“…4 (a) [26][27]. The lower intense peaks at binding energies 930.7 and 950.3 eV are close to that of Cu 2 S but we couldn't obtain this compound peaks from the XRD results, while the dominant peaks at the binding energies of 929.7 and 949.5 eV did not match those of any ternary compound according to the XPS database [25].…”

Low-cost thin film modules based on copper antimony tin sulphide (CATS) were introduced for solar harvesting to compete for the already developed compound semiconductors. In this study, CATS thin films were deposited on soda lime glass using thermal evaporation technique followed by a rapid thermal annealing in an argon atmosphere. X-ray diffraction analysis revealed that the annealed samples were poly-crystalline and their crystallinity was improved with increasing annealing temperature. The constituent elements and their corresponding chemical states were identified using X-ray photoelectron spectroscopy. The obtained optical band gap for CATS thin film was found 1.58±0.06 eV which is nearly equal the optimal band gap value of CIGS and CdTe and GaAs -one of the highly efficient thin film material for solar cell technology. Furthermore, the good optical absorbance and low transmittance of the annealed CATS thin films in the visible region of light spectrum assured the suitability of the CATS thin films for solar cell applications.

“…A noticeable decrease in carrier mobility was also observed in the crystallized IZTO film deposited at 200 o C because grain boundary formation in the crystalline films formed an additional scattering barrier for electrons. 12 Therefore, the electrical resistivity increases drastically with increasing substrate temperature at 200 o C.…”

This study examined In-Zn-Sn-O (IZTO) films deposited on glass substrates by pulsed DC magnetron sputtering with various substrate temperatures. The structural, electrical, optical properties were analyzed. Xray diffraction showed that the IZTO films prepared at temperatures > 150 o C were crystalline which adversely affected the electrical properties. Amorphous IZTO films prepared at 100 o C showed the best properties, such as a low resistivity, high transmittance, figure of merit, and high work function of 4.07 × 10 −4 Ω, 85%, 10.57 × 10 −3 Ω −1 , and 5.37 eV, respectively. This suggests that amorphous IZTO films deposited at relatively low substrate temperatures (100 o C) are suitable for electrode applications, such as OLEDs as a substitute for conventional crystallized ITO films.

“…[4][5][6] In many respects the basic underpinning materials physics can be reasonably well set out. [7][8][9][10] Thus, the high conductivity of the prototypical transparent conducting oxide (TCO) SnO 2 -doped In 2 O 3 (ITO) derives from the presence of shallow donor or impurity states located close to the conduction band of the host (In 2 O 3 ), the donor states produced via chemical substitution of Sn 4 + for In 3 + or by the presence of oxygen vacancy impurities states [7] in In 2 O 3Àx (Figure 2). At room temperature the proximity of such impurity states to the host conduction band ensures facile thermal ionization into the band, developing, ultimately, a degenerate, itinerant electron gas of current-currying electrons which also gives rise to far-infrared (Drude-like) absorption and high electrical conductivity, but at the same time the fundamental host bandgap is left intact, that is, the electrically conductive material remains optically transparent in the visible region.…”

The critical topic of energy and the environment has rarely had such a high profile, nor have the associated materials challenges been more exciting. The subject of functional materials for sustainable energy technologies is demanding and recognized as a top priority in providing many of the key underpinning technological solutions for a sustainable energy future. Energy generation, consumption, storage, and supply security will continue to be major drivers for this subject. There exists, in particular, an urgent need for new functional materials for next‐generation energy conversion and storage systems. Many limitations on the performances and costs of these systems are mainly due to the materials′ intrinsic performance. We highlight four areas of activity where functional materials are already a significant element of world‐wide research efforts. These four areas are transparent conducting oxides, solar energy materials for converting solar radiation into electricity and chemical fuels, materials for thermoelectric energy conversion, and hydrogen storage materials. We outline recent advances in the development of these classes of energy materials, major factors limiting their intrinsic functional performance, and potential ways to overcome these limitations.
