“…The ON and OFF states are repeatable, which clearly demonstrates the photoinduced current in the absence of any bias field. As presented in Table , the PCE of the h -LMO device under the upward poling is 0.11% (under AM 1.5G illumination), which is 1–3 orders higher than those of classical ferroelectric photovoltaics such as pure (undoped) BFO and PZT. ,,, Similar to h -LMO, h -YMO is also characterized by the switchable ferroelectric photovoltaic effect (Figure b). Another prominent feature of the h -RMO-based solar cells is that the PCE under the upward poling is remarkably higher than that under the downward poling (Table ).…”

“…The observed remanent polarization is ∼5 μC cm –2 . We have subsequently shown that the PCE (∼0.11%) of 150 nm thick h -RMnO 3 films is 1–3 orders higher than those of classical ferroelectric photovoltaics such as undoped Pb(Zr,Ti)O 3 and BiFeO 3 under the standard AM 1.5G illumination. ,,, On the basis of the poling-direction-dependent current–voltage ( J – V ) responses, we have further shown that the contribution from the switchable polarization effect to the photovoltage is much greater than that from the unswitchable internal field which arises from the net built-in potential developed in the h -RMnO 3 -based heterojunction solar cell.…”

Ferroelectric photovoltaics (FPVs) have drawn much attention owing to their high stability, environmental safety, anomalously high photovoltages, coupled with reversibly switchable photovoltaic responses. However, FPVs suffer from extremely low photocurrents, which is primarily due to their wide band gaps. Here, we present a new class of FPVs by demonstrating switchable ferroelectric photovoltaic effects using hexagonal ferrite (h-RFeO3) thin films having narrow band gaps of ~1.2 eV, where R denotes rare-earth ions. FPVs with narrow band gaps suggests their potential applicability as photovoltaic and optoelectronic devices. The h-RFeO3 films further exhibit reasonably large ferroelectric polarizations (4.7~8.5 μC•cm -2 ), which possibly reduces a rapid recombination rate of the photo-generated electron-hole pairs.The power conversion efficiency (PCE) of h-RFeO3 thin-film devices is sensitive on the magnitude of polarization. In the case of h-TmFeO3 (h-TFO) thin film, the measured PCE is twice as large as that of the BiFeO3 thin film, a prototypic FPV. We have further shown that the switchable photovoltaic effect dominates over the unswitchable internal field effect arising from the net built-in potential. This work thus demonstrates a new class of FPVs towards highefficiency solar cell and optoelectronic applications.

“…The observation of the electrodes affecting a ferroelectric photovoltaic device is indeed a very well-known effect (see e.g. [49], [50]). For any photovoltaic device in general the choice of the electrodes (and/or buffer contact-layers) is critically important (the literature on this topic is huge -see e.g.…”

The use of ultra-wide bandgap transparent conducting beta gallium oxide (-Ga 2 O 3) thin films as electrodes in ferroelectric solar cells is reported. In a new material structure for energy applications, we report a solar cell structure (a light absorber sandwiched in between two electrodes-one of them-transparent) which is not constrained by the Shockley-Queisser limit for open-circuit voltage (V oc) under typical indoor light. The solar blindness of the electrode enables a record-breaking bulk photovoltaic effect (BPE) with white light illumination (general use indoor light). This work opens up the perspective of ferroelectric photovoltaics which are not subject to the Shockley-Queisser limit by bringing into scene solar-blind conducting oxides.

The silicon based solar cells are expensive, and also said to have limited power conversion efficiency. Though a lot of organic, inorganic and organic-inorganic hybrid solar cells were developed, they could not sustain in long run. This has open doors for the development the ferroelectric based solar cells/photovoltaics. Because the ferroelectric based photovoltaics show high open circuit voltage, short circuit current/current density, unlimited power conversion efficiency, tunable bandgap, high polarization properties, etc. The main reason to shift the focus from semiconductor solar cells is,the ferroelectrics are said to be stable under changing environmental conditions. In addition, such materials help to develop thinner solar cells devices with low cost. Hence, an attempt has been made to understand the photovoltaic response of ferroelectric lead zirconate titanate (PZT). In this paper, we report the review on the photovoltaic properties of PZT films. The literature was collected from various internet sources.
