Summary: Silicon quantum dots have been used to enhance the efficiency of solar cells. In this study, Phenylacetylene-capped silicon quantum dots were fabricated and applied as luminescent downshifting material on polycrystalline silicon solar cells. The coated solar cell samples showed an increase in short circuit current and power output, with a further enhancement achieved by full encapsulation of the samples. The reduction in specular and diffuse reflectance indicates the potential of Phenylacetylene-capped silicon quantum dots as luminescent downshifting material for improving power conversion efficiency of solar cells.

Summary: A novel composite downshifting nanomaterial composed of YVO4:Eu3+,Bi3+ nanoparticles and Ag nanoparticles was introduced onto industrial silicon heterojunction (SHJ) solar cells to achieve UV shielding. The composite structure showed significantly enhanced emission intensities due to the localized surface plasmon resonance (LSPR) effect, and reduced the degradation of power conversion efficiency (PCE) under UV irradiation. The experimental results demonstrated its excellent potential for enhancing the UV light stability of solar cells.

Summary: Inefficient passivation of phosphorous diffused emitter is one of the limiting factors contributing to lower efficiency in advanced p-type silicon solar cells. Stack of SiO2 and SiNX with the former as an intermediate layer beneath SiNX provides better emitter passivation in comparison to SiNX film alone. Spray SiO2/SiNX is shown to be a viable alternative to thermal SiO2/SiNX stack for emitter passivation in silicon solar cells.

Summary: This study investigates the potential of ultra-thin HfO2 films grown by atomic layer deposition for passivating contacts to silicon. It specifically focuses on variations in film thickness and post-deposition annealing temperature. The results show that 2.2 nm thick films annealed at 475 degrees C exhibit the highest passivation quality. The effective work function of the films also decreases with decreasing thickness. A post-deposition annealing process reduces the effective work function further. The study also examines the contact resistivity in a passivating contact structure utilizing HfO2 and finds a temperature dependence on the annealing process. The lowest resistance is achieved below 375 degrees C.
