Summary: The improvement of photoconversion efficiency and operational stability of dye-sensitized solar cells (DSSCs) under environmental conditions is a major challenge for commercialization. Two approaches, namely increasing light scattering via embedding mesoporous TiO2 beads and delaying electrolyte leakage using gel polymer electrolyte, were employed to address this challenge. The highest photoconversion efficiency of 9.8% was achieved for the photoanode based on mesoporous TiO2 beads in the presence of gel polymer electrolyte, demonstrating longer operational stability under realistic ambient conditions.

Summary: Dye-sensitized solar cells (DSCs) are a promising alternative photovoltaic technology with low cost and high performance for indoor applications. Solid-state DSCs (ssDSCs) have been developed to address the problems of electrolyte leakage and electrode corrosion. However, the power conversion efficiency of ssDSCs is generally lower than traditional liquid DSCs. To overcome these limitations, the authors have developed an in situ photoelectrochemical polymerization (PEP) approach to synthesize polymer hole transport materials (HTMs) in the porous electrodes, enhancing pore infiltration fraction and conductivity. This review provides a comprehensive overview of material engineering and interfacial optimization for ssDSCs, as well as recent advances in PEP and its impact on device performance.

Summary: Thin films of solid-state polymer electrolytes (SSPEs) have been developed for dye-sensitized solar cells (DSCs) for the first time. Gel-electrolytes are prepared by utilizing a blend of poly(ethylene oxide) (PEO)/polyethylene glycol (PEG) and an acetonitrile-based iodide liquid electrolyte, and then cast onto a glass substrate to fabricate solvent-free SSPEs by evaporating the solvent. The SSPE films are sandwiched between photoelectrodes and counter electrodes to assemble the solid-state DSCs, and the PCE can be improved by introducing TiO2 nanofillers in the SSPEs. The high stability of the solid-state DSCs is demonstrated with a retention of 98% of their original efficiency after a 700-hour test period.

The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells.

In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.
