Night-Time Power Generation by Night Howler Cells: A Review
Mohammad Akram Qureshi,  Dr. Rajeev Arya,  Dr. Nilesh Diwakar
Everyday a large amount of solar radiation falls upon the Earth. Among a wide portion of frequencies radio waves, visible, infrared, ultraviolet and reach the Earth’s surface in the decreasing order as mentioned. A portion of this incident radiation gets absorbed in the atmosphere while the other portion is reflected back into space. The portion absorbed by Earth and its atmosphere regulates the temperature of Earth when there is no sun overhead termed as Earth’s albedo. Earth overthrows extra heat into atmosphere by radiative cooling phenomenon. This phenomenon takes place in long-wave infrared region of the electromagnetic spectrum. In order to generate power from this resource a number of infrared sensitive materials were studied on the basis of their radiation absorption and spectral properties. Amongst them most prominent results are given by Mercury-Cadmium-Telluride (HgCdTe). By doping different quantities of Mercury and Cadmium on Tellurium substrate a number of different bands of infrared absorbing materials could be generated. The HgCdTe PV cell was studied and the results were compared to that with the currently available PV cells. The results showed about one and a half times to two times more power generation in comparison.
Keywords- Radiative cooling, infrared radiation, Earth’s albedo, infrared sensitive materials etc.
