternary compound Cu 2SnS 3 Dominik M.

The power conversion efficiency of polymer solar cells (PSCs) has undergone rapid development in recent years, and a ternary strategy further powers the development of PSCs. The research team led by Professor Fujun Zhang at Beijing Jiaotong University has focused its research on ternary. 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). For ternary compounds grown by atomic layer deposition (ALD), some compositional variations during the first nanometers of deposition can occur if the initial cycles of the process differ from film-on-film growth.
This is problematic for applications that require a precise control of the composition near the interface to the underlying material. One such application is thin-film solar cells.

For ternary compounds grown by atomic layer deposition (ALD), some compositional variation during the first nanometers of deposition can occur if the initial cycles of the process differ from film-on-film growth.
This is problematic for applications that require a precise control of the composition near the interface to the underlying material. One such application is thin-film solar cells. The ternary compound CuGaS 2 as a member of the chalcopyrite family has a bandgap energy (Eg) of around eV and has been considered as a promising material for high efficiency tandem solar cells.

material is necessary for the high performance of solar cells. When Zn is diffused in CdS, a ternary compound CdZnS is formed. Since CdZnS has a larger band gap than CdS therefore thin films of CdZnS can lead to a decrease in window absorption losses and has resulted in short circuit current in solar cells .
