We carried out KF postdeposition treatment (PDT) on a Cu(In,Ga)Se2 (CIGS) layer with a process time varying from 50 to 200 s. The highest CIGS solar-cell efficiency was achieved at a KF PDT process time of 50 s; in this condition, we observed the hig

Work function tuning has a significant influence on the performance of semiconductor devices, owing to the formation of potential barriers at the interface between metal-semiconductor junctions. In this work, we introduce a technique for tuning the w

Chemical bath deposition (CBD)-ZnS is used as a buffer layer for Cu(In,Ga)Se2 (CIGS) solar cell and then, plasma damage originated from the negative oxygen ions or neutral particles with high energy is regarded as an important issue during subsequent

Cu(In,Ga)Se2 (CIGS) solar cells were fabricated by varying the film thickness of the cracker-ZnS (c-ZnS) buffer layer from 0 nm to 20 nm, and performance was found to depend on c-ZnS film thickness. The best cell efficiency of approximately 8% was ob

We fabricated Cu(In,Ga)Se2 (CIGS) solar cells with three types of Zn(O,S) buffer layer produced by different techniques: S thermal cracking, chemical bath deposition (CBD), and reactive sputtering. The highest cell efficiency was obtained from the CI

Thin-film multijunction solar cells are considered to be the most promising structure for next-generation photovoltaic devices. We fabricated CuGaSe2 (CGS)/Cu(In,Ga)Se2 (CIGS) monolithic tandem solar cells. The intermediate AZO film was used as a rec

We propose a method to fabricate two-dimensional (2D) molybdenum disulfide (MoS2) layers to overcome issues in typical fabrication processes by promoting the sulfurization reaction of molybdenum (Mo). A thin sputtered-Mo layer was sulfurized using a

The photoluminescence (PL) of Cu(In,Ga)Se 2 solar cell with sputtered Zn(O,S) buffer layers annealed at various temperatures were measured. As the annealing temperature increased, the peak positions of PL spectra shifted to higher energies. The broad
