“…As per the current standard, the temperature range is set at −40to 85°C, with a maximum ramp rate of 100°C/h. These testing conditions represent the failures primarily in cell components (such as finger breakages and cell cracks) during standard TC testing 200,201 . A desert‐recommended temperature cycle called Desert TC (DTC) replacing the previous −40°C and 85°C cycle (ramp rate of 100°C/h) with a −20°C and 105°C cycle with a maximum ramp rate of 200°C/h, and a minimum dwell period of 10 min.…”

Desert regions have emerged as ideal places for GW utility‐scale photovoltaic (PV) module installations because of their ultra‐large spaces, abundance of high‐irradiance sunshine hours, and clear sky. However, the harsh desert climate presents challenges to the reliability and bankability of PV modules. This review provides an in‐depth understanding of the unique desert parameters impact, desert‐induced degradation modes, status, and required properties of the bill of materials (BOMs) and suggestions for the development of desert standards. The review reveals that the climatic conditions in the desert are considerably harsher than those in the moderate climate. The main degradation mechanisms caused by the desert are ultraviolet (UV)‐induced discoloration, thermomechanical flaws of interconnects, and glass abrasion (because of soiling). The development of desert modules may necessitate the use of new‐generation modules with low‐temperature coefficients, high efficiency, high bifaciality, stability under UV light, and elevated temperatures. For the desert module application, options include advanced back sheets and encapsulants that are thermally and UV stable, free of acetic acid groups, and have a low water vapor transfer rate. The degradation modes induced by desert climate are not sufficiently addressed by the present environmental and safety standards through accelerated aging tests. As a result, this article provides a summary of current standards and recommends creating a new testing proposal called the “Hot Desert Test Cycle (HDTC)” sequence that is specific to the desert climate. This comprehensive review catalyzes the PV community to explore novel designs and develop desert PV modules while adhering to localized standards.
