The relentless pursuit of higher efficiency and lower production costs has led to significant breakthroughs in the field of solar cell research. Innovations in materials science, device architecture, and manufacturing processes have resulted in a diverse range of solar cell technologies, each with its unique advantages and applications. One prominent development is the emergence of third-generation solar cells, such as perovskite and organic photovoltaics, which promise greater efficiency and flexibility compared to traditional silicon-based cells. These advanced materials exhibit the potential to revolutionize the solar industry by offering improved performance in various lighting conditions and reduced environmental impact during production. Furthermore, tandem solar cells, combining multiple absorber materials, have demonstrated remarkable progress in achieving higher conversion efficiencies by effectively harnessing a broader spectrum of sunlight. Tandem solar cells can be fabricated using various materials, including perovskites, silicon, and III-V semiconductors, showcasing their adaptability to diverse applications. Integration of solar cells into building materials, such as solar windows and solar roof tiles, marks another innovative approach towards enhancing the adoption of solar energy in urban environments. These building-integrated photovoltaics not only generate electricity but also contribute to architectural aesthetics and energy-efficient design. Photogalvanics is another such promising technology which is different from photovoltaics. The photogalvanic cell is one of the prominent examples of the photoelectrochemical systems. The photogalvanic cells are based on "photogalvanic effect” which is a special case of the Becquerel effect in which the influence of light on the electrode potential is due to a photochemical process in the body of the electrolyte (as distinct from photochemical or photoelectric processes in the surface layer of the electrode, which are the basis of the original Becquerel effect).
