Reducing hole transporter use and increasing perovskite solar cell stability with dual-role polystyrene microgel particles
Abstract
Perovskite solar cells (PSCs) are a disruptive technology that continues to attract considerable attention due<br/>to their remarkable and sustained power conversion efficiency increase. Improving PSC stability and reducing<br/>expensive hole transport material (HTM) usage are two aspects that are gaining increased attention. In<br/>a new approach, we investigate the ability of insulating polystyrene microgel particles (MGs) to increase PSC<br/>stability and replace the majority of the HTM phase. MGs are sub-micrometre crosslinked polymer particles<br/>that swell in a good solvent. The MGs were prepared using a scalable emulsion polymerisation method.<br/>Mixed HTM/MG dispersions were subsequently spin-coated onto PSCs and formed composite HTM-MG<br/>layers. The HTMs employed were poly(triaryl amine) (PTAA), poly(3-hexylthiophene) (P3HT) and Spiro-<br/>MeOTAD (Spiro). The MGs formed mechanically robust composite HTMs with PTAA and P3HT. In contrast,<br/>Spiro-MG composites contained micro-cracks due the inability of the relatively small Spiro molecules to<br/>interdigitate. The efficiencies for the PSCs containing PTAA-MG and P3HT-MG decreased by only ∼20%<br/>compared to control PSCs despite PTAA and P3HT being the minority phases. They occupied only ∼35 vol%<br/>of the composite HTMs. An unexpected finding from the study was that the MGs dispersed well within the<br/>PTAA matrix. This morphology aided strong quenching of the CH3NH3PbI3−xClx fluorescence. In addition,<br/>the open circuit voltages for the PSCs prepared using P3HT-MG increased by ∼170 mV compared to<br/>control PSCs. To demonstrate their versatility the MGs were also used to encapsulate P3HT-based PSCs.<br/>Solar cell stability data for the latter as well as those for PSCs containing composite HTM-MG were both far<br/>superior compared to data measured for a control PSC. Since MGs can reduce conjugated polymer use and<br/>increase stability they have good potential as dual-role PSC additives.
