| Abstract | In this paper we report the effect of scattering and plasmon enhancement on the energy conversion efficiency of silver nanoparticles (nps) incorporated azo/si heterojunction solar cells. The studied solar cell structure consists of a 240 nm of heavily al doped zno (azo) layer with ag nps on an n-type si. Therefore, azo layer is considered as a transparent current spreading layer with enhanced conductivity as well as rectifying junction with a si. Computer simulation using fdtd method was carried out to explore the effect of ag nps at different positions, densities and sizes in an azo layer. Also, the results were compared to the fabricated devices. To analyze the scattering and plasmon resonance effect, the energy distribution and current generation from azo to si layer was calculated in a spectral range of 400 nm to 1100 nm using standard solar spectrum with 100 $mw/cm^{2}$ of power density. The calculations were performed, introducing three variables, which are 10-150 nm of nanoparticles sizes, 5-45 % of surface loading amount, and 0-100 nm of nanoparticle position from the junction. This study reveals that there is a certain position (20-40 nm from the azo/si junction) of nanoparticles inside the structure where the energy conversion efficiency reaches to its maximum. These results were well matched with the fabricated solar cells using same structures. The best performance of azo /si heterojunction solar cell was shown to have 0.36 v of Voc, 28.3 $ma/cm^{2}$ of jsc and an efficiency of 5.91 % when the ag np layer were located at 30 nm from the junction. This study will benefit to the design of surface plasmon enhanced solar cell structure using metallic nanoparticles to maximize the surface plasmon effect and to minimize scattering losses. |

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.
