“…The cell's performance parameters, such as V oc and J sc , are influenced by temperaturec. [ 60 ] To investigate this effect, the temperature of the cells was systematically varied within the range of 280–460 K. The relationship between temperature, J sc , and V oc is described by Equation (14):

V_{\text{oc}} = \frac{n K T}{q} log \left(\right. \frac{J_{\text{sc}}}{J_{\text{o}}} + 1 \left.\right)

As shown by the results in Figure 28 , an exponential increase in reverse saturation current occurs with rising temperature, leading to a decline in V oc .…”

CTL have remarkable influence on the stability and efficiency of PSC. Different CTL combination used with the perovskite forms unique energy band alignment and electric field. They have significant effects on the optoelectrical properties of PSC. Identifying the right CTL for perovskite is crucial. In this work, the PSC of CH3NH3GeI3 are modeled in SCAPS‐1D with 13 CTL. Because of their high carrier‐mobility, chemical‐stability, and excellent electric/thermal conductivity, copper, kesterite and carbon CTL have been selected. The PSC was analyzed in planar(n‐i‐p) and inverted(p‐i‐n). A systematic approach has been adopted to analyze the influence of CTL on the quantum‐efficiency, absorption, transmissivity, band‐alignment, electric‐field, recombination, and IV‐characteristics in both architectures. To further enhance the efficiency, design optimization of layer thickness and doping has been carried‐out. Moreover, the effect of defects, temperature, reflection, and front/back workfunctions on the performance of PSC has also been studied. Based on the results PCBM performed better in planar while C60 performed better in inverted. Most of the Cu‐HTL performed better in inverted architecture while most of the kesterite‐HTLs performed better in planar architecture. The best‐performing inverted perovskite structures was PCBM/Per/CuAlO2 with PCE of 24.32 %, while the best planar structure was C60/Per/CuAlO2 with PCE of 14.82 %.This article is protected by copyright.

“…While these PCE values are lower than record efficiencies of >21% for FAPbI 3 solar cells, , we expect further improvements can be achieved through optimization of the electron and hole transport layers. Promisingly, the J SC values of FAPbI 3 nanowire solar cells are approaching the highest reported values for FAPbI 3 solar cells of 26–27 mA cm –2 . ,− Enhanced J SC values for nanowire-based photovoltaic devices compared to their thin-film counterparts have been reported for silicon solar cells due to larger available surface areas for charge transfer. − Furthermore, α-FAPbI 3 formed directly during PbI 2 immersion in FAI and FAI/BAI solutions, precluding the need for a high temperature annealing step to convert δ-FAPbI 3 to α-FAPbI 3 .…”

Perovskite nanowire arrays with large surface areas for efficient charge transfer and continuous highly crystalline domains for efficient charge transport exhibit ideal morphologies for solar-cell active layers. Here, we introduce a room temperature two-step method to grow dense, vertical nanowire arrays of formamidinium lead iodide (FAPbI 3 ). PbI 2 nanocrystals embedded in the cylindrical nanopores of anodized titanium dioxide scaffolds were converted to FAPbI 3 by immersion in a FAI solution for a period of 0.5–30 min. During immersion, FAPbI 3 crystals grew vertically from the scaffold surface as nanowires with diameters and densities determined by the underlying scaffold. The presence of butylammonium cations during nanowire growth stabilized the active α polymorph of FAPbI 3 , precluding the need for a thermal annealing step. Solar cells comprising α-FAPbI 3 nanowire arrays exhibited maximum solar conversion efficiencies of >14%. Short-circuit current densities of 22–23 mA cm –2 were achieved, on par with those recorded for the best-performing FAPbI 3 solar cells reported to date. Such large photocurrents are attributed to the single-crystalline, low-defect nature of the nanowires and increased interfacial area for photogenerated charge transfer compared with thin films.
