Analysis to Improve the Life Span and Reliability of Satellites’ Solar panel ABSTRACT;
The many researchers’ keen interest of utilizing the space based solar power in various applications since 1970’s. The interest has boosted the search for ways to improve the lifecycle and reliability of solar panel in satellites. It is envisaged us to protect the materials from space dust and other environmental phenomena such as radiation which may affect materials and devices in deleterious ways. This paper mainly focuses on the selection of materials and the results of absorption coefficient, that how far a light with a specific wavelength energy can penetrate the materials being absorbed using the multi junction cells to increase the efficiency. The choice of the materials for each sub-cell is determined by the requirement for latch matching, current matching and high performance optoelectronic properties. The used method in a single junction cells have efficiency of 34% and the infinite junction cells of array can be improved to 87% under highly concentrated sunlight. These sources are helpful to mission reliability on longer time and success of missions. OJECTIVES;

Solar energy is a type of renewable energy, which means that the sun’s rays are a natural energy source; they do not need to be mined, extracted, or otherwise taken from some source. Many researchers and scientists are developing solar technologies to make them even more cost-effective, energy efficient, and environmental friendly. Solar energy is converted into electricity through solar panels. INTRODUCTION;
Next year (2013) will mark the 55thyear anniversary of the first practical use of solar cells. Silicon solar cells provided power to the Vanguard I satellite launched in 1958. Since that time, solar cells have powered virtually all spacecraft and the need for increasing powerful spacecraft solar arrays continues to drive the development of the highest efficiency solar cells. Although space solar cell efficiency has more than doubled over the past five decades, the majority of today’s terrestrial solar cells are made of the same materials as the Vanguard I solar cells. As terrestrial solar cell researchers and manufacturers have sought to reduce solar array costs to become more competitive with fossil-fuel-generated electricity, improvements in space solar cells have focused on performance. The performance are based on alternate selection of materials environmentally. Without the availability of suitable technology, the successful exploration and exploitation of outer space would be impossible. The eventual success of failure of a space mission may ultimately be decided by the performance of one piece of technology- an antenna for telecommunication, radar to observe the earth, or special lenses for a space telescope, solar panel for satellite and even each component are crucial so it is a very important role for expanding the life span and reliability of each components. The research approaches to increase cell efficiency by exploiting this model’s assumptions. After the analyzing going to test the single cell materials are subjected to increase the number of junctions. These method is going to give the high-efficiency in a solar concentrator systems. These systems concentrate on mirrors or lenses that increase the intensity of incident light from 300–500 times that of natural sunlight. The necessary things are doing the work as given below. 1.Selecting the materials
2.Analyse the characteristics
3.Environmental effects 4.Collecting the...
