Summary: This study investigated the cause of potential-induced degradation (PID) in Cu(In,Ga)(Se,S)(2) (CIGS) thin-film solar cells. It was found that PID occurs due to changes in the bulk doping concentration and built-in potential at the junction. The study also distinguished the effects of temperature and voltage, showing that PID phenomena occurred when potential difference was involved.

Summary: Thin-film modules are becoming popular in the photovoltaic market due to their competitive cost compared to traditional crystalline silicon modules. Among them, CuIn(1-x)GaxSe2 (CIGS) cells are leading the expansion in the market due to their low temperature coefficient and ability to absorb UV and IR radiation. Comparative studies among different photovoltaic technologies, including theoretical comparisons, simulations, and experimental tests, show that CIGS performance is approaching that of silicon cells.

Summary: Solar cells with the ZnO/CdS/Cu2ZnSnSe4/Mo/glass structure were studied using photoluminescence (PL) before and after irradiation with high energy electrons. The PL spectra showed dominant bands from different layers, and irradiation led to a decrease in intensity without affecting the band tails. The red shift rate of the dominant band increased after irradiation, suggesting the formation of deep non-radiative traps.

Summary: This study investigated the influence of Ar background pressure on the properties of Mo back contact on polyimide films. High Ar pressure caused crack formation in the Mo layer and decreased fill factor, while reducing the Ar pressure improved the fill factor. Additionally, the stress condition of Mo also affected the thermal diffusion of alkali metal.

Summary: By using in-situ X-ray diffraction technique, the effect of pre-annealing on Cu-In-Ga electroplated and sputtered thin films, which are precursor materials for Cu(In,Ga)(S,Se)(2) based solar cells, was studied in a custom-made furnace. The results showed that the shelf time at room temperature significantly affected the metallic phases in the precursors, unlike sputtered precursors. Above the decomposition temperature of Cu11In9 (310℃) and below around 520℃, mainly Cu-9(In,Ga)4 phase remained in all precursors. These findings have implications for high quality CIGS manufacturing.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
