Joseph J. Loferski
Joseph John Loferski (August 7, 1925 – January 20, 1997) was an American physicist and a professor of engineering at Brown University. ''The New York Times'' called him "a pioneer in the development of solar cells". During his long and successful career he focused primarily on photovoltaic cells and their ability to convert the energy in light to electricity. Loferski also wrote and spoke extensively on the physics of semiconductor materials such as silicon, and methods of improving the efficiency of photovoltaic cells. Loferski's work and that of other early researchers proved that semiconductor devices could produce commercially viable, pollution-free electricity. Early life and education Joseph J. Loferski was born in Hudson, Pennsylvania, the son of a coal miner. He went to college at University of Scranton and attended the University of Pennsylvania, earning his master's degree in 1949 and his doctorate in 1953. At RCA Laboratories in Princeton, New Jersey, Loferski an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Semiconductor
A semiconductor is a material which has an electrical resistivity and conductivity, electrical conductivity value falling between that of a electrical conductor, conductor, such as copper, and an insulator (electricity), insulator, such as glass. Its electrical resistivity and conductivity, resistivity falls as its temperature rises; metals behave in the opposite way. Its conducting properties may be altered in useful ways by introducing impurities ("doping (semiconductor), doping") into the crystal structure. When two differently doped regions exist in the same crystal, a semiconductor junction is created. The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors, and most modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called "metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Scranton
The University of Scranton is a private Jesuit university in Scranton, Pennsylvania. It was founded in 1888 by William O'Hara, the first Bishop of Scranton, as St. Thomas College. In 1938, the college was elevated to university status and took the name The University of Scranton. The institution was operated by the Diocese of Scranton from its founding until 1897. While the Diocese of Scranton retained ownership of the university, it was administered by the Lasallian Christian Brothers from 1888 to 1942. In 1942, the Society of Jesus took ownership and control of the university. During the 1960s, the university became an independent institution under a lay board of trustees. The university is composed of three colleges: The College of Arts and Sciences, The Kania School of Management, and The Panuska College of Professional Studies; all contain both undergraduate and graduate programs. Previously, the university had a College of Graduate and Continuing Education, which has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Pennsylvania
The University of Pennsylvania (also known as Penn or UPenn) is a private research university in Philadelphia. It is the fourth-oldest institution of higher education in the United States and is ranked among the highest-regarded universities by numerous organizations and scholars. While the university dates its founding to 1740, it was created by Benjamin Franklin and other Philadelphia citizens in 1749. It is a member of the Ivy League. The university has four undergraduate schools as well as twelve graduate and professional schools. Schools enrolling undergraduates include the College of Arts and Sciences, the School of Engineering and Applied Science, the Wharton School, and the School of Nursing. Among its highly ranked graduate schools are its law school, whose first professor wrote the first draft of the United States Constitution, its medical school, the first in North America, and Wharton, the first collegiate business school.

RCA Laboratories
The RCA Corporation was a major American electronics company, which was founded as the Radio Corporation of America in 1919. It was initially a patent trust owned by General Electric (GE), Westinghouse, AT&T Corporation and United Fruit Company. In 1932, RCA became an independent company after the partners were required to divest their ownership as part of the settlement of a government antitrust suit. An innovative and progressive company, RCA was the dominant electronics and communications firm in the United States for over five decades. RCA was at the forefront of the mushrooming radio industry in the early 1920s, as a major manufacturer of radio receivers, and the exclusive manufacturer of the first superheterodyne sets. RCA also created the first nationwide American radio network, the National Broadcasting Company (NBC). The company was also a pioneer in the introduction and development of television, both black and white and especially color television. During this peri ...

Solar Energy
Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy (including solar water heating), and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air. The large magnitude of solar energy available makes it a highly appealing source of electricity. In 2020 solar energy has been the cheapest source of Electricity.

Photovoltaic Specialists Conference
The IEEE Photovoltaic Specialists Conference (also called PVSC) is the longest running technical conference dedicated to photovoltaics, solar cells, and solar power. The first PVSC was in 1961 at the NASA headquarters in Washington DC. The number of conference areas have expanded and now include PV reliability and solar resource. The conference has also had many diverse and distinguished keynote speakers like Sarah Kurtz who won the conference's William Cherry Award in 2012. PVSC is also where the most notable breakthroughs in PV are often first announced, such as record Solar-cell efficiency, new technologies like perovskite, TOPCon, heterojunction (HJT), and tandem cells, derivation of new algorithms, and discoveries of new phenomena such as Potential-induced degradation and light and elevated temperature induced degradation (LeTID).

European Space Research And Technology Centre
The European Space Research and Technology Centre (ESTEC) is the European Space Agency's main technology development and test centre for spacecraft and space technology. It is situated in Noordwijk, South Holland, in the western Netherlands, although several kilometers off the village but immediately linked to the most Northern district of the nearby town Katwijk. At ESTEC, about 2500 engineers, technicians and scientists work hands-on with mission design, spacecraft and space technology.

Brown University Faculty
Brown is a color. It can be considered a composite color, but it is mainly a darker shade of orange. In the CMYK color model used in printing or painting, brown is usually made by combining the colors orange and black. In the RGB color model used to project colors onto television screens and computer monitors, brown combines red and green. The color brown is seen widely in nature, wood, soil, human hair color, eye color and skin pigmentation. Brown is the color of dark wood or rich soil. According to public opinion surveys in Europe and the United States, brown is the least favorite color of the public; it is often associated with plainness, the rustic, feces, and poverty. More positive associations include baking, warmth, wildlife, and the autumn. Etymology The term is from Old English , in origin for any dusky or dark shade of color. The first recorded use of ''brown'' as a color name in English was in 1000. The Common Germanic adjectives ''*brûnoz and *brûnâ'' meant b ...
