A white light emitting diode (LED) does not offer uniform irradiance in the visible region of electromagnetic spectrum. However, the additional irradiance in the blue regions is found to be complementary of the absorption spectrum peaks of human blood. Here, we have utilized such spectral characteristics of a typical white LED light as a source of white light interferometry for the measurement of...
We have reported InAs/GaAs and InGaAs/GaAs quantum dot solar cells (QDSCs) and the effect of rapid thermal annealing (RTA) on their optical properties. A thermal stability was observed up to 700°C, and further increase in temperature results in a blue shift in photoluminescence (PL) emission peak. A maximum open circuit voltage (Voc) of 0.33V was obtained for the InGaAs/GaAs solar cell (SC), whereas...
