Since 1993 it has been recognized that for solar cells based on the chalcogenide absorber
material Cu (In, Ga) Se 2 (CIGSe) the incorporation of Na is crucial to obtain the highest …

Organic and inorganic materials such as perovskites, copper indium gallium diselenide,
cadmium telluride, and copper zinc tin sulfide/selenide (CZTS/Se) have been employed to …

Cu2ZnSn (S1–x Se x) 4 (CZTSSe) alloys are promising candidates for low-cost and high-
efficiency thin-film solar cells. Compared to CdTe and Cu (In x Ga1–x) Se2, CZTSSe uses …

In this work we present a method to grow Sb 2 Se 3 thin films with a potential use as
absorber layers in solar cell structures. The films were grown on several substrates: soda …

The temperature dependence of electrical conductivity of the Cu 2 ZnSnS 4 (CZTS) thin films
has been measured in order to identify the dominant conduction mechanism. These CZTS …

With high absorption coefficient (10 4 cm− 1), optimal bandgap (~ 1.5 eV), low toxicity and
the abundance of its constituent elements, kesterite (Cu 2 ZnSnS 4 or CZTS) displays the …

Direct solution coating technique has emerged as a promising economically viable process
for earth abundant chalcogenide absorber materials for photovoltaic applications. Here …

Bimetallic oxide materials with amorphous state usually exhibit singular peculiarities due to
their periodic disorder structure, implying great potential applications as high-performance …

Abstract Al/p-Si/Cu 2 CoSnS 4/Al quaternary functional semiconductor photodetectors
showing solar detector properties were produced via sol-gel method. SEM, EDS and XRD …

Sol–gel methods were used to fabricate Al/p-Si/Cu 2 NiSnS 4/Al quaternary functional solar
detectors. Diffraction, spectroscopy and microscopy were used for the structural …
