| Abstract | We made two photovoltaic devices using blend of Safranine T dye in a thin film of polyvinyl alcohol mixed with solid electrolyte made by PEO and $LiClO_{4},$ placed between two electrodes, resulting photo electrochemical cell (PEC) structure. One of the cells made of two ITO coated glass plates as electrodes and the other with ITO and Silver. The current voltage relation of the cells has been measured in the dark. Detail analysis of the dark I-V curve shows two distinct regions below and above certain voltage for the second cell unlike to first cell, which has only one region. I- V curve for the cells indicates trap charge limited (TCL) conduction through exponentially distributed traps. Characteristic trap energy (Et) has been calculated for both the cells. Use of dissimilar electrodes increases efficiency up to one order in magnitude than the other. From photovoltaic current growth nature we discussed the charge transport process through these materials using concept of dispersive transport model. |

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.
