A review on two-dimensional (2D) perovskite material-based solar cells to enhance the power conversion efficiency

With perovskite materials, rapid progress in power conversion efficiency (PCE) to reach 25% has gained a significant amount of attention from the solar cell industry.

Efficiency improvement for perovskite-inspired Cs3Sb2I9 solar cells using P3HT as the hole transport material

In this work, we introduce P3HT (poly(3-hexylthiophene-2,5-diyl)) as an efficient hole transport material (HTM) for lead-free Cs3Sb2I9 perovskite-inspired solar cells. The P3HT doubles the power conversion efficiency (PCE) of the...

Attributed to the rapid development of benzodithiophene (BDT) centered small molecule donors, all small molecule organic solar cells (ASM-OSCs) have achieved comparable power conversion efficiency (PCE) (>15%) along with high...

Effects of Preheating Treatments on the Performance of Perovskite Solar Cells

Perovskite solar cells (PSCs) have fascinated widespread focus for prominent perfomances recently. The processing parameters in spin-coating have great influence on the efficiency of PSCs. Herein, we have researched the influence of different preheating treatments on the perfomance of PSCs. The power conversion efficiency (PCE) has a significant enhancement to 15.89% through preheating the substrate together with precursor solution simultaneously. This work promotes the development of high performance PSCs and their industrialization.

Dopant-Free Hole Transport Material Boosting the Performance of Inverted Methylamine-Free Perovskite Solar Cells

The great progress in power conversion efficiency (PCE) for methylamine (MA)-free inverted perovskite solar cells (PSCs) is inseparable from the rapid development of the hole transport layers (HTLs). We design...
