Summary: Dye-sensitized solar cells (DSSCs) have attracted attention for their low-cost processing, ability to work in diffuse light, and potential for building integrated photovoltaics (BIPV). However, their efficiency is low due to multiple issues. This study introduces a graphene/TiO2 scattering layer that enhances electron transport and light scattering. Results show that with 0.01 wt% graphene, a 33% higher photoconversion efficiency (PCE) was achieved compared to without scattering layer. However, PCE decreases at >0.01 wt% graphene due to loss of diffuse reflectance and higher optical absorption.

Summary: Fiber solar cells, woven into textiles, have shown potential in supplying electricity for wearables. However, achieving high power conversion efficiencies in real-world applications remains a challenge. A unique hybrid counter electrode was designed using metal current collector fiber, aligned carbon nanotube sheet, and porous titanium dioxide/poly(vinylidene fluoride-co-hexafluoropropylene) film. This design achieved a record power conversion efficiency of 12.52% and maintained efficiency below 10% after bending, twisting, or pressing for 1000 cycles. The integration of these fiber dye-sensitized solar cells with fiber batteries demonstrated an effective power solution for wearables.

Summary: Dye-sensitized solar cells (DSSCs) are gaining attention as alternatives to traditional photovoltaic solar cells due to their easy manufacturing methods, understandable operating mechanisms, and environmental friendliness. In these solar cells, the competition between electron-hole charge separation and recombination processes determines the fate of the excited electron, while the type of electrolyte determines the competition between recombination reactions and dye regeneration. Despite early studies on combining p-DSSCs and n-DSSCs to create t-DSSCs, the performance is usually poor due to the competing processes, necessitating improvements in DSSCs. This article focuses on the effects of using NiO as a working electrode and discusses the impact of sensitizer, redox couple, and transparent conducting oxide electrode on cell performance.

Summary: Surface passivation using a mixed salt has been shown to improve the performance and stability of perovskite solar cells. The length of the alkyl chain in the mixed salt can manipulate the crystal formation dynamics and enhance the (001) plane. The enhanced crystal orientation during surface recrystallization reduces trap density and suppresses charge recombination, leading to an increase in open-circuit voltage and fill factor.
