AI Customer ServiceThe simulations results are supported by outdoor experiments showing that, under partial shading conditions, a PV module made with IBC cells with a BDV of 3 V produced an average of 4.2% more energy than a PV module with FBC solar cells with BDVs larger than 10 V and 6 bypass diodes.
As the cell area is 20% shaded, a power loss of 11.6% is recorded. However, further shading 40% of the PV cell causes a rapid drop in power of 30.4%. The large variance is recorded during 40% shading, where the module power ranges from 364.822 to 253.5546 W. After shading 60% and 80% shading, the power loss stabilizes to approximately 36.18%.
In this work, we explain that improving the reverse characteristics of IBC solar cells is another promising approach to boosting the performance of PV modules by increasing the shading tolerance and limiting the operating temperature of shaded solar cells.
In particular, the poor shading tolerance of conventional PV modules strongly limits the energy performance of urban PV systems. In this work, we analyze how interdigitated back-contact solar cells with low-breakdown voltages can help improve the shading tolerance of PV modules.
This occurs due to a sudden drop in photo-generated current. It is very clear from the experiment that the shading percentage from 40 to 60% is a probable partial shading condition when exhibited on a single PV, will cause maximum damage to the PV cell.
Due to variable solar radiation and ambient temperature, the shading may impact the efficiency and performance of photovoltaic modules Under fielded conditions. Hence, during outdoor testing, the impact of shading is analysed under various shading scenarios. After that, possibilities for the development of hotspots are analysed.
