The solar cell performance increased with the increase in TiCl 4 concentration up to 0.5M and leveled off. The best solar cell showed a short-circuit current density ( J sc ), open-circuit voltage ( V oc ), fill factor (FF) and efficiency ( 畏 ) of 12.75mA/cm 2 , 795mV, 69.2% ...
they collect solar energy, use some of it, and store the rest for use at night. For performance improvement of such aircraft, the harvesting rate of solar energy should be improved in the daytime. Gao et al.17studied the most up-to-date ways for collecting...
Further to this, Mn is usually enriched up to 60 times compared to the normal abundances it attains in soils and sediments (e.g. Tan et al., 2006). High adsorption capacity of soil FeMn nodules was shown as a factor that effectively controls the dynamics of many toxic metal pollutants ...
Also when In/S ratio was altered to 1.2/12, the short circuit current density increased to 17.8mA/cm2 with an improved fill factor of 32% and efficiency remaining as 2%. Thus Cu/In and In/S ratios in the precursor solutions play a crucial role in determining the cell parameters....
An efficiency of 0.6% (fill factor -37.6%) was obtained. Cu diffusion to the In2S3 layer, which deteriorates junction properties, is inevitable in CuInS2/In2S3 cell. So to decrease this effect and to ensure a Cu-free In2S3 layer at the top of the cell, Cu/In ratio was reduced ...
