Abstract
Over the years, there has been a rising interest in the use of photovoltaic (PV) technology in building-integrated photovoltaics (BIPVs) due to its inherent advantages in energy generation. Perovskite solar cells (PSCs) are emerging photovoltaics (PVs) with tunable bandgap, high absorption coefficient, and high charge carrier mobility,resulting in high power conversion efficiency (PCE). PSCs can be fabricated as semi- transparent (ST) devices, which are beneficial in a lot of innovative applications such as BIPVs. This work proposes an energy harvesting system for a bus stop shelterlocated in Astana, Kazakhstan, as an example to demonstrate the potential performance of using perovskite solar cell modules (PSCMs) in BIPVs. The system includes maximum power point tracking (MPPT) and charge controllers, which can optimize energy conversion from sunlight to electrical energy for charging the batteries so that the electronics of the bus stop shelter can still be powered during low illumination. The rechargeable batteries store the surplus energy generated from the PSCMs. The two most representative scenarios for energy generation from PSCMs,May (best-case) and December (worst-case), are considered.
