Two and Three- Dimensional Perovskite Physics and devices<\/strong><\/h2>\n<p>Perovskite solar cells have generated significant interest ever since their discovery less than a decade ago. Since then there have been remarkable increases in device performances and the best devices now show up to 22 % PCE. However, while this is really interesting, there are severe stability challenges that need to be addressed. In this regards, 2-D perovskites have emerged as an interesting alternative that are more stable that the 3-d perovskites. However, like ost things there is a trade-off, and PCE suffers when stability increases. We are fabricating 2-D perovskites to explore the parameter space, understand the underlying exitonic physics through optical spectroscopy, as well as experiment with novel hold transport layers to increase stability as well as photovoltaic efficiency of devices.<\/p>\n<h2><strong>2. Optically and electrically pumped Two-dimensional Quantum light sources<\/strong><\/h2>\n<p>We are interested in developing on-demand single photon sources for quantum photonic circuits. We are currently investigating the use of Molybdenum disulphide in novel photonic architectures as well as doping schemes. Future work will focus on the development of second order correalation setups for single photon detection and validation, as well as optimization towards single photon generation.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignright  wp-image-305\" src=\"http:\/\/web.lums.edu.pk\/~fmod\/wp-content\/uploads\/2023\/10\/Mos2-work.png\" alt=\"\" width=\"442\" height=\"324\" srcset=\"https:\/\/web.lums.edu.pk\/~fmod\/wp-content\/uploads\/2023\/10\/Mos2-work.png 2832w, https:\/\/web.lums.edu.pk\/~fmod\/wp-content\/uploads\/2023\/10\/Mos2-work-300x220.png 300w, https:\/\/web.lums.edu.pk\/~fmod\/wp-content\/uploads\/2023\/10\/Mos2-work-1024x751.png 1024w, https:\/\/web.lums.edu.pk\/~fmod\/wp-content\/uploads\/2023\/10\/Mos2-work-768x563.png 768w, https:\/\/web.lums.edu.pk\/~fmod\/wp-content\/uploads\/2023\/10\/Mos2-work-1536x1126.png 1536w, https:\/\/web.lums.edu.pk\/~fmod\/wp-content\/uploads\/2023\/10\/Mos2-work-2048x1501.png 2048w\" sizes=\"(max-width: 442px) 100vw, 442px\" \/><\/p>\n<h2>\u00a0<\/h2>\n<h2>\u00a0<\/h2>\n<h2>\u00a0<\/h2>\n<h2>\u00a0<\/h2>\n<h2>\u00a0<\/h2>\n<h2>\u00a0<\/h2>\n<h2>\u00a0<\/h2>\n<h2><strong>3.
