Negar Naghavi,Daniel Abou-Ras,N. Allsop,Nicolas Barreau,S. Bucheler,Ahmed Ennaoui,Ch.-H. Fischer,C. Guillén,Dimitrios Hariskos,J. Herrero,Reiner Klenk,Katsumi Kushiya,Daniel Lincot,Richard Menner,Tokio Nakada,Charlotte Platzer-Björkman,S. Spiering,Ayodhya N. Tiwari,Tobias Törndahl +18 more
TL;DR: In this paper, a review on the recent work concerning Cd-free buffer and window layers in chalcopyrite solar cells using various deposition techniques as well as their adaptation to chal copyrite-type absorbers such as Cu(In,Ga)Se-2, CuInS2, or Cu(in,Ga)(S,Se)(2).
Journal ArticleDOI
18% Efficiency Cd-Free Cu(In, Ga)Se2 Thin-Film Solar Cells Fabricated Using Chemical Bath Deposition (CBD)-ZnS Buffer Layers
Tokio Nakada,Masayuki Mizutani +1 more
TL;DR: In this paper, a Cadmium-free high efficiency Cu(In, Ga)Se2 (CIGS) thin-film solar cells have been fabricated using chemical bath deposition (CBD)-ZnS buffer layers.
Journal ArticleDOI
Novel device structure for Cu(In,Ga)Se2 thin film solar cells using transparent conducting oxide back and front contacts
TL;DR: In this paper, the performance of CIGS-based thin-film solar cells with transparent conducting oxide (TCO) front and back contacts was investigated and shown to be almost the same as those with metallic Mo back contacts when the deposition temperatures were below 500°C for SnO 2 :F and 520 ǫ c for ITO.
Journal ArticleDOI
High-efficiency Cu(In,Ga)Se2 thin-film solar cells with a CBD-ZnS buffer layer
TL;DR: In this paper, high-efficiency Cadmium-free Cu(In,Ga)Se2 (CIGS) thin-film solar cells have been fabricated using a chemical bath deposition (CBD)-ZnS buffer layer, a wider band gap material than of conventional CBD-CdS.
Journal ArticleDOI
Effects of Sodium on Cu(In, Ga)Se2-Based Thin Films and Solar Cells
TL;DR: In this article, a new type of solar cell with a ZnO:Al/buffer/ p-Cu(In, Ga)3Se5 heterojunction structure is suggested.
