In this work, a temperature-dependent analytical model is developed to investigate the temperature effect of perovskite solar cells based on diffusion-drift numerical modeling. It was found that the built-in electrical field and minority carrier concentration are closely corrected with temperature, explaining the thermal induced PCE variation.
Perovskite solar cells (PSCs) have promised high-efficiency and low-cost solar-to-electrical conversion that now go outdoors for practical applications; however, the elevated outdoor temperature remarkably affects the photovoltaic efficiency. To date, there has been little work about understanding the temperature sensitivity of PSCs.
Temperature is a crucial factor influencing both the preparation and performance of perovskite solar cells. The annealing temperature exerts a pronounced impact on the device structure, while the operational temperature influences carrier transport, perovskite band gap, and interface properties.
The device was annealed at different temperatures, and the device had the best performance at 300 °C . Luo and Liu et al. , when preparing perovskite/silicon-laminated solar cells, both annealed at 200 °C for 10 min to recover sputtering damage before preparing perovskite top cells. 3.
Optimal deposition occurs near room temperature, as excessive temperatures cause incomplete reactions or inhibited conversion. The form and chemistry of perovskite varies depending on the hole-transport layer, with MeO-2PACz consistently producing better efficiencies.
Average performance parameters of perovskite devices with different heat temperatures are shown in Fig. 5 f. The heat time is slightly distinction at different heat temperatures (heated for 70 min at 25 °C, 85 °C, 100 °C, and 150 °C, 15 min at 200 °C and 3 min at 250 °C).
