The high‐power conversion efficiency of flexible perovskite photovoltaics (PPV) at low light environment and their low‐cost manufacturing processes, render PPV superior to conventional rigid photovoltaics targeting indoor applications. However, various parameters related to materials, architecture, processing, and indoor characterization need to be optimized further toward improving indoor PPV (iPPV) efficiency, stability, and ecotoxicity. This work provides an overview of the recent progress, trends, and challenges in the field and suggests a holistic approach toward a viable design and integration of iPPVs into Internet of Things (IoT) platforms without any compromise on safety and cost effectiveness. The key impact of selecting proper materials and fabrication techniques, as well as optimizing the active area and architecture is described. Certain peculiarities of the indoor lighting conditions are discussed that can be addressed by proper simulation tools, including the understanding of the charge‐transfer mechanism, the diversification of the lamp types, as well as identifying the requirements for the production, standardization, and installation of iPPVs associated with IoT devices. A multidimensional engineering approach that considers aspects of architecture, light technology, load specifications, materials, processing, safety and cost, is proposed as a path toward accelerating iPPV market uptake for households, businesses, wearables and Industry 4.0 applications.

Liquid electrolytes are known to have high conductivities. However, they suffer from leakage, corrosion of electrodes and other stability issues. Solid polymer electrolytes eliminate the problems of liquid electrolytes at the cost of lower conductivity. Quasi-solid-state polymer electrolytes (QSSPE) overcome the shortcomings of both liquid electrolytes and solid polymer electrolytes. In this work, QSSPE is prepared by incorporating poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) in a propylene carbonate (PC) and 1-methyl-3-propyl imidazolium iodide (MPII) liquid electrolyte. Fourier transform infrared (FTIR) studies have been carried out to investigate the interactions among PVdF-HFP, PC and MPII. A comprehensive spectroscopic investigation on ion-solvent-polymer interactions helps to understand the mechanism of ionic conduction in the PVdF-HFP/PC/MPII electrolyte system. Interaction between MPII and PC has occurred from the changes in the ν(C=O), ν(C-O) + ω(C-H), ω(C-H) + δ(C-H) and τ of ring of PC as well as the C-N bond oscillation and of (N-C-H) of MPII. Interaction occurs via the coordination of MPIm+ cations with both oxygen atoms of PC. Complexation between PVdF-HFP and MPII has been noted. MPII suppresses the non-polar α-phase and induces the polar β and -phases of PVdF-HFP. Shift of peaks belong to the CF2 and CF3 groups of PVdF-HFP suggests the complexation occurs at the fluorine atoms in CF2 and CF3 groups. Evidence of interaction between PC and PVdF-HFP has been manifested through the change of the ν(C=O), τ(C-H) + δ(C-H) and ν of the CF2 group of PVdF-HFP. Disappearance of non-polar α-phase of PVdF-HFP is noted in the presence of PC. From this work, the authors hope to shed some light on understanding the conduction mechanism in PVdF-HFP:PC:MPII electrolytes. Understanding the conduction mechanism is important in order to find ways for conductivity improvement.

“…The location of the electrolyte as the redox reaction taking place has a great influence on the performance of DSSC. DSSC electrolytes include quasi-solid, solid electrolytes [14][15][16][17][18][19][20], and liquid electrolytes [21][22][23][24][25][26][27][28][29][30], of which liquid electrolytes are the most commonly used. Although liquid electrolytes have had problems such as solvent volatilization and electrode leakage corrosion [20,21], the preparation of solid and quasi-solid electrolytes have been complex and costly.…”

The electrolyte is one of the key components of dye-sensitized solar cells’ (DSSC) structure. In this paper, the electrolyte formulation of a new DSSC with external photoanode structure was studied. Based on the idea that the electrolyte should match the light absorption and light path, iodine series electrolytes with different concentrations were configured and used in the experiment. The results showed that the external photoanode structure solar cells assembled with titanium electrode had the best photoelectric conversion ability when the concentration of I2 was 0.048 M. It achieved the open circuit voltage of 0.71 V, the short circuit current of 8.87 mA, and the filling factor of 57%.
