| Abstract | A green solar cell based on a water-soluble polymer (PTEBS) and water dispersible TiO nanocrystals have been developed from all-water-solution processing. The light harvesting ability of water-soluble PTEBS were characterized by the UV-Vis absorption spectroscopy and the morphology of nanocrystalline TiO film were characterized by scanning electron microscopy (SEM). The PTEBS/TiO photovoltaic devices have showed comparable performance as those from organic-solvent based conjugated polymers (e.g. P3HT, MDMO-PPV, etc.). In addition, due to the very efficient photo-induced charge transfer from conjugated polymers to fullerenes, water soluble fullerenes are also being studied for polymer photovoltaic applications. A negatively charged fullerene derivative is being synthesized and the photovoltaic cells based on PTEBS and water-soluble fullerenes will be studied. By using water as the solvent and utilizing liquid-based processing, the cost of energy generated by this type of solar cell is ultimately expected to approach that of the current fossil fuel. Although the energy conversion efficiencies of these cells are still lower than other solvents based polymer solar cells at the current stage, the concept has shown that photovoltaic cells can be developed from all-water-solution based polymer/nanocrystal (or fullerence) composites and the prospects are high for rapid improvement in efficiencies. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
