Abstract | An improved understanding of photovoltaic and electrical properties of poly-3(hexylthiophene) (P3HT) - single walled carbon nanotubes (SWNT) bulk heterojunction solar cells was achieved by studying light and dark characteristics current density and voltage (J-V) characteristics of devices fabricated with different blend ratios. The SWNTs inside P3HT were found to be in the form of ropes of diameters up to 30 nm. The open circuit voltage (V) of the solar cell to observed to reduce - from 0.45 V to 0.017 V - with increase in SWNT concentration - from 0 wt% to 2 wt%. The Fill Factor (FF) and short circuit current density (J) were found to be fairly constant at around 2 μA $cm^{−2}.$ The comparative analysis of the dark J-V characteristics of the devices characterised helped isolate the current density components J and J, due to SWNT and P3HT respectively. Electron affinity values of 3.13 eV and 3.58 eV were calculated for P3HT and SWNTs. |

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.
