| Abstract | The high-crystallinity, large-grain and full-coverage CH3NH3PbI3 thin films are successfully prepared by converting the PbI2·dimethyl sulphoxide (DMSO) complex thin films at the optimum annealing temperature and time of 140°C and 10 min in the glove box with the relative humidity of 10–15%. The influence of the annealing temperature and time on the crystallinity, surface morphology, optical absorption of CH3NH3PbI3 thin films is systematically investigated and the photovoltaic performance of the corresponding TiO2 nanorod array perovskite solar cells is evaluated. The results reveal that the crystallinity of CH3NH3PbI3 thin films can be improved and their grain sizes gradually increase from 200–300 to 300–500 and 500–800 nm with the increase of the annealing temperature from 100 to 120 and 140°C. The TiO2 nanorod array perovskite solar cells with the optimum annealing temperature and time of 140°C and 10 min exhibit the best photoelectric conversion efficiency (PCE) of 16.11% and the average PCE of 15.62 ± 0.49%. |

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.
