Despite the fact that perovskite solar cells (PSCs) have a strong potential as a next-generation photovoltaic technology due to continuous efficiency improvements and the tunable properties, some important obstacles remain before industrialization is feasible. For example, the selection of low-cost or easy-to-prepare materials is essential for back-contacts and hole-transporting layers. Likewise, the choice of conductive substrates, the identification of large-scale manufacturing techniques as well as the development of appropriate aging protocols are key objectives currently under investigation by the international scientific community. This Review analyses the above aspects and highlights the critical points that currently limit the industrial production of PSCs and what strategies are emerging to make these solar cells the leaders in the photovoltaic field.

“…Downconversion (also known as quantum cutting or quantum splitting) involves conversion of one high-energy photon into two or more lower-energy photons [1,2]. Efficient downconversion materials are of great interest for application in solar cells [3][4][5][6][7][8], lighting, and displays [9][10][11][12][13]. Lanthanide ions are suitable candidates for downconversion because they have a rich energy-level structure with discrete energy levels that offer a wide variety of options for downconversion in different spectral regions [14][15][16][17].…”

Y 2 O 3 codoped with Bi 3+ and Yb 3+ is considered as an efficient downconversion material combining strong broadband absorption of Bi 3+ with photon splitting by cooperative energy transfer from Bi 3+ to two Yb 3+ neighbors. However, evidence for photon splitting is lacking. Here we investigate the Bi 3+-to-Yb 3+ energy-transfer mechanism. For cooperative energy transfer the Yb 3+-concentration-dependent luminescence decay will show clear characteristics of cooperative dipole-dipole transfer. Analysis of Yb 3+-concentration and temperature-dependent decay curves however demonstrates that the energy-transfer mechanism is not cooperative but single step, probably through a Bi 4+-Yb 2+ charge-transfer state. The temperature dependence of the Bi 3+-to-Yb 3+ energy-transfer efficiency is unusual as it decreases with temperature, unlike commonly observed thermally activated energy transfer. This is a signature of energy transfer via exchange interaction. The present results provide evidence for the absence of photon splitting in Y 2 O 3 : Bi 3+ , Yb 3+ and form a convincing demonstration of exchange interaction mediated energy transfer.

“…Several ways to improve the SC efficiency 6 are thus investigated such as tandem cells, 7,8 surface texturing, 9,10 antireflective layer, [11][12][13] or frequency conversion layer. 2,[14][15][16][17][18][19][20] In that respect, down conversion (DC) answers the thermalization issue by converting high energy photons to a greater number of lower energy photons with energies close to the Si-SC gap. Many systems using a couple of rare earth (RE) ions, such as Pr 3+ -Yb 3+ , [21][22][23] Tb 3+ -Yb 3+ , [24][25][26][27] and Ce 3+ -Yb 3+ , 28,29 have been studied for the DC approach.…”

Down converter SiNx:Yb3+/SiNx:Tb3+ multilayers are deposited by reactive magnetron cosputtering with the objective of optimizing the interaction distance between Tb3+ and Yb3+ ions to favor a better light management in Si solar cells. Those Si‐based multilayers are developed to be compatible with the Si photovoltaic technology. The deposition parameters are optimized to enhance the emission of the Yb3+ ions in the IR region. The emission efficiency of such multilayer structure is compared with a mixed RE SiNx:Tb3+‐Yb3+ layer evidencing a gain resulting from a better management of the Tb3+ and Yb3+ ions distance. At the end, we integrate the growth of such a multilayer in an industrial Si solar cell process and demonstrate the existence of a frequency conversion effect that is promising for the future increase of the Si solar cell efficiency.
