In this paper, the novel application of organic/inorganic perovskite hybrid materials isproposed for grid-connected Photo-voltaic (PV) cells. The perovskite hybrid cells attracted a lot of interest due to their potential in combining advantages of both components. Looking to the future, there is no doubt that these new generations of hybrid materials, born from the very fruitful activitie...

Decisions can be taken to increase energy efficiency and to mitigate the emissions to the environment by examining the energy audit and greenhouse gas (GHG) emissions footprint of crop production in different ways and in different regions, with comparable principles. In this study, energy consumption and energy indices of tomatoes production in four regions of Iran including East Azerbaijan...
