Furthermore, various complex phenomena, including light scattering, recombination of electron-hole pairs, and dye degradation, in the photoactive layers of DSSCs can occur when the intensity of incident light is changed by varying the beam focus of solar concentrator [16]. The question arises as to how we can optimize the effects of the intrinsic cell structure and solar concentrator when concentrated light is incident on the photoactive layer structures in DSSCs. In this work, we systematically investigated the effects of using a light-scattering layer selleck chemicals llc in the photoelectrodes of DSSCs along with studying the effects of using a condenser lens-based

solar concentrator on the photovoltaic performance of DSSCs. Briefly, three different photoelectrode structures fabricated with a T25/T25-accumulated double layer (T25/T25 DL), a T25/T240-accumulated double layer (T25/T240 DL), and a T240/T240-accumulated double layer (T240/T240 DL) were examined for verifying the effects of using a light-scattering layer under intensified light irradiation conditions tuned by a condenser

lens-based solar concentrator. Here, T25 and T240 indicate EX-527 commercialized TiO2 nanoparticles (NPs) with an average diameter of approximately 25 and 240 nm, respectively. With the optimized design of the condenser lens-based solar concentrator developed in this approach, we report a novel T25/T240 DL-based DSSC system with condenser lens-based NVP-BGJ398 order solar concentrator that exhibits a photocurrent output of approximately 11.92 mA, an open circuit voltage of 0.74 V, and power conversion

efficiency (PCE) of Phosphatidylinositol diacylglycerol-lyase approximately 4.11%, which exhibits a much better photovoltaic performance compared to T25/T25 DL- and T240/T240 DL-based DSSCs with condenser lens-based solar concentrator. Methods Commercially available TiO2 NPs (T25, Degussa; T240, Sigma Aldrich, St. Louis, MO, USA) were used without further treatment. In order to prepare TiO2 NP paste for the screen-printing process, 6 g of TiO2 NPs, 15 g of ethanol, 1 mL of acetic acid (CH3COOH), and 20 g of terpineol were mixed in a vial and sonicated for 1 h. A solution of 3 g of ethylcellulose dissolved in 27 g of ethanol was separately prepared and subsequently added to the TiO2 NP-dispersed solution, which was then sonicated for 30 min [5, 17]. As a photoelectrode layer, TiO2 NP-accumulated thin layer was applied via a screen-printing process on a fluorine-doped tin oxide (FTO) glass (SnO2:F, 7 Ω/sq, Pilkington, Boston, USA) with a photoactive area of 0.6 × 0.6 cm2, as shown in Figure 1. The T25 single layer (T25 SL), T25/T25 DL, T25/T240 DL, and T240/T240 DL were separately prepared for comparison purposes. The resulting TiO2 NP-accumulated layer formed on the FTO glass via the screen-printing process was then sintered in an electric furnace at 500°C for 30 min and subsequently immersed in anhydrous ethanol containing 0.
