Estimation of Energy Generation from BIPV Samples Based on Perovskite Solar cells in Kazakhstan

Cost-effective halide perovskites can be used as a light absorber in building integrated photovoltaics (BIPVs). BIPVs are commonly in form of building facades, rooftops, shelters, windows, etc. This work aims to analyze the performance of perovskite-based photovoltaics (PVs) installed on the shelter of a bus stop for power generation in different cities in Kazakhstan. The study considers four cities located in different regions of Kazakhstan: Astana (North), Aktau (West), Almaty (South-East), and Shymkent (South). Such bus stop shelter placement grants that the bus stop shelter sides with PV will orient east, west and south. The shelter has a roof and 3 sides, namely, the East-facing, South-facing, and West-facing sides. North-faced PV generates less energy compared to the other three directions (East-facing, South-facing, and West-facing) for the northern hemisphere. The front of the bus stop is north-faced, with the bus shelter not having any north-facing PV. The roof of the bus stop is made of non-transparent perovskite solar cell modules (PSCMs), whereas the sides of the bus stop shelter are made of semi-transparent PSCMs. According to the obtained preliminary results, all cities exhibit the potential to provide sufficient solar irradiance for the designed bus stop shelter. In the southern cities, Almaty and Shymkent, the bus stop shelters can generate 882 and 906 kWh of energy from PSCMs, respectively. The same bus stop shelters located in Astana and Aktau which are in the North and West parts of Kazakhstan generate 800 and 868 kWh of energy, respectively.
