This paper demonstrates that perovskite solar cells with a semi-transparent electrode can achieve significantly higher efficiency under dual-irradiation from both sides compared to single-side illumination, enhancing solar energy harvesting.

Contribution

The study introduces a novel PSC architecture with a semi-transparent Au/ITO electrode enabling dual-irradiation, resulting in improved power conversion efficiency.

Findings

Achieved 20.1% PCE under dual-irradiation at 1.4 sun

Dual-irradiation significantly outperforms single-irradiation in efficiency

Demonstrated potential for enhanced solar cell performance with semi-transparent electrodes

Abstract

In general, perovskite solar cells (PSC) with a sensitized or thin film architecture absorb light from a single illumination. This paper reported a PSC architecture with a semitransparent Au/ITO counter electrode, which allows light to pass it partially. When the device was illuminated simultaneously from both the FTO and Au/ITO sides, the PSC has achieved an overall power conversion efficiency (PCE) as high as 20.1% under high light intensity (1.4 sun), which is much higher than that of the single-irradiation system.
