Efficiency Optimization of Si-nanowire Heterojunction Solar Cell by Band Gap Engineering See

The Si Nanowire arrays offer a distinct advantage in solar cell design due to the tunable band gap with improved performance. By increasing the SiNW emitter band gap from 1.1 eV to 1.9 eV, the work demonstrates a significant efficiency boost from 15.2% to 21.7% for the optimized band gap of 1.5 eV. An increased open-circuit voltage primarily drives the improvement, as the wider band gap creates a larger valence band offset, which suppresses hole injection and reduces interface recombination. ...

Study of Charging in Phase Changing Material using the Unused Heat Available in A Diesel Engine Exhaust See

Cold start of an internal combustion (IC) engine causes higher fuel consumption, increased exhaust emissions, and increased wear on engine components. At the same time, a significant percentage of fuel energy is rejected to the surroundings as waste heat through the tailpipe. This waste heat can be stored using a proper storage material for later purpose. This experimental investigation studies the charging of a phase change material (PCM) filled in a latent heat thermal energy storage (LHTES...
