| Abstract | Organic photovoltaics are being explored for powering electronic devices by harvesting the sun's energy or indoor lighting. Such solar cells have shown promise as they can be deposited on thin flexible foils that enable flexibility of integration within products while keeping the weight light. Several R&D efforts are underway in creating improved organic solar cells in terms of their efficiency and other performance metrics. One such is the FACESS project (“Flexible Autonomous Cost Efficient Energy Source and Storage”), funded under the 7th Framework Programme of the European Commission. The main goal is to develop economically viable solar cells on large scale for mass production to achieve the power conversion efficiency (PCE) up to 2.5% thus producing 250 mW under AM1.5 illumination. This requires selection, modification and up-scaling of suitable solar cell materials, effective patterning technologies, development of the printing processes and improved encapsulation technologies. This development will be done keeping all the time the application, the potential and the required performance in mind. The development and experimental results of roll-to-roll techniques such as wet chemical etching of an anode electrode, gravure printing of PEDOT:PSS and the P3HT:PCBM photoactive layer and gas barrier lamination of the printed modules will be presented in detail. The performance status for lab-scale printed solar cells is currently 2.4% of PCE under AM1.5 illumination. In addition the major technological challenges and solutions for roll-to-roll manufacturing will be summarised. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
