“…These semiconductor heterojunctions increase the performance of SBFCs because of the reduced electrodes/electrolyte interfaces polarization and because the heterojunction space charge region with BIEF can accelerate ion transport and avoid short circuit (Zhu et al, 2016b;Zhu et al, 2017;Xia et al, 2019). The DLFC was reported using an anode and a cathode analogous to the conventional SOFC (Zhu et al, 2011c) to construct SBFCs as shown in Figure 4A, which is similar to the configuration of the planar p-n heterojunction solar cells (Oikawa et al, 2015;Wu et al, 2015). Hence, we can call this anode/cathode twolayer device a planar p-n heterojunction device because the anode is n-type and the cathode is p-type.…”

“…To summarize, from the semiconductor aspect, the fuel cell may be represented as a semiconductor p-i-n three-layer device using respective n-type anode, intrinsic type electrolyte (no or very less electronic conduction compared with the ionic one), and p-type cathode, as shown in Figure 2B. This type of device is very similar to the one in solar cell devices (Liu and Kelly, 2014;Oikawa et al, 2015;Wu et al, 2015). Furthermore, if the middle electrolyte layer (i-type) is removed, a p-n two-component/layer device, i.e., DLFC, naturally appears, which is a p-n heterojunction device (Figure 2C).…”

Fuel cells are highly efficient and green power sources. The typical membrane electrode assembly is necessary for common electrochemical devices. Recent research and development in solid oxide fuel cells have opened up many new opportunities based on the semiconductor or its heterostructure materials. Semiconductor-based fuel cells (SBFCs) realize the fuel cell functionality in a much more straightforward way. This work aims to discuss new strategies and scientific principles of SBFCs by reviewing various novel junction types/interfaces, i.e., bulk and planar p-n junction, Schottky junction, and n-i type interface contact. New designing methodologies of SBFCs from energy band/alignment and built-in electric field (BIEF), which block the internal electronic transport while assisting interfacial superionic transport and subsequently enhance device performance, are comprehensively reviewed. This work highlights the recent advances of SBFCs and provides new methodology and understanding with significant importance for both fundamental and applied R&D on new-generation fuel cell materials and technologies.

“…Fire-through conditions generally increase the temperature up to around 800 °C [28][29][30][31][32][33]. We monitored the refractive index of the Si-rich SiN after the fire-through annealing (maximum temperature: 807 °C) by varying the NH 3 flow rate which can change the refractive index significantly.…”

Texture structure is usually fabricated on crystalline silicon (c-Si) solar cells to provide a low surface reflectance by an etching method such as alkali solution. In this study, we proposed nanoimprint lithography (NIL) as a fabrication process of the texture structure on the flat c-Si surface. The fabricated nanoimprinted texture which is a moth-eye structure by zinc oxide still has a high interface reflectance since the differences of the refractive index between the texture material and the c-Si substrate is large. We proposed an insertion of a Si-rich silicon nitride (SiN) layer between the texture and the substrate to solve this problem, and confirmed that the inserted Si-rich SiN shows remarkable benefits in terms of lowering the surface reflectance and providing a high carrier lifetime of the Si absorber, simultaneously.
