Efficient color coatings for single junction and multijunction colored solar cells [PDF]

arXiv, 2021
Colored solar cells suffer from lower efficiency due to reflection and absorption losses by coatings. By studying different types of coatings on solar cells, the spectrum parameters impacting the solar cell efficiency were identified. A collection of color coatings was fabricated and characterized using spectrophotometry and colorimetric photography ...

Predicted annual energy yield of III-V/c-Si tandem solar cells: modelling the effect of changing spectrum on current-matching [PDF]

Optics Express Vol. 28, Issue 6, pp. 7829-7842 (2020), 2018
High efficiencies of >30% are predicted for series-connected tandem solar cells when current-matching is achieved between the wide-bandgap top cell and silicon bottom cell. Sub-cells are typically optimised for current-matching based on the standard AM1.5G spectrum, but in practice, the incident radiation on a solar cell can be very different from this

The Potential of Singlet Fission Photon Multipliers as an Alternative to Silicon-based Tandem Solar Cells [PDF]

, 2018
Singlet fission, an exciton multiplication process in organic semiconductors which converts one singlet exciton into two triplet excitons is a promising way to reduce thermalization losses in conventional solar cells. One way to harvest triplet excitons is to transfer their energy into quantum dots, which then emit photons into an underlying solar cell.

Axial vs. Radial Junction Nanowire Solar Cell [PDF]

arXiv, 2021
Both axial and radial junction nanowire solar cells have their challenges and advantages. However, so far, there is no review that explicitly provides a detailed comparative analysis of both axial and radial junction solar cells. This article reviews some of the recent results on axial and radial junction nanowire solar cells with an attempt to perform

Novel heterojunction bipolar transistor architectures for the practical implementation of high-efficiency three-terminal solar cells [PDF]

Solar Energy Materials and Solar Cells, Volume 194, 1 June 2019, Pages 54-61, 2019
Practical device architectures are proposed here for the implementation of three-terminal heterojunction bipolar transistor solar cells (3T-HBTSCs). These photovoltaic devices, which have a potential efficiency similar to that of multijunction cells, exhibit reduced spectral sensitivity compared with monolithically and series-connected tandem solar ...

Carrier loss mechanisms in textured crystalline Si-based solar cells [PDF]

, 2017
A quite general device analysis method that allows the direct evaluation of optical and recombination losses in crystalline silicon (c-Si)-based solar cells has been developed. By applying this technique, the optical and physical limiting factors of the state-of-the-art solar cells with ~20% efficiencies have been revealed.

Graphene-Enhanced Thermal Interface Materials for Thermal Management of Photovoltaic Solar Cells [PDF]

Applied Sciences, 7, 589 (2017), 2016
The increase in the temperature of photovoltaic (PV) solar cells affects negatively their power conversion efficiency and decreases their lifetime. The negative effects are particularly pronounced in concentrator solar cells. Therefore, it is crucial to limit the PV cell temperature by effectively removing the excess heat.
