--------------------------------------------------------------------------***---------------------------------------------------------------------------Abstract Since there have been tremendous increases in all of those technology and population, the need for energy is growing at such an alarming pace on a global scale. To fulfil the increasing need for energy in the future, it is crucial to develop renewable energy sources that are reliable, affordable, and unbreakable. As a way of reducing the long-term impacts of the energy shortage, solar energy offers many potentials and is easily available for free, along with other renewable energy sources. Because of the enormous demand of energy and the restricted availability for the primary valuable medium of energy generation (fossil fuel), the solar (PV) business is increasing at a constant rate around the globe. There are other non-cheaper sources. It is now cost-effective after years of intensive study that was done to hasten its development, and as a result, it has become a tool that can be used to improve the economic condition of developing nations and to support the lives of a large number of people who are living in poverty. When comparing to another types of non-conventional energy generating mediums, the solar (PV) sector is head and shoulders above the competition in terms of availability, cost-effectiveness, accessibility, capacity, and efficiency. This makes it a clear frontrunner for meeting the growing energy demand in next following years. This study will discuss recent advancements in solar energy in the previous decade and cover the many techniques that are utilized for the use of solar trackers, designing of solar cells and Solar cells in a variety of applications.

1. Introduction The major crucial challenge facing humanity in the twenty first century is finding ways to head off an impending energy catastrophe. The bulk of the world's population, which is still mostly impoverished, has long had increasing energy demands that have been the subject of continuous research. This has been done to prevent polluting our ecosystems, using up resources that will be needed by coming generations, and putting an undue amount of stress on regions of the world with abundant energy resources. The rapid population expansion and attempts made by the most densely populated regions of the world to progress their economies have resulted in an unprecedented increase in demand, which must be overcome in order to achieve this aim. The world's population has expanded by approximately 2 billion people in the span of only one generation, with a significant portion of that growth coming from emerging nations. Additionally, it is good to know that the demand for energy rises at a pace that is directly proportionate to the expansion of the economy. The number of regions in developing nations that do not have access to electricity has not greatly decreased, despite the fact that several initiatives, policies, and expenditures have been made to increase generating capacity. One of the primary reasons why residents in non-electrified villages are still economically disadvantaged is that they do not have access to a reliable source of electrical power. As a result, it is of the utmost importance to construct the necessary infrastructure and set up the essential resources for decentralized energy production in order to fulfill the requirements of the global energy market[1]. Although it is not a brand-new idea, renewable energy is quickly being recognized as a viable option to fossil fuels and other types of energy sources that are harmful to the environment[2]. It is possible for non-conventional energy mediums like bio gas, wind energy, sun, hydroelectricity, and geothermal to offer continual energy supply by making use of domestic mediums that are consistently accessible. It is becoming more probable that we will make the switch to renewable energy[3] systems as the price of fossil fuels continues to climb and the price of non-conventional energy mediums continues to fall. Sun energy and air power systems have, over the course of the previous three decades, seen continuous improvements in their performance characteristics and have seen explosive development in terms of sales[4]. The costs of both the initial investment and the electricity generated by such systems have seen considerable reductions in recent years. These changes have created market possibilities to both innovate and capitalize on developing markets in order to advance renewable energy solutions. This is particularly true when additional assistance is provided by both the government and the sentiment of the general public. The
