Abstract | Selective emitter cell architectures are one avenue for increasing industrial solar cell efficiency. N-type cell based technology is also gaining considerable attention for the same purpose. This paper describes a novel, single step selective emitter process using atomic hydrogen to passivate boron acceptor impurities. Grid lines act as a mask to hydrogenation, which lowers the surface concentration of electrically active boron between grid lines. Using EDNA to model this complex emitter, it was shown that Jsc can be increased in the emitter by $0.94mA/cm^{2}$ with a short, low temperature atomic hydrogen treatment. A hydrogenation system has been developed, and initial experimental results on aluminum doped polycrystalline thin films shows its effectiveness. Cell fabrication is being developed to test this process on fabricated solar cells to verify theoretical results. Special processing considerations are discussed. |

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.
