| Abstract | Emcore is presently qualifying the fourth generation triple junction (3J) solar cell under the Air Force ManTech program. This cell referred to as the ZTJ, is designed to achieve 30% conversion efficiency under 1 sun AM0 illumination. In addition a companion cell with a monolithically integrated protection diode referred to as the ZTJM is under qualification at Emcore with a target AM0 efficiency of 29.5%. We present performance results of each of these 3J cells from pilot line production. In addition, modeling results of various 3J solar cell designs are discussed to motivate the use of a new 3J architecture that relieves the constraint of an active germanium subcell. This new architecture known as inverted metamorphic multi-junction (IMM) allows one to more easily realize the optimum set of band gaps in monolithically connected n-junction solar cell devices. Finally, recent performance results of our fifth generation 3J cell known as the 3J IMM are reported here. |

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.
