This research aims to present a state-of-the-art cleaning technology solution that effectively overcomes the dust accumulation issue for conventional photovoltaic systems. Although continuous innovations and advanced developments within renewable energy technologies have shown steady improvements over the past years, the dust accumulation issue remains one of the main factors hindering their efficiency and degradation rate. By harvesting abundant solar thermal energy, the presented self-cleaning system uses a unique thermomechanical property of Shape Memory Alloys to operate a solar-based thermomechanical actuator. Therefore, this study carries out different numerical and experimental validation tests to highlight the promising practicability of the developed self-cleaning system from thermal and mechanical perspectives. The results showed that the system has a life expectancy of over 20 years, which is closely equivalent to the life expectancy of conventional photovoltaic modules while operating under actual weather conditions in Dammam city. Additionally, the thermal to mechanical energy conversion efficiency reached 19.15% while providing average cleaning effectiveness of about 95%. The presented outcomes of this study add to the body of knowledge an innovative methodology for a unique solar-based self-cleaning system aimed toward smart and modern photovoltaic applications.

“…SMAs can play important roles because they have several interesting physical and mechanical excellent properties, such as good corrosion resistance, high fatigue life, high damping capacity, and good flexibility to produce possible shape and size. These properties are related to the main two superior behaviors which are superelasticity (SE) and shape memory effect (SME) [6,51,52]. Among all types of SMAs, NiTi-based SMA has more technological applications especially in biomedical applications because it has excellent mechanical properties and high biocompatibility [53].…”

“…Besides, shape memory is an ability of SMAs that has two types, that classified into Superelasticity (SE) and shape memory effect (SME) [1][2][3]. Thus, these behaviors have made SMAs be used in wide application areas such as the automotive [4,5], aerospace [6,7], engineering [8], industrial [9], and medical field such as dental, orthopedics, vascular, and neurological [10]. Also, SMAs have two different phases which are known as austenite and martensite with various physical characteristics and crystal structures [11][12][13][14][15][16][17].…”

ARTICLE INFOShape memory alloys have the thermoelastic phase transformation, known as shape memory characteristics, which make them be used in wide technological applications compared to other alloys. Ni-Ti based SMAs compared to the other families have more applications especially in the biomedical field since they have high biocompatibility, high strain recovery, flexibility, and antirust. In this work, the studies conducted for NiTiCu SMAs were reviewed. Additionally, different manufacturing techniques used by researchers have been explained. Different characteristics of the alloys have been clarified and compared with some other families.
