Comparison of semi- spherical solar collector with flat plate solar collector
International Journal of Engineering & Technology, 2019 The efficiency of each solar system depends on the amount of radiation that it receives. The evident characteristic of solar energy is its change throughout the day and during different seasons. Another feature of this energy is the change of position of the sun in the sky relative to Earth.

Advanced Functional Materials, EarlyView.A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

Advanced Functional Materials, EarlyView.We demonstrate that halide composition determines phase morphology, governing distinct operating mechanisms in mixed halide perovskites. Phase segregating 75% Br compositions enhance solar cell performance, whereas intrinsically phase‐separated 95% Br compositions provide stable light emitting diodes.

Advanced Functional Materials, EarlyView.Solvent‐composition‐controlled film formation enables high‐performance (efficiency = 18.66%) and air‐stable terpene‐processed organic solar cells. An optimized eucalyptol/tetralin ratio of 50:50 (v/v) balances molecular solvation and aggregation kinetics, producing favorable nanoscale phase separation and vertical composition gradients.
