Abstract
With the surge in population and adopting technology to lead life, global energy demand has increased over the years with increasing global warming. Renewable energy sources are paramount for eco-friendly, sustainable as well as efficient energy generation. Solar energy is most feasible due to its abundance in India together with push from government for increasing the solar PV panel deployment. Silicon based solar cells although are more established have
issues to meet targets in large scale production. Perovskite solar cells (PSCs) with extraordinary optoelectronic properties and record power conversion efficiencies are at the forefront of emerging photovoltaic technologies. Inverted planar (p-i-n) PSCs are particularly under the recent spotlight owing to their straightforward low-temperature fabrication and compatibility with flexible substrates together with easier integrability in existing silicon cells in tandem configuration. Role of interface layers and interface defects limiting the performance of the p-i-n perovskite solar cell devices and approaches to make it more stable and efficient will be discussed in this talk.
