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 fabricated Cu(In,Ga)Se2 (CIGS) solar cells with a chemical bath deposition (CBD)-ZnS buffer layer grown with varying ammonia concentrations in aqueous solution. The solar cell performance was degraded with increasing ammonia concentration, due to

We fabricated Cu(In,Ga)Se2 (CIGS) solar cells with chemical-bath deposited (CBD) ZnS buffer layers with different deposition times. The conversion efficiency and the fill factor of the CIGS solar cells reveal a strong dependence on the deposition tim

The effect of electron blocking layer (EBL) on the injection and radiative efficiencies in InGaN/GaN multiple quantum well (MQW) light-emitting diodes (LEDs) was investigated. In order to identify the dominant mechanism, we measured the external quan

We analyzed the current-crowding process and its effects on carrier spill-over and light outputpower loss in InGaN/GaN blue-light-emitting diodes. When the current density was measured to be 3.1 times larger, the carrier spill-over was observed to be

The switching of resistance between two discrete values, known as random telegraph noise (RTN), was observed in individual single-walled carbon nanotubes (SWNTs) and C60-filled SWNTs (the so-called peapods). The RTN has been studied as a function of
