Enhanced carrier extraction of a-Si/c-Si solar cells by nanopillar-induced optical modulation.
We demonstrate improved short-wavelength internal quantum efficiency (IQE) of a-Si/c-Si heterojunction (HJ) solar cells with a surface nanopillar (NP) array via simulation. The gain in IQE is attributed to the light-field modulation caused by the cavity resonance inside the NPs, in which the light energy is effectively localized within the c-Si bulk rather than the a-Si layer. The average IQE i...
متن کاملPeriodically Aligned Si Nanopillar Arrays as Efficient Antireflection Layers for Solar Cell Applications
Periodically aligned Si nanopillar (PASiNP) arrays were fabricated on Si substrate via a silver-catalyzed chemical etching process using the diameter-reduced polystyrene spheres as mask. The typical sub-wavelength structure of PASiNP arrays had excellent antireflection property with a low reflection loss of 2.84% for incident light within the wavelength range of 200-1,000 nm. The solar cell inc...
متن کاملA High-Efficiency Si Nanowire Array/Perovskite Hybrid Solar Cell
A low-cost Si nanowire array/perovskite hybrid solar cell is proposed and simulated. The solar cell consists of a Si p-i-n nanowire array filled with CH3NH3PbI3, in which both the nanowires and perovskite absorb the incident light while the nanowires act as the channels for transporting photo-generated electrons and holes. The hybrid structure has a high absorption efficiency in a broad wavelen...
متن کاملStacked GaAsSbN-capped InAs/GaAs quantum dots for enhanced solar cell efficiency
Different approaches have arisen aiming to exceed the Shockley-Queisser efficiency limit of solar cells. Particularly, stacking QD layers allows exploiting their unique properties, not only for intermediate-band solar cells or multiple exciton generation, but also for tandem cells in which the tunability of QD properties through the capping layer (CL) could be very useful. On one hand, GaAsSb C...
متن کاملDesigner Ge/Si composite quantum dots with enhanced thermoelectric properties.
An otherwise random, self-assembly of Ge/Si composite quantum dots (CQDs) on Si was controlled by inserting a layer of Si, sub-dot stacks, and post-annealing to produce micron-scale-thick QD layers with desired QD morphology, interface density, and composition distribution. A heterostructure consisting of a deliberate insertion of Si between Ge sub-dots is shown to improve the epitaxial coheren...
