Numerical analysis is a tool that is helping engineers over the past decades in design optimization and low-cost fabrication of solar cell devices. The need of modeling tools is used to deeply analyze a device in a soft environment where the time and cost both can be saved before putting a device into fabrication. In this study, lead iodide-based perovskite solar cells were modeled having several feasible planar pin structures for known electron and hole transport layers. The primarily taken pin device structure for analysis was PEDOT:PSS/MAPbI 3 (I)/PCBM. A total of seventy-two different structures were analyzed. From our results, thirty-seven devices have achieved a maximum efficiency of 21%. The best device structure has achieved a 23.29% PCE. Our proposed results can provide imperative guidelines to researchers for the design of efficient pin structure perovskite solar cells.

In addition to the broadly anticipated use of metal halide perovskites in photovoltaics and light-emitting devices, they also hold a great promise as cost-effective thermoelectrics, as they may offer an ultra-low thermal conductivity combined with a high Seebeck coefficient. This Review summarizes the recent advances in theoretical analysis and experimental studies of the thermoelectric properties of these materials, with a particular focus on organic–inorganic (hybrid) halide perovskites and low-dimensional analogues. After a short introduction of figures of merits of thermoelectric materials, we consider measurement methods used to characterize thermoelectric materials and outline some difficulties in applying those methods to perovskites, since accurate measurements are essential for further progress of this emerging research area. We then outline in detail the current progress achieved in metal halide perovskite thermoelectrics and offer a detailed discussion of possible strategies to resolve the discrepancy between their high theoretically predicted ZT values (1–2 at room temperature) and still rather low (below 0.2) experimental values.

“…Towards commercialization of PSCs, further reducing the cost and increasing the stability are necessary. Due to the high chemical reactiveness of the metal halide perovskite, even the inert noble metal electrodes, such as Au and Ag, cannot survive [5,6]. Carbon electrodes, one of the most promising substitutions, now attract more and more attention (figure 1(a)) for their low cost and potential stability.…”

For commercialization, further reducing the cost and increasing the stability of perovskite solar cell (PSC) have been the most essential tasks for researchers, since the efficiency of single-junction PSCs has reached a competitive level among all kinds of single-junction solar cells. Carbon-electrode-based PSCs (CPSCs), as one of the most promising constructions for achieving stable economical PSCs, now attract enormous attention. Here, we briefly review the development of CPSCs and reveal the importance of the n-i-p architecture for state-of-the-art CPSCs. Despite the promise, challenges still exist in CPSCs of n-i-p architecture, which mainly steam from the incompact contact of hole transporting layer (HTL)/carbon electrode. Thus, new carbon materials and/or novel manufactural methods should be proposed. Specifically, HTL is yet to be appropriate for state-of-the-art CPSCs since the solution process of carbon electrode may destroy the underlayer. And for further enhance the performance of CPSCs, both HTL and electron transporting layer (ETL) as well as their interfaces with perovskite active layer need to be improved. Besides, we recommend that the perovskite active layer with long carrier lifetime, strong carrier transport capability and long-term stability is of significance as well. We highlight the current researches on CPSCs and provide a systematic review of various types of regulation tools.

Abstract: The microstructure of the metal contact has a significant influence on the PSC aging properties. In this contribution we show that perovskite decomposition and iodide diffusion can be suppressed by using nanocrystalline Ni metallization.
