| Abstract | CuSbS$_{2}$ thin film solar cell with 2.99 % efficiency has been demonstrated by using the Cd-free GaN and In$_{0.15}$Ga$_{0.85}$N as n-type semiconductor bilayer. CuSbS$_{2}$ films on the TiN-coated Mo/glass substrates were made by co-sputtering technique at 300 °C with a cermet target of (Cu + Sb$_{2}$S$_{3}$) operated at 50–60 W and a metal target of Cu at 2 W, followed by thermal annealing at 350–450 °C for 1 h. The effects of processing conditions on the growth behavior, microstructural characteristics, and electrical properties of CuSbS$_{2}$ films had been investigated. Solar cell devices were fabricated by depositing ~50 nm GaN and ~300 nm In$_{0.15}$Ga$_{0.85}$N layers with low temperature radio-frequency (RF) sputtering method, followed by RF sputtering 300–400 nm indium-tin oxide for front contact and pasting silver glue for electric contacts. The CuSbS$_{2}$ thin film sputtered at 55 W had a [Cu]/[Sb] ratio of 0.80 with co-exists of the Sb$_{2}$S$_{3}$, and had a hole concentration of 1.41 × 10$^{18}$ cm$^{−3}$, an electrical conductivity 0.1 S cm$^{−1}$, and mobility of 13 cm$^{2}$ V$^{−1}$ s$^{−1}$. The efficiency of the solar cell device had a 3.83-fold increase if the p-CuSbS$_{2}$/CdS/n-ZnO system had its conventionally designed CdS/n-type ZnO layer replaced by n-type GaN/In$_{0.15}$Ga$_{0.85}$N bilayer. |

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.
