A sizable fraction of solar radiation cannot be converted into electricity by photovoltaics (PVs) because of (1) sub-bandgap photons, and (2) thermalization losses [1].This claim is especially valid for the single-junction cells that dominate current solar cell technology, and is less pronounced but still germane for today''s best commercial multi-junction (MJ) cells.

Temperature plays a crucial role in shaping the electrical characteristics of solar cells, impacting both voltage and current output. Regarding voltage, the open-circuit voltage (Voc) diminishes with rising temperatures, influencing the maximum power point voltage (Vmpp).
Seasonal changes play a pivotal role in influencing solar cell temperature. During winter in cold climates, solar cells may encounter reduced efficiency due to the colder temperatures (Salamah et al., 2022). Cold weather can affect the performance of solar cells by altering the behavior of charge carriers and increasing resistive losses.
