Silicon solar cells: at the crossroads

Abstract

Although the silicon solar cell industry had developed to a stage where it produced reasonably standardised products by the early 1980s, the last 5 – 10 years have seen increased diversification in manufacturing approaches. Facets of this diversification are discussed, as are implications for the future. In the future, silicon cells will be thinner, more efficient and cheaper, although there is considerable uncertainty about other features. Copyright © 2000 John Wiley & Sons, Ltd

Design and Optimization of a Triple‐Cation Perovskite Solar Cell for Efficiency Promotion using Numerical Simulations

“…Figure 11 depicts the effect of temperature on the PV parameters including J sc , V oc , FF and PCE corresponding to the working temperature from 300 K to 400 K for the proposed device simulated under 1000 W⋅m −2 solar light. It is worth noting that V oc , FF, and PCE decrease as the temperature rises whereas J sc value shows a slight increase with temperature since the band gap energy decreases and more photons have sufficient energy to form electron‐hole pairs [36] . A casual inspection of the equation (1) implies that V oc rises linearly with temperature.…”

However, this is not the case as V oc decreases from 1.19 V to 1.03 V with increase in the temperature.…”

Mathematical Approach to Photonic Analysis of Ag-Doped HfO₂ for Antireflective and Intermediate Reflective Applications in Planar a-Si Solar Cells

“…Figure 3(a) shows how the Maxwell-Garnett effective medium theory (EMT), which predicts the composite behaviour of metal-dielectric mixtures 29,30 was used to compute the effective real and imaginary components of permittivity.The results show that the real fraction of the effective permittivity (ε′) declines rapidly with increasing silver concentration and crosses into negative values across the visible wavelength range (400-700 nm), confirming ENZ and negative permittivity behaviour. The ENZ regime is very appealing in nanophotonic applications for improving optical tunnelling and field confinement [3,4]. Simultaneously, the imaginary portion (ε′′) increases with silver concentration, implying greater plasmonic absorption from metal inclusionsa tradeoff that requires careful optimisation in photovoltaic design 31,32 .…”

Design of a neural network control scheme for the maximum power point tracking (MPPT)

“…The voltage characteristic equation of a cell obtained in generating mode is the same as one of a module, with one more parameter which indicates the number of cells in series ( Z ). So the equation of the module is as follows [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]: In average, each cell can provide a continuous nominal voltage of 0,6 volts, thus to obtain a voltage higher than 12 volts it is necessary to put several cells in series. Figure 2 shows the module voltage and power behaviour with 36 identical cells.…”
