“…Nevertheless, such a solution was not effective due to low thermal conductivity of a container and its small contact area with the panel. Based on the most recent reports in the literature, PCM can effectively influence temperature of PV panel when it is placed in the plastic bag [10], aluminum container with different fins [13,14] or when being integrated within building envelope as a PCM gypsum board [15].…”

Due to the fact that efficiency of PV panels decreases by approximately 0.5%/K, possibilities to stabilize the temperature on the panel's surface are considered in this paper. The aim of this investigation is to determine the transition temperature of PCM layer that allows avoiding rapid temperature fluctuations on the PV back surface. To meet the stated goal, dynamic simulations of thermal and electrical performance of PV/PCM panels were carried out using ESP-r software. Based on the obtained results, it can be concluded that additional PCM layer on the back side of PV panel can effectively increase the efficiency of electricity production with PCM transition temperature about 20°C.

“…The effect of natural convection inside the air gap of a BIPV, however, is a complex issue. However, depending on the level of details and parameters studied, the heat transfer across these systems can be modelled using a simple thermal network model [13], [14] to a more complex, CFD. Moshfegh & Sandberg [15] have carried out CFD simulations of naturally ventilated PV façades, Yang et al [16] developed a numerical model for a natural ventilated PV roof and façade system, and Brinkworth et al [17] for a natural ventilated PV in a roof included a comparison with experimental results.…”

During the last 20 years the research of Building Integrated Photovoltaic Systems (BIPV) related with different techniques and concepts has been widespread, but rather scattered. In BIPV systems photovoltaic panels functioning as an integral part of the building envelope, therefore, enhances the aesthetic appeal of the building. In addition of providing renewable energy, they may also contribute to improving the indoor climate when thermal energy released during the conversion process is withdrawer efficiently, passively or actively recovered (BIPV/T). The increase in BIPV/T research since 1990s, is a consequence of the growing interest of the construction industry in offering new alternatives to traditional approaches. The paper is reporting in the first part, a BIPV classification focused on the building integration aspect and on the characterization of the main parameters involved rather than on technologies used or the performance aspects. In the second part, the paper is focused on reporting the experimental results from a particular application, a case study developed in Portugal, where a thermal storage element, Phase Change Materials (PCM) integrates the BIPV.

“…A model of a BIPV-PCM system installed in an office façade has been validated using field testing. The maximum electrical efficiency has been shown to reach 10% with thermal efficiencies of 12% [17]. An investigation into the concept of a BIPV-PCM system found the design advantageous due to the reduction of materials required during construction, removal of heat in the summer by PCM and the harnessing of solar energy reduces the need for conventional grid power [18].…”

Photovoltaic/ thermal (PV/T) systems integrate photovoltaic and solar thermal technologies and have the added advantage of producing both electrical and thermal energy simultaneously. This study has been carried out to investigate the performance of a PV/T phase change material (PCM) system under experimental climatic conditions. Electricity is generated by the PV during daylight hours and the heat produced is absorbed and stored in PCM. Water flows through a pipe network within the PCM and absorbs the stored heat in the PCM. In the PV/T-PCM system, water remained at a higher temperature for an extended period of time as well as shifting the time period of available heat when compared to the reference systems.
