Power Point

This paper defines the design of UPS system with the help of sun tracking system, as a source for chargingthe battery to provide the backup power when the regular power source fails. This authentication is provided by obtaining the theoretical calculation of output power, output current and output voltage which are developed due to solar radiations. In this system, if the primary load is not in use, then the power is automatically switching over to secondary load. Basically, an UPS is electrical equipment that is used at the time of emergency. The battery bank is charged with the help of solar photovoltaic cell. This paper proposed an approach to understand the peak power point of the sun based on analysis of the open-circuit voltage of the PV panel. This project provides the power supply to a load which is uninterruptible, by automatically selecting the supply from the main source or inverter.

Extra Oxygen

Studies previously carried out to improve the Se–CdO photovoltaic cell have emphasized optimization of the deposition of the CdO by direct current (DC) reactive sputtering. Attention has now been turned towards improving the deposition, doping, and heat treatment of the polycrystalline selenium base. It has been found that heat treatment of the selenium film on its substrate of aluminum and bismuth in air or oxygen prior to CdO deposition results in an increase in the illuminated open-circuit voltage (Voc) of the cell. The effect increased with increase of annealing temperature from 150 to 195 °C and in going from dry to wet oxygen. No increase in Voc was found by heating in nitrogen. The effect could be due to the formation of higher stoichiometric and hence higher resistivity CdO at the Se–CdO junction, arising from the presence of extra oxygen on the selenium surface.
