| Abstract | The conversion efficiency of CIGS solar cells has reached up to a 20.3% record value [1]. It is desirable to reduce the CIGS cell cost by lowering down the manufacturing cost to enable its broader applications in the market place. Solution-based deposition offers an opportunity to fabricate CIGS thin film solar cells at a more competitive cost compared to the conventional vacuum-based process. Recently, several non-vacuum technologies, including Inkjet printing [2], electroplating [3], hydrazine [4] and nanoparticles [5], have shown great potentials to achieve comparable results with vacuum technologies. However, there are still considerable drawbacks which impede their application in a wider market field, such as the toxicity and flammability of dissolving solvents, tedious preparation process of precursor inks and fatal residuals left from organic compounds. Therefore, a versatile and controllable ink formula and an affordable deposition process are desired to fulfill the low-cost and safety requirements. In order to achieve decent conversion efficiency, the ideal chalcopyrite CIGS absorber layer should be also free of secondary phases and contaminations including binary CuSe phase, amorphous carbon and residual from solution deposition. Herein, a novel solution-based process using low cost precursors that is capable of achieving these goals is reported. |

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.
