dc.description	We will begin our discussion of PV technology with a summary of the history of solar energy. Already in the seventh century BC, people used split glasses in the light of the sun to concentrate and so on. Later the ancient Greeks and Romans used mirrors for the same purpose. In the eighteenth century, the Swiss physicist Horace-Benedict de Saussure created a heating mesh, a kind of tiny greenhouse. When exposed to direct solar radiation, the temperature in the innermost box can rise to a value of 108 ° C; These boxes could be considered the world’s first solar collector to boil water and be warm enough to cook. In 1839, the French physicist Alexandre-Edmund Becquerel discovered the photovoltaic effect when he was just 19 years old. He observed this effect in an electrolytic cell consisting of two platinum electrodes placing an electronic signal. In the 1860s and 1870s, French inventor Augustine Mouchot built the world's first solar- powered steam engine using the Parabolic Trot solar collector. Mouchot was inspired by his belief that coal resources were limited. At that time, coal was the source of energy for steam engines. However, as coal became cheaper, the French government decided that solar energy was too expensive and stopped funding Mouche's research. In 1918, the Polish chemist Jan Kojokralaski discovered a method for enhancing the content of high-quality crystals. The development of C-C technology began in the second half of the 20th century. In 1953, the American chemist Dan Trivich first made a theoretical calculation of the performance of solar cells for materials with different band gaps. The actual evolution of solar cells, as we know it today, began at Bell Laboratories in the United States. In 1999, worldwide installed photovoltaic power exceeded 1 GWP. By renewing the public interest in solar energy since about 2000, environmental issues and economic issues have become more important in public discussion. Since 2000, the POV market has therefore transformed from a regional market to a global market, as discussed in Chapter 2, Germany has pursued a progressive feed-in tariff policy, leading to a larger national solar market and industry [19]. For 200 years, the Chinese government has been investing heavily in its PV industry. As a result, China has been an influential PV module manufacturer for several years. In 2012, global solar power surpassed the magic barrier of 100 gig watts [1 17]. Between 1999 and 2012, installed PV capacity increased by 100 factors. In other words, over the past 13 years, the average annual increase in installed PV capacity was about 40%.	en_US
dc.description.abstract	Organic photovoltaic has been developed for more than 30 years, however, within the last decade the research field gained considerable in momentum. The amount of solar energy lighting up Earth's land mass every year is nearly 3,000 times the total amount of annual human energy use. But to compete with energy from fossil fuels, photovoltaic devices must convert sunlight to electricity with a certain measure of efficiency. For polymer-based organic photovoltaic cells, which are far less expensive to manufacture than silicon-based solar cells, scientists have long believed that the key to high efficiencies rests in the purity of the polymer/organic cell's two domains -- acceptor and donor. The basic principle of organic solar cells is to place layer(s) of organic electronic material between two metallic conductors of two different work functions. This difference of work function sets up an electric field within the organic layer(s) which when absorbs light, causes the excited electrons to be pushed towards positive electrode and holes towards negative electrode. This thesis has been based on an optimized two layer organic solar cell which aims to increase the photon absorption by increasing the interface area between donor and acceptor levels. This report summarizes the latest advances in the interfacial layers for bi-layer OSCs (including bulk hetero-junction photovoltaic cells. Finally, a brief summary and some perspectives about the current challenges and opportunities have been presented about this interesting area of research.	en_US
