There has been minimal research to evaluate the life cycle of PV-green roofs. Furthermore, the life-cycle cost and benefits (e.g. environmental, social, and economic) of PV-green roofs are unknown, and there are still hidden costs required for long-term maintenance (Lamnatou and Chemisana, 2014).
Maggio et al. (2020) performed a techno-economic-financial evaluation of a system to be located in Messina (Italy) to produce green hydrogen to be sold as a feedstock for industries and research centers; they found that investment to construct a small-scale PV-based hydrogen production plant can be remunerative .

Therefore, the PV-green roof is an effective strategy for producing green energy in urban areas. (Chemisana and Lamnatou, 2014) studied the energy performance of PV-green roofs in Spain, and indicated that the PV-green roof is better practice for energy production as compared to PV-gravel roof.

Deserts account for 17% of the world''s land area, mainly distributed in Asia and Africa (Cherlet et al., 2018; Durant et al., 2012).With the desertification caused by climate change and population growth, deserts have continued to expand in recent decades (Huang et al., 2016; Reynolds et al., 2007).The harsh environmental conditions of the desert seriously
Consolidated tables showing an extensive listing of the highest independently confirmed efficiencies for solar cells and modules are presented. Guidelines for inclusion of results into these tables are outlined and new

An experimental study on the rooftop garden at the University of Hong Kong during a sunny summer, with a PV system on the green roof and another one on a bare roof, showed that the PV-green roof generated around 4.3% more electricity when compared to the PV-bare roof.
However, a growing number of studies suggest that integrating PV with green roofs provides reciprocal benefits to both PV electrical production and green roof communities (Schindler et al., 2016). Green roofs appear to improve electricity production by PV (Chemisana and Lamnatou, 2014; Köhler et al., 2007), and the presence of PV, by
In the classic case, every photon absorbed in a solar cell produces at most one electron–hole pair. Kodolinski et al. (1993) showed quantum efficiencies higher than 1 in the short-wavelength range of a-Si solar cell. This can be explained as an optically induced Auger mechanism: the energy in excess of the bandgap that one of the carriers receives from a high
PV panels become less efficient as they become warmer, at a rate of 0.025% per degree Celsius at ambient temperatures over 28 °C (Ubertini and Desideri, 2003), so panel efficiency can be improved by cooling the surface of the panel.Since green roofs are cooler than black roofs (Scherba et al., 2011), and heat up more slowly than a white roof, they are
In 2017, Vilanova et al designed a new compact and optimised PV-PEC tandem cell with 50 cm 2 photo-active area named as Cool PEC cell as shown earlier in Fig. 8(d) A.A. Basheer et al. Water photo splitting for green hydrogen energy by green nanoparticles. Int J Hydrogen Energy (2019)

The actual yield is however also extremely dependent on the location and on the installation conditions (Guo et al., 2013, Nussbaumer et al., 2015). An important factor for the output of vertically installed bifacial systems is the mutual shading by adjacent rows, which requires a large row distance and low GCR to limit the shadowing losses.
Ran and Tang (2017) used DesignBuilder to evaluate the energy savings of combining a green roof and ventilation in a warehouse building in Shanghai, China (Ran and Tang, 2017). The simulation results revealed that the green roof combined with ventilation could save up to 26.7% of the energy used.
Solar energy is used whether in solar thermal applications where the solar energy is used as a source of heat or indirectly used as a source of electricity in concentrated solar power plants (Wilberforce et al., 2019b; Peinado Gonzalo et al., 2019), used directly in generating electricity in solar PV (Ram et al., 2018; Laib et al., 2018; Rezk
