“…To incorporate the activator ions into the host matrixes, the powdered raw materials are heated above their melting points. The advantages of this process include obtaining homogeneous mixing of metal ions at the molecular level, obtaining extremely tiny particles with a high packing density, and offering better crystalline structures with high purity. − …”

Insufficient utilization of the solar spectrum in commonly employed solar cells, stemming from a spectral mismatch between the solar spectrum and the solar cell’s band gap, poses a barrier to enhancing solar cell efficiency. To overcome this challenge, downconverting silicate phosphors are employed in solar cells to capture the infrared spectrum of sunlight, thereby augmenting solar cell efficiency. Downconversion/downshifting involves in converting high-energy photons into one or two near-infrared (NIR) photons. Remarkably, silicate-based downconverting phosphors enhance solar cell sensitization, light scattering, antireflectivity, and stability. This review delves into the various energy transfer mechanisms utilized in silicate phosphors. The key aspects covered in this review encompass the development of silicate phosphors that emit NIR light and their synthesis process. The working principle of the solar cell and its parameters are discussed. The impacts of silicate phosphor size, coverage, volume concentration, and arrangement on solar cell performance are also explored. Furthermore, the study addresses several intriguing approaches for developing innovative silicate phosphors to enhance solar cell performance.
