In case of bulk silicon solar cells, Yablonovitch et al. proposed the Yablonovitch limit which places a 4n 2-factor upper bound on rise in the optical path length required for efficient light absorption. This improvement factor serves as the benchmark for measuring how well a solar cell can absorb light. We can achieve solar cells that are optically …
In conventional solar cells, relatively thick absorbers have been used to ensure that most incident photons are absorbed in a single pass through the cell. However, the effective optical path length can be increased by light-trapping strategies [8, 9], so that the same values of photogenerated currents and efficiencies can be preserved in much ...
For example, as shown in Fig. 9 in ultra-thin solar cells (Vanecek et al. 2011), a nanostructure thin film is prepared, and the incident light is continuously refracted and reflected in the semiconductor layer, increasing the optical path and achieving high-efficiency light absorption with small film thickness. This structure is also favorable for the collection of …

Solar cells can operate at increased efficiencies under higher solar concentration and replacing solar cells with optical devices to capture light is an effective method of decreasing the cost of a system without compromising the amount of solar energy absorbed. However, CPV systems are still in a stage of development where new designs, methods and …
The solar cell device''s optical enhancement depends on the size, shape, and position of the plasmonic and metal-dielectric core-shell NPs. So it is highly demanded to absorb a broad spectrum of wavelength in the active layer to increase the generation rate of carriers. In the electrical part, there are two core mechanisms involved. Firstly, the collection method of …

Transparent patch antennas are microstrip patch antennas that have a certain level of optical transparency. Highly transparent patch antennas are potentially suitable for integration with solar panels of small satellites, which are becoming increasingly important in space exploration.

SiO 2-based antireflection (AR) films can obviously improve the transmittance of the glass cover on the solar cells.Nevertheless, it''s still challenging to fabricate SiO 2 films in a facile way with great antireflective properties, high hardness and good weather resistance to ensure their long-term use in outdoor environments. To solve this problem, a double-layer …
The optical path-length of a c-Si solar cell largely depends on the reflection distribution of the front/rear surfaces and the reflectivity of rear surface . In commonly used cell designs, the reflection distribution is maximised by either a regular array of inverted pyramids or a random array of pyramidal features, both of which can provide near Lambertian scattering [ 8, …
