The improvement of solid-state dye sensitized solar cells requires identification and understanding of hole transport material properties at various deposition process that limit the energy conversion efficiency. A well-studied of this hole collectors properties, a high efficiency ss-DSSC is highly achievable. In this research work, the copper (I) iodide (CuI) had been deposited by spin coating and mist-atomization technique. The thin films characteristics of surface morphology and electrical properties and its effect to the photovoltaic performance were investigated. The thin films morphology examined by FESEM shows smaller CuI crystal size deposited by spin coating (S1) of ~30nm. Even though, smaller particle size of hole conductor is desirable in order to achieve high pore penetration, the thin film thickness and the electrical resistivity are also essential. The CuI thin films deposited by mist-atomization (M1) shows a low resistivity of 1.77 x 10-1 Ωcm which will greatly affect the device performance. The photovoltaic performance of ss-DSSC at different method CuI deposition shows the highest efficiency of 1.05% for sample (M1) while the ss-DSSC fabricated with S1 sample shows the lowest conversion efficiency of 0.02%. The appropriate crystals size of CuI, film thickness and the electrical resistivity greatly contributed to the high filling fraction of the porous TiO2 layer and hence the cells performance.

Chlorophyll a derivatives were integrated in “all solid-state” dye sensitized solar cells (DSSCs) with a mesoporous TiO2 electrode and 2′,2′,7,7′-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene as the hole-transport material. Despite modest power conversion efficiencies (PCEs) between 0.26% and 0.55% achieved for these chlorin dyes, a systematic investigation was carried out in order to elucidate their main limitations. To provide a comprehensive understanding of the parameters (structure, nature of the anchoring group, adsorption …) and their relationship with the PCEs, density functional theory (DFT) calculations, optical and photovoltaic studies and electron paramagnetic resonance analysis exploiting the 4-carboxy-TEMPO spin probe were combined. The recombination kinetics, the frontier molecular orbitals of these DSSCs and the adsorption efficiency onto the TiO2 surface were found to be the key parameters that govern their photovoltaic response.

Sensitization of heavy metal free organic dyes onto TiO2 thin films has gained much attention in dye sensitized solar cells (DSSCs). A series of new kojic acid based organic dyes KA1–4 were synthesized via nucleophilic substitution of azobenzene bearing different vinyl chains A1–4 with kojyl chloride 4. Azo dyes KA1–4 were characterized for photophysical properties employing absorption spectrometry and photovoltaic characteristic in TiO2 thin film. The presence of vinyl chain in A1–4 improved the photovoltaic performance from 0.20 to 0.60%. The introduction of kojic acid obtained from sago waste further increases the efficiency to 0.82–1.54%. Based on photovoltaic performance, KA4 achieved the highest solar to electrical energy conversion efficiency (η = 1.54%) in the series.

The long-term stability of liquid-state dye-sensitized solar cells (liquid-DSSCs) is a primary problem for the upscaling and commercialization of this technology. The solid-state dye-sensitized solar cell (ss-DSSC) has been instigated to overcome the liquid-DSSC’s inherent production and instability issues and advancement has been made to achieve low-cost high-power conversion efficiency. The photovoltaic performance of ruthenium-based complex Z907 dye was studied in ss-DSSCs using a solid-state polymerized conductive polymer as hole-transporting material (HTM). We investigated the long-term stability of both liquid and solid-state DSSCs and the findings revealed an improved photovoltaic performance and long-term stability of ss-DSSC. This mainly depends on the transport phenomena of the HTM throughout the interface. The present results show a pavement for manufacturing highly stable and inexpensive ss-DSSC and the practical use is promising.

We report an inexpensive method using solvent-swollen poly(methyl methacrylate) as a sacrificial template for mesoporous titanium oxide thin films with tunable meso/nano morphology. The conversion efficiency reaches 4.2% despite using a solid-state electrolyte, which circumvents the longevity issues of liquid electrolytes. The cells show a large short-circuit photocurrent density of 7.98 mA, open-circuit voltage of 0.78 V, and maximum conversion efficiency of 4.2% under air-mass 1.5 global illumination. At higher titania precursor ratios, nanodisk particles are formed that increase light scattering and double the efficiency over our previous reports. The tunability of the semiconductor morphology and all solid-state nature of the cells makes the method a viable alternative to existing solar cell technology.

The leakage and volatilization of liquid electrolytes limit the commercialization of dye-sensitized solar cells (DSCs). As solid-state (ss) hole-transporting materials, free from leakage and volatilization, biscarbazole-based polymers with different molecular weights (PBCzA-H (21,200 g/mol) and PBCzA-L (2450 g/mol)) were applied in combination with additives to produce ssDSCs. An ssDSC with PBCzA-H showed a better short-circuit current (Jsc), open-circuit voltage (Voc), and fill factor (FF) than a device with PBCzA-L, resulting in 38% higher conversion efficiency. Compared to the PBCzA-L, the PBCzA-H with a higher molecular weight showed faster hole mobility and larger conductivity, leading to elevations in Jsc via rapid hole transport, Voc via rapid hole extraction, and FF via lowered series and elevated shunt resistances. Thus, it is believed that PBCzA-H is a useful candidate for replacing liquid electrolytes.
