“…The Empa research group was able to modify the properties of the CIGS layer so that it can be grown at low temperature without compensating the light absorption of the CIGS layer which contributes to the photo-current in solar cells [11]. Since 2010 until 2016, ceramics have also been used as flexible substrate [75,84]. A submodule efficiency of 15.9% has been achieved by AIST in Japan using flexible zirconia-based ceramic sheet as a substrate [75].…”

“…A submodule efficiency of 15.9% has been achieved by AIST in Japan using flexible zirconia-based ceramic sheet as a substrate [75]. Ceramic substrate is able to withstand higher temperature than the soda-lime glass and polymers due to its higher chemical, mechanical, and thermal stability and low porosity [84,85]. However, its brittle behaviour might be an issue for industrial production on large scale ( Table 2).…”

Copper Indium Gallium Selenide- (CIGS-) based solar cells have become one of the most promising candidates among the thin film technologies for solar power generation. The current record efficiency of CIGS has reached 22.6% which is comparable to the crystalline silicon- (c-Si-) based solar cells. However, material properties and efficiency on small area devices are crucial aspects to be considered before manufacturing into large scale. The process for each layer of the CIGS solar cells, including the type of substrate used and deposition condition for the molybdenum back contact, will give a direct impact to the efficiency of the fabricated device. In this paper, brief introduction on the production, efficiency, etc. of a-Si, CdTe, and CIGS thin film solar cells and c-Si solar cells are first reviewed, followed by the recent progress of substrates. Different deposition techniques’ influence on the properties of molybdenum back contact for CIGS are discussed. Then, the formation and thickness influence factors of the interfacial MoSe2 layer are reviewed; its role in forming ohmic contact, possible detrimental effects, and characterization of the barrier layers are specified. Scale-up challenges/issues of CIGS module production are also presented to give an insight into commercializing CIGS solar cells.

“…However, not all of the foreign ions can match with the lattice sites, the foreign ions which doped in the interstitial sites cause defect states in the band gap [11,12]. The original coordinates of the UV-vis spectrum registered for HC is transformed to Kubelka-Munk function (KM) versus photon energy (hv) and then expressed by Tauc plot (Figure 3b) which shows the relation of (KM 3 hv) 2 5 f(hv) [10,13,14]. The value of the band gap is estimated by extrapolation of the linear part of the dependence.…”

In this work, preparation and characterization of Hangjin2# clay (HC) photocatalyst, a new type of low cost natural metal‐oxide based on clay mineral from Inner Mongolia of China, was presented. The photocatalytic activity of HC was evaluated through the photocatalytic water splitting and the photodegradation of wastewater pollutants in aqueous suspension. The effects of CH3OH, Na2S–Na2SO3, and triethanolamine (TEOA) on the effectiveness of photocatalytic water splitting were investigated, respectively, which indicated that HC in all sacrificial reagents system had better hydrogen production ability than P25‐TiO2. An enhanced photocatalytic degradation of methyl orange (MO) in the presence of HC was detected. Moreover, photocatalytic activity and catalyst stability were maintained after consecutive recycling cycles in water splitting and degradation of wastewater, respectively. The relationship between the photocatalytic properties, the structure, and the morphology of the HC was discussed. Results indicated that the light‐induced photocatalytic activity of HC was mainly attributed to the synergies between hierarchical structure and the distribution of foreign metal atoms in its crystal lattice. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1003–1010, 2018

“…On the other hand, according to the investigation in literature, it is known to us that the traditional manufacture of ceramic materials often requires massive amount of natural raw materials, such as clay and feldspar [8][9][10]. However, recently, taking into consideration the big challenges in environmental protection and energy saving, nontraditional raw materials are needed in the synthesis process of the ceramic materials.…”

For the purpose of energy saving in buildings, a foam ceramic insulation (FCI) was prepared by using fly ash (FA) and ceramic waste (CW) as the main raw materials for its matrix part and foam part, respectively. The effects of the sintering temperature and the additive agent on the macroscopic performances were systematically measured and investigated. The experiment results indicate that for the matrix sample 5% quartz addition makes the rupture modulus at 1200°C reach high to 34.28 MPa, while the corresponding water absorption capacity is only 0.83%. In addition, for the foam sample with 1 wt% silicon carbide, the lowest measured bulk density and thermal conductivity at 1200°C are 0.471 g/cm 3 and 0.1184 W/(m•K), respectively. Furthermore, the proposed simulation model predicts that the effective thermal conductivity of FCI decreases with the decrease of the bulk density. Moreover, the simulation results calculated by EnergyPlus software indicate that the synthetic FCI can efficiently reduce the building's heating and cooling loads and exerts excellent energy conservation effect.
