Abstract The present work investigates a tin-based highly efficient perovskite solar cell (PSC) by a solar cell capacitance simulator in one dimension. Molybdenum disulfide is introduced as hole transport layer in the proposed solar cell device structure. The photovoltaic performances of the proposed solar cell are investigated by varying thickness, doping concentration, and bulk defect density of various layers. Furthermore, the operating temperature and the series and shunt resistances are analyzed systematically. A higher conversion efficiency of 25.99% is obtained at the absorber thickness of 2000 nm. The optimum doping density of 1017 cm−3 is estimated for the absorber, electron transport layer (ETL), and hole transport layer (HTL), respectively. The optimum thicknesses of 50 nm, 1000 nm, and 60 nm are also found for the titanium dioxide as ETL, methylammonium tin triiodide (CH3NH3SnI3) as absorber layer, and molybdenum disulfide as HTL, respectively. The efficiency of the proposed lead-free CH3NH3SnI3-based solar cell with the alternative molybdenum disulfide HTL is calculated to be 24.65% with open-circuit voltage of 0.89 V, short-circuit current density of 34.04 mA/cm2, and fill-factor of 81.46% for the optimum parameters of all layers. These findings would contribute to fabricate low-cost, non-toxic, stable, and durable lead-free PSCs for the next generation.

Abstract Fill factor (FF) deficit and stability is a primary concern with the perovskite solar cell. Resistance values and band alignment at junction interface in perovskite are causing low fill factor. Moisture sensitivity of methylammonium lead halide perovskite is causing a stability issue. We tried to solve these issues by using inorganic hole transport layer (HTL). FF is sensitive to the band offset values. We study the band alignment/band offset effect at the Perovskite /HTL junction. Inorganic material replacing Spiro-MeOTAD can enhance the stability of the device by providing an insulation from ambient. Our simulation study shows that the earth abundant p-type chalcogenide materials of SnS as HTL in perovskite is comparable to Spiro-MeOTAD efficiency.

Inorganic-organic mesoscopic solar cells become a promising alternative for conventional solar cells. We describe a CH3NH3PbI3 perovskite-sensitized solid-state solar cells with the use of different polymer hole transport materials such as 2,2′,7,7′-tetrakis-(N,N-di-p-methoxyphenyl-amine)-9,9′-spirobifluorene (spiro-OMeTAD), poly(3-hexylthiophene-2,5-diyl) (P3HT), and poly[[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl]] (PTB7). The device with a spiro-OMeTAD-based hole transport layer showed the highest efficiency of 6.9%. Interestingly, the PTB7 polymer, which is considered an electron donor material, showed dominant hole transport behaviors in the perovskite solar cell. A 200 nm thin layer of PTB7 showed comparatively good efficiency (5.5%) value to the conventional spiro-OMeTAD-based device.

Research in solar cells is needed to maximize Indonesia’s vast solar potential that can reach up to 207.898 MW with an average radiation of 4.8 kWh/m2/day. Organometallic perovskite solar cells (PSCs) have gained immense attention due to their rapid increase in efficiency and compatibility with low-cost fabrication methods. Understanding the role of hole transport layer is very important to obtain highly efficient PSCs. In this work, we studied the effect of Hole Transport Layer (HTL) to the performance of perovskite solar cell. The devices with HTL exhibit substantial increase in power conversion efficiency, open circuit voltage and short circuit current compared to the device without HTL. The best performing device is PSC with CuSCN as HTL layer, namely Voc of 0.24, Isc of 1.79 mA, 0.27 FF and efficiency of 0.09%.
