Sergio Giraldo,Edgardo Saucedo,Markus Neuschitzer,Florian Oliva,Marcel Placidi,Xavier Alcobé,Victor Izquierdo-Roca,Shinho Kim,Hitoshi Tampo,Hajime Shibata,Alejandro Pérez-Rodríguez,Alejandro Pérez-Rodríguez,Paul Pistor,Paul Pistor +13 more
TL;DR: In this article, a detailed analysis of the phase evolution with and without Ge was performed to demonstrate how the presence of Ge influences the preferred reaction scheme during the selenization of kesterite solar cells.
Improvement of voltage deficit of Ge-incorporated kesterite solar cell with 12.3% conversion efficiency
TL;DR: In this article, the authors demonstrate the improved efficiency of a Cu2Zn(Sn1− x Ge x )Se4 (CZTGSe) thin-film solar cell with a conversion efficiency of 12.3%.

Akihiro Nakane,Hitoshi Tampo,Masato Tamakoshi,Shohei Fujimoto,Kang Min Kim,Shinho Kim,Hajime Shibata,Shigeru Niki,Hiroyuki Fujiwara +8 more
TL;DR: In this article, the authors developed a general analysis scheme in which the optical and recombination losses in submicron-textured solar cells are evaluated systematically from external quantum efficiency (EQE) spectra.

Ge-incorporated Cu2ZnSnSe4 thin-film solar cells with efficiency greater than 10%
TL;DR: Ge-incorporated Cu2ZnSnSe4 (CZTGSe) thin films were prepared using a two-step process comprising co-evaporation of each element and a subsequent annealing step as discussed by the authors.

Improvement of minority carrier lifetime and conversion efficiency by Na incorporation in Cu2ZnSnSe4 solar cells
TL;DR: In this paper, the effect of Na incorporation in CZnSnSe4 (CZTSe) solar cells was investigated via photoluminescence (PL) and time-resolved PL (TRPL) measurements as well as photovoltaic properties.
