PSAT is very around a 1U cubesat yet in a 1.5U bundle subsequent to the flight was accessible and it gave us more power for our NON-SPACE sun powered cells. We are utilizing standard silicon that are just half as effective as multi-intersection cells, however just cost 1% as

The specific material is modeling in only reliable for in-house applications instead of commercial. A complete solar cell information is usually provided by the manufacturer which leads design challenges in

Solar cell or photovoltaic (PV) systems usually transformed energy from the sun in to electric current. It can be measured in terms of ‘‘conversion efficiency’’, the proportion of solar energy transformed to electricity. (Henderson, Conkling, & Roberts, 2007) Sunpower primarily focused on the production of solar cell. But by moving in to wafer manufacturing it soon incorporated in to manufacturing of solar power module units. In general Sunpower manufacturing process needed approximately two times as many steps as the usual solar manufacturing process need and many of these steps were distinctive to Sunpower. Sunpower has nearly 15 -20 established cell manufactures, a handful of silicon – based cell manufacturing upstarts and a number of thin film solar companies offering potentially unsettling technologies.

Many of these conventional DC–DC converters have the disadvantages of operating at high duty-cycle, high switch voltage stress and high diode peak current. The conventional boost high step-up converter can provide very high voltage gain without operating at high duty-cycle by employing a coupled inductor, a switched capacitor and an additional diode. Non-isolated high step up converter overcomes this drawback. This converter reduces voltage stress on switch and diode by using additional one capacitor and rearranging components in conventional single switch high step-up converter. At the same time, the switch voltage stress is reduced greatly, which is helpful to reduce the conduction losses by using low power rated components and efficiency will increase. Single switch is used in the non-isolated high step up converter, thus reduce the entire cost of the converter. This non-isolated high step-up converter is used in many applications such as renewable energy system using low voltage energy sources such as fuel cells, solar panels,

Some of the key features of these components are ultra-small size, low insertion loss and high rejection. These components also ensure reliability in high power and temperature conditions. Advantages of these components are listed below:

Abstract— A novel single-stage high-power factor ac to dc converter with symmetrical topology which is compared with traditional full bridge series parallel resonant converter. Traditionally, an ac/dc converter consists of a diode-bridge rectifier followed by a bulky capacitor and a high frequency dc/dc converter. This kind of converter inevitably introduces a highly distorted input current, resulting in a low power factor. Single stage ac/dc converter with symmetrical topology can overcome this

High-voltage overhead conductors aren't coated by insulation. The conductor material is almost perpetually AN Al alloy, created into many strands and presumably bolstered with steel strands. Copper was generally used for overhead transmission, however Al is lighter, yields solely marginally reduced performance and prices abundant less. Overhead conductors square measure a trade goods provided by many corporations worldwide. Improved conductor material and shapes square measure frequently accustomed enable augmented capability and modernize transmission circuits. Conductor sizes vary from twelve mm2 (#6 yank wire gauge) to 750 mm2 (1,590,000 circular mils area), with variable resistance and current-carrying capability. Thicker wires would cause a comparatively tiny increase in capability as a result of the electrical phenomenon, that causes most of this to flow near the surface of the wire. owing to this current limitation, multiple parallel cables (called bundle conductors) square measure used once higher capability is required. Bundle conductors are used at high voltages to scale back energy loss caused by Saint Elmo's light.

The short and unpredictable nature of the conventional chemical batteries, along with the frequent replacements that they require, has created an acute need for a reliable, longer-lasting and rugged source of energy. Moreover Radars, spacecrafts, interstellar probes and other advanced communication devices require much larger power than that can be met by conventional energy sources.

Since the specific energy of a battery is determined by the product of the operating voltage and specific capacity, in order to meet the demanded characteristic of higher specific energy; higher operating voltage, and higher specific capacity need to be achieved. The higher operating voltage can be reached by finding cathodes and anodes such that their average difference of chemical potential is as large as possible while the safety is assured. Conventional cathode and anode materials used in LIB cells could only have a maximum operating voltage of about 4V per cell which needs to be higher if one wants to avoid using numerous LIB cells in series and parallel to meet the high voltage need of about 400 volts for electric cars for example. Similarity, the demanded characteristic of high specific capacity is reached if more efficient and chemically suitable materials other than LiCoO2 and graphite are used in a LIB cell.

The proposing team has worked on several renewable energy projects. The latest one is the highly competitive Google “Little Box Challenge” design competition, hosted by Google Company and IEEE Power Electronics Society [22], from Sept. 2014 to March 2016. Google offered one million dollar grand prize. Ximax team successfully entered the finalist and become one of the five best solar inverter design teams in the US and one of the best eighteen in the world. Although we did not win the final prize, we did prove that we are a world class design team. It gives high confidence that Ximax will succeed in this proposed project.

For our undergraduate project, we chose to work on something that excited the group intellectually - energy efficient thermal processes. We addressed the problem of high cell temperatures in solar photovoltaic panels by developing a unique cooling technology that increased their efficiency. The project won the First Prize in the annual project exhibition held by the Department of Mechanical Engineering. We recorded the surface temperatures and current outputs for an experimental and a reference solar panel at Bharat Heavy Electricals Limited, Bangalore. The experimental panel was cooled using a ceramic Cordierite honeycomb structure as the cooling module fitted to its rear face and water as the coolant. The cooling mechanism is based on the principle of a ‘ceramic heat pipe wick’
