Critical Analysis of Enhanced Photovoltaic Thermal Systems: A Comparative Experimental Study of Pcm, Teg, and Nanofluid Applications

Published: Jan. 1, 2024

Phase change materials (PCM), thermoelectric generators (TEG), and nanofluids are popular methods investigated for improving conventional photovoltaic thermal (PVT) systems, particularly in warm climates where high temperatures negatively impact (PV) power output energy efficiency. This experimental study evaluated the effects of 32 °C melting point PCM TEG integration on PVT units, as well 42 nanofluid incorporation concentrated (CPVT) units. Technical, exergetic, economic performance were compared using a small-scale module. Low-cost commercially available used to construct all Industrial metal waste was introduced enhance conductivity paraffin wax salt hydrate PCMs. The results indicated that applying PCMs, porous media, concentrator plates increased generation, potentially offsetting their higher initial cost achieving an approximately $0.135/kWh. However, implementation remained uneconomical, leading 15-35% increase cost. water-based CPVT unit, enhanced with copper fins, demonstrated best technical performance, electrical, thermal, exergy efficiencies 15.5%, 37.4%, 16.7%, respectively, more than 20% reduction cell temperature. also revealed severe structural changes caused by corrosion metallic hydrated PCMs could alter 30%, impacting heat storage capacity. Conversely, incorporating chips non-hydrated facilitated reaching state within 30-60 minutes.

Tandem Atmospheric Water Harvesting and Passive Cooling Enabled by Hygroscopic Biopolymer‐Based Aerogels

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 16, 2025

Abstract Atmospheric water harvesting (AWH) provides a promising pathway to alleviate global stress. However, in arid areas, how solve the local drought problem while making full use of other wasted energy and improving resource utilization efficiency is still challenge. Here, salt‐based biodegradable photothermal aerogels with vertical channels are constructed efficiently utilize waste heat from photovoltaic (PV) panels for tandem atmospheric passive cooling. Specially, hydrogen bonding interactions ionic cross‐linking aerogel porous skeleton together ensure material's stability. This has high‐water adsorption capacity (1.4–5.7 g·g −1 at 30–90% relative humidity (RH)), solar‐powered production up 1.80 ·day . After integrating PV panels, collection evaporation processes result fresh‐water 0.033 kg·m −2 ·h , panel power generation increases by 2.9%. work demonstrates great potential AWH technique combined cooling fully low‐grade energy, promoting development advanced energy‐water cogeneration.
