Special Issue Information

Dear Colleagues,

Buildings use about 40% of global energy and they emit into the atmosphere approximately 35% of GHG. Buildings also offer the greatest potential for achieving ever higher levels of energy efficiency and significant GHG emission reductions in developed and developing countries. There is an increasing need of encouraging energy efficiency in buildings, enhancing green technologies, and promoting advance thermal energy storage solutions. To improve energy efficiency and environmental performance in both new and existing building studies and to develop research on advanced materials and new technologies to be applied to the building envelope are required. The construction sector needs innovative materials and systems based on heat storage, thermal insulation, and the use of renewable energy customized for the current and future reality of the construction market.

Abstract
The operative temperature of a photovoltaic cell influences the electric conversion yield. This can be enhanced by cooling the panel. Among the studied solutions, phase change materials (PCM) exploit latent heat and absorb a large amount of energy at a nearly constant temperature. [...] Read more.
The operative temperature of a photovoltaic cell influences the electric conversion yield. This can be enhanced by cooling the panel. Among the studied solutions, phase change materials (PCM) exploit latent heat and absorb a large amount of energy at a nearly constant temperature. PCMs suffer from a low thermal conductivity. Under these premises the paper presents a hybrid graphene/fins/PCM cooling system to maximize efficiency gains and thermal recovery. An indoor laboratory characterization, under a solar simulator, compares the proposed model with a reference one (an identical, simple PV module) under fixed environmental conditions. Outdoor tests investigate the performances of the two systems under natural conditions. Indoor results show that the front temperature of the proposed PCM integrated module is averagely 6 °C less, with a peak of 8 °C, than the reference case. This means an increase in the electric yield of about 3%. Outdoor investigations prove that, when the PCM is solid and during the melting phase, the proposed system is averagely 1.12 °C and 4.87 °C colder than the reference case, respectively. The thermal efficiency is 30% and 65%, respectively. Once the melting process is completed, the performance becomes worse, and the hybrid panel is almost 3 °C warmer than the simple panel.
