“…Doping the NiO layer with atoms as copper, cobalt, strontium and cesium has resulted in enhanced optoelectronic properties of the oxide-based hole transport media and better overall PCE [515] , [517] , [518] , [191] . For example, Kim et al [515] increased the NiO HTM conductivity up to a value of ~8x10 -4  -1 cm -1 for Cu-doped (the undoped conductivity was only 2x10 -6  -1 cm -1 ) which, in turn, resulted in an increase of the HPSC photocurrent from 14.13 mA/cm 2 up to a value of 18.75 mA/cm 2 together with larger photovoltages (1.1 V) owing to better band alignment.…”

New device concepts and new computing principles are needed to balance our ever-growing appetite for data and information with the realization of the goals of increased energy efficiency, reduction in CO 2 emissions and the circular economy. Neuromorphic or synaptic electronics is an emerging field of research aiming to overcome the current computer's Von-Neumann bottleneck by building artificial neuronal systems to mimic the extremely energy efficient biological synapses. The introduction of photovoltaic and/or photonic aspects into these neuromorphic architectures will produce self-powered adaptive electronics but may also open up new possibilities in artificial neuroscience, artificial neural communications, sensing and machine learning which would enable, in turn, a new era for computational systems owing to the possibility of attaining high bandwidths with much reduced power consumption. This perspective is focused on recent progress in the implementation of functional oxide thinfilms into photovoltaic and neuromorphic applications towards the envisioned goal of selfpowered photovoltaic neuromorphic systems or a solar brain.

“…108 On the other hand, doping a material like nickel oxide usually increases electrical conductivity. 108,132,[139][140][141][142] Wei et al doped nonstoichiometric nickel oxide hole transporting material with silver and obtained an efficient and environmentally stable perovskite device. 131 The dopant increased the work function, conduction of electrons, movement of holes from the perovskite to the HTM, transparency of the device to light; which invariably increased the device performance and stability over time.…”

“…polyethylene terephthalate (PET) and polyethylene naphthalate (PEN), which registered low PCEs [5,13,73,76,108]. Moreover, the need for improved stability, cost-effectiveness and efficiency, have directed researchers to rethink the architecture and formulation of perovskite devices, by application of various organic composites and co-polymers, such as PCBM (phenyl-C61-butyric acid methyl ester), P3HT (poly(3-hexylthiophene) and PEDOT:PSS (poly(3,4-ethylenedioxythiophene) polystyrenesulfonate) [109,110], different carbon allotropes (carbon nanotubes, graphene and fullerene) [109,111,112], and alternative metal oxides (Al 2 O 3 , ZnO, SnO 2 , NiO x ) [113][114][115][116][117][118]. Figure 2a displays the typical structure of direct stacked (n-i-p) architecture of a standard thin film perovskite solar cell and the arrangement of molecules in a single perovskite unit.…”

Perovskite-based solar cells with high power conversion efficiencies (PCEs) are currently being demonstrated in solid-state device designs. Their elevated performances can possibly be attained with different non-standard geometries, for example, the fiber-shaped perovskite solar cells, in the light of careful design and engineering. Fiber-shaped solar cells are promising in smart textiles energy harvesting towards next-generation electronic applications and devices. They can be made with facile process and at low cost. Recently, fiber-shaped perovskite solar devices have been reported, particularly with the focus on the proof-of-concept in such non-traditional architectures. In this line, there are so many technical aspects which need to be addressed, if these photovoltaic (PV) cells are to be industrialized and produced massively. Herein, a well-organized and comprehensive discussion about the reported devices in this arena is presented. The challenges that need to be addressed, the possible solutions and the probable applications of these PV cells are also discussed. More still, the perovskite fiber-shaped PV cells with other fiber PV devices reported in literature in terms of their scope, characteristic designs, performances, and other technical considerations have been summarised.
