Summary: This study proposes a passivation strategy by introducing CuAlO2 (CAO) into the heterojunction interface (HEI) to achieve efficient Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells. The presence of CAO promotes the formation of a thicker Cu-deficient shallow bulk, reducing carrier recombination at absorber and HEI, resulting in improved cell efficiency.

Summary: This study investigates the effects of TCO work function on the performance of TCO/SiO2/n-Si heterojunction solar cells. The results show that the work function significantly influences the efficiency and J-V curve shape of the devices. Additionally, the band offsets at the SiOx/n-Si interface also play a crucial role in the device performance. Two mechanisms of the S-shape J-V curve formation are proposed.

Summary: Incorporating an optimized nano-dimer structure into a-Si:H ultra-thin solar cells can significantly enhance the deliverable short-circuit current and reduce the total reflectance by about 50%. The nano-dimer structure made of high-index refractive material like GaP plays a key role in efficiently scattering light and increasing absorption in the active layer.

Summary: In this study, the possibility of reducing indium consumption in silicon heterojunction solar cells was investigated through the use of ultrathin ITO layers and SiN:H capping dielectric layers. The results showed that combining ITO layers below 10 nm with nc-Si:H nanocrystalline layers can achieve higher module efficiencies, while using ultrathin ITO layers on the rear side is not optimal. UV and damp heat tests indicated that modules with thinner ITO layers have enhanced reliability.

Summary: A broadband thin radar absorber based on a periodic frequency selective surface is proposed, which achieves over 90% absorption in the C-band, X-band, and Ku-band, and over 80% absorption at a 40-degree incident angle. The absorber also provides a relative bandwidth of 130% through multiple resonances, showing significant competitive advantages in reducing electromagnetic interference.

Summary: The solar cell device architecture is crucial for achieving high efficiency and photovoltaic action. In this study, a dual-absorber solar cell with two band-aligned absorbers of different bandgaps is demonstrated, enabling absorption of a wider range of the solar spectrum and resulting in higher short-circuit current. The analysis reveals a narrow range of optimal parameters for net efficiency gain in the dual-absorber design, with interfacial defect and band offset playing essential roles in its efficient functioning. Comparison between single-, double-, and triple-absorber configurations highlights their performance enhancement and synergetic spectrum utilization. The proposed dual-absorber design offers a straightforward approach and comparable performance to a tandem device, thus presenting a potentially cost-effective solution for solar cells.

Summary: The authors report the formation of high-quality Cu2MnSnSe4 thin films on glass substrates using electron beam deposition. The films demonstrate a polycrystalline structure after annealing and have been characterized for their optical properties. The study also evaluates the nonlinear optical parameters and electric conductivity of the samples, as well as the solar conversion efficiency of a heterojunction device. The results suggest that Cu2MnSnSe4 could be a promising absorber layer for thin-film solar cells.

Summary: We examined the relationship between the efficiency of the solar absorber and operating temperature and developed solar absorber devices with excellent performance. One of these devices has a solar spectral absorption of 95.6%, ultra-low emission rate of 5.7%, and optical-to-thermal conversion efficiency exceeding 90% under working temperatures of 600 K. It has the potential to surpass the Shockley-Queisser limit in solar power generation systems.

Summary: The study reveals that thermal annealing negatively affects the charge carrier selectivity and performance of organic molecules with a permanent dipole moment used as electron-selective contacts in silicon heterojunction solar cells. This is attributed to decreased tunneling efficiency through the dipole layer due to the decomposition of materials, leading to a less conductive interfacial layer and a decline in open-circuit voltage.

Summary: We introduce an effective method for doping copper indium sulfide selenide (CISSe) with different alkali metals by pre-depositing an alkali chloride layer. The alkali chloride layer is sprayed onto the substrate surface before spray pyrolysis deposition of copper indium disulfide (CIS) films and selenization. The alkali-doped CISSe films prepared by the pre-deposition method show improved film compactness and larger grain size compared to undoped films. The alkali atoms with larger size result in wider band gap of CISSe film.

Summary: Layers of germanium nanowires were grown on titanium foils using metal-assisted electrochemical reduction. The addition of sodium silicate improved the crystallinity and size of the nanowires. Ge nanowire films were prepared by removing and redepositing the nanowires, and their electrical conductivity was studied. The presence of silicon impurities in the nanowires affected the conductivity, and the films exhibited a strong sensor response to different liquid vapors.

Summary: This study investigates the effect of electrolyte solution temperature on the morphology and properties of CuOx nanostructures. The results show that increasing temperature leads to the formation of CuO nanosheets instead of Cu(OH)2 nanorods. Additionally, the degree of light reflection decreases with higher electrolyte temperature.
