| Abstract | Polycrystalline silicon still guarantees its application on solar cells as important market product until year 2050. Due to the increase of photovoltaic industry needing, technologies to produce low cost silicon will be needed. The metallurgical grade silicon (Si-GM) has been used to produce Si substrates by the atmospheric plasma thermal spray (APTS) which has the advantages of a low cost and fast process. The aim of this work is to characterize the APTS Si sheet microstructure and chemical composition to promote its technology association for low cost solar cell substrate production. The raw material and APTS Si sheet were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and Raman spectroscopy. The results showed a structural mixed silicon sheet with different levels of crystalline fraction, amorphous structures contribution, phase transitions regions, crystallite size distribution as well as a mainly silicon oxides covered surface. |

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.
