“…The glass cover above the PV module functioned to reduce the thermal energy lost. Meanwhile, the absorbing tube below the PV model was constructed from the copper pipe in a serpentine shape [22][23][24][25]. The pump and censor flow controlled the working fluid flow rate during the cooling circulation.…”

This study explores the efficiency of photovoltaic thermal (PVT) system using bio-nanofluid based on virgin coconut oil (VCO). This research proposes bio-nanofluid as dispersion media because of their potential in medium to high temperature applications in terms of thermal output, biodegradable, and renewable. Graphene nanoplatelets (GNP) were prepared in a mass fraction of 0.1% wt. Then, the ratio for the surfactant was a 1:1 nanoparticle. The surfactants used in this study were Polyvinylpyrrolidone (PVP), Sodium dodecyl sulfate (SDS), and Cetyltrimethylammonium bromide (CTAB). The two-stage method was used for the bio-nanofluid synthesis. Further, the samples were tested for physical and thermophysical properties. From the stability test, we discovered stable dispersion from VCO-GNP-PVP bio-nanofluid sample during the 30 days of testing. The bio-nanofluid samples also presented an increase in thermal conductivity following its stability, with the highest conductivity value (0.158 W/m.K) observed on the VCO-GNP-PVP sample. The efficiency test results on additive surfactant and flow rate show the optimum flow rate of 7 mL/s on VCO-GNP-PVP bio-nanofluid, with thermal and electric efficiency of 25.169% and 8.632%, respectively.

“…The results show that the perforated delta-winglets with circularity of 0.86, P B /H B of 0.5, α a of 450 and spacer length of 0 mm have optimum impact on Nu and f of the SWH. Singhy et al [9] developed a novel concentrated photovoltaic thermal system (CPVT) with combination of Fresnel lens (FL) and convex lens (CL). IV characteristics of PV module without lens, with FL and together with FL/CL determined during analysis.…”

The current research work involves the design and performance assessment of a solar still, which is a conventional single‐slope basin‐type solar still (CSSBTSS) and a modified single‐slope basin‐type solar still (MSSBTSS) under the meteorological conditions of Solan city, Himachal Pradesh, India (30.90° N, 77.09° E). The individual and the combined effect of different sample quantities of sensible Himalayan Rambaan fibers (HRFs) and mass of latent paraffin wax (PW) A48 on the performance of MSSBTSS is evaluated and compared with CSSBTSS. The use of HRF material enhanced the evaporation rate significantly and improved the daytime distillates. Besides, different masses of latent PW filled inside the aluminum tubes improved the nocturnal distillates. For the analysis, three cases have been considered which are, namely: Case 1, solar still with sensible HRFs (MSSBTSS‐HRF); Case 2, solar still with latent PW A48 (MSSBTSS‐PW); and Case 3, solar still with sensible and latent material (MSSBTSS‐HRF‐PW). The results showed that the maximum thermal efficiency for Cases 1 and 2 was improved by 30.02% and 42.41% with five sample quantities of HRF material and 5000 g of PW. For Case 3, the maximum energy efficiency was 90.71% with a gain of 45.16% over CSSBTSS. The economic analysis concluded that the cost per liter of distillate yield produced using MSSBTSS‐HRF‐PW and CSSBTSS is ₹1.5 and ₹1.6, respectively. These outcomes showed the great potential of MSSBTSS‐HRF‐PW approach towards enhancing the overall performance and cost‐effectiveness of solar still.
