The main task of HVAC systems in the cooling condition is to remove heat from indoor environment to outdoor environment. HVAC systems are complex networks of various processes, e.g., heat transfer, heat–work conversion, heat–humidity conversion, etc. These processes correspond to equipment...

Inorganic lead-free Cs 2 AgBiBr 6 double perovskite is a promising material for solving the toxicity and the instability of organic-inorganic hybrid perovskite. However, due to the poor interface contact and inferior perovskite film quality, the open-circuit voltage and the power conversion...
