In-depth assessments of cutting-edge solar cell technologies, emerging materials, loss mechanisms, and performance enhancement techniques are presented in this article. The study covers silicon (Si) and group III–V materials, lead halide perovskites, sustainable chalcogenides, organic photovoltaics, and dye-sensitized solar cells.
A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light.. Individual solar cell devices are often the electrical
Besides electrical-responsive chromic materials, thermal-responsive chromic materials such as VO 2, hydrogels, and LCs have been widely used as the chromic unit to combine with solar cells for devising SPWs because they can automatically modulate solar energy according to the change of ambient temperature for giving the SPWs energy-saving effect

These cells are more effective because they employ a variety of absorber materials with different bandgaps, allowing them to effectively absorb a wider range of sunlight wavelengths and so enhance both spectrum utilization and overall efficiency.
Today’s solar cells – which are typically silicon-based – can convert an average of around 22% of the sunshine they absorb into power. More efficient solar cells mean each solar panel can generate more electricity, saving on materials and the land needed. Manufacturing silicon solar cells is also an energy-intensive process.
The power conversion efficiency of a solar cell is a parameter that quantifies the proportion of incident power converted into electricity. The Shockley-Queisser (SQ) model sets an upper limit on the conversion efficiency for a single-gap cell.
This conversion process allows for optimal exploitation of solar radiation, leading to higher overall efficiency. Also, because heat is dissipated to a working fluid, the operating temperature of PV cells tends to decrease, which results in higher electrical performance.
Furthermore, Multiple researchers have conducted reviews on diverse cooling technologies that enhance the performance of solar cells. For instance, a review paper by Ghadikolaei provides an overview of various cooling technologies and their impact on the performance of commercially available photovoltaic (PV) cells (Anon (2002)).
Throughout the years, the evolution of solar cells has marked numerous significant milestones, reflecting an unwavering commitment to enhancing efficiency and affordability. It began in the early days with the introduction of crystalline silicon cells and progressed to thin-film technology.
