Numerical Investigation of Solar Energy Driven Diffusion

The present work deals with the development of a diffusion absorption refrigeration cycle based refrigeration system operated by solar energy This study focuses on the thermodynamic modelling of NH 3 – H 2 O diffusion absorption refrigeration cycle with helium as pressure equalizing gas Results obtained from the parametric analysis show that 1 3% profit in refrigerating effect is observed

Simulation of Organic and Perovskite Tandem Solar Cells

As in the experimental work the single junction solar cells were implemented with both absorber materials sandwiched between PEDOT:PSS as HTL and a PFN/Al contact For the tandem simulation the single junction material parameter values were taken as starting values and were kept at the same order of magnitude in the optimization of the new parameters for the CuSCN HTL the ZnO ETL/interlayer
