100 °C Thermal Stability of Printable Perovskite Solar Cells Using Porous Carbon Counter Electrodes

Abstract

Many efforts have been made towards improving perovskite (PVK) solar cell stability, but their thermal stability, particularly at 85 °C (IEC 61646 climate chamber tests), remains a challenge. Outdoors, the installed solar cell temperature can reach up to 85 °C, especially in desert regions, providing sufficient motivation to study the effect of temperature stress at or above this temperature (e.g., 100 °C) to confirm the commercial viability of PVK solar cells for industrial companies. In this work, a three-layer printable HTM-free CH NH PbI PVK solar cell with a mesoporous carbon back contact and UV-curable sealant was fabricated and tested for thermal stability over 1500 h at 100 °C. Interestingly, the position of the UV-curing glue was found to drastically affect the device stability. The side-sealed cells show high PCE stability and represent a large step toward commercialization of next generation organic-inorganic lead halide PVK solar cells.

“…Water can be split, through external energy like photon etc, for the generation of hydrogen and oxygen which are eventually used as the fuels in polymer electrolyte membrane fuel cells. [1][2][3] Similarly, the requirement of electrostatic separator, electrocatalysts for oxidation and reduction processes, and the stability of the electrolytes are key issues in metal-air batteries. [10][11][12] However, the requirement of an external energy for the water splitting along with a catalyst, durability and poisoning of the catalyst, cost effectiveness, fuel storage and its transport, etc limits such applications.…”
