Solar energy is the ultimate renewable zero emission energy source. Solar energy technology which is dominated by the crystalline silicon has not found widespread acceptance due to size, weight, aesthetics, cost and installation of solar panels. On the other hand, polymer solar cells being light weight, inexpensive, colorful and capable to be fabricated into large area flexible devices by roll to roll processes, portend potential for large scale non-grid and grid power generation applications. Polymer solar cells would reduce the need for petroleum and natural gas for power generation; therefore, the use of cells would slow down the disappearance of non-renewable resources and promote sustainability. In spite of these facts, polymer solar cells are not covered in current curricula and textbooks of Materials Science and Engineering. The present article intends to provide the remedy to this situation and exhaustively discusses materials, mechanisms and applications in the development of highly efficient polymer solar cells (PSCs).</p>10aBulk heterojunction polymer solar cells10aElectron acceptors10aElectron donors10aInverted and Tandem solar cells10aRoll to roll processing10aSolar cell efficiency1 aSingh, Ram, Prakash1 aKushwaha, Omkar, Singh  uhttps://library.ncl.res.in/content/polymer-solar-cells-001945nas a2200217   4500008004100000022001400041245003700055210003600092260012400128300001200252490000800264520123000272653002401502653002201526653001901548653001501567653002401582100002401606700002701630856007001657       2013                        eng d  a1022-136000aPolymer solar cells: an overview0 aPolymer solar cells an overview  aBOSCHSTRASSE 12, D-69469 WEINHEIM, GERMANYbTribhuvan Univ; Kathmandu Univ; Univ Rouen; Int Union Pure & Appl ChemcMAY  a128-1490 v3273 a<p>Polymer Solar cells being flexible, light weight, inexpensive, colorful and large area devices, portend potential for large scale grid power generation. The first major breakthrough in organic solar cell performance came in 1986 when Tang discovered that much higher efficiencies about 1% can be attained when electron donor (D) and electron acceptor (A) are brought together in one cell. With the discovery of photo induced electron transfer from a conjugated polymer to fullerene molecules in 1992, the bulk heterojunction (BHJ) polymer solar cell has become the most successful device structure developed in the field till date. Poly(3-hexyl thiophene) (P3HT) has been the subject of intensive investigations upto 2008 yielding power conversion efficiencies (PCEs) around 5-6%. OPV technology has grown during the past decade with cell efficiencies quadrupling. As alternative route of higher performance, two or more single cells can be combined in tandem structure. The most efficient tandem organic solar cell reported by Yang Yang's group has 8.62% power conversion efficiency (PCE) which has been further improved with an NREL - certified PCE of 10.6%. An overview of the above will be presented in this paper.</p>10abulk heterojunction10aelectron acceptor10aelectron donor10afullerenes10apolymer solar cells1 aSingh, Ram, Prakash1 aKushwaha, Omkar, Singh  uhttps://library.ncl.res.in/content/polymer-solar-cells-overview-0
