Summary: This study presents high performance semi-transparent perovskite solar cells with bidirectional transparent electrodes, showing significantly improved power conversion efficiency compared to typical PSCs. The fabrication of a transparent IZTO cathode through a two-step sputtering process demonstrates the feasibility of producing high-quality transparent top cathodes for semi-transparent PSCs. These results suggest that the FTS-based two-step sputtering technique has great potential for mass production of smart windows in building-integrated photovoltaics.

Summary: The design and development of low-cost and efficient photovoltaic materials is a major challenge for polymer solar cells (PSCs). In this study, a highly promising electron-donating polymer X1 with a simple chemical structure was synthesized. The carboxylate substituents on the polymer gave it good solubility, low-lying highest occupied molecular orbital (HOMO) energy level, and superior absorption. PSCs based on X1 as the donor achieved a high power conversion efficiency of 16.6% and a remarkable short-circuit current density of 27.07 mA cm(-2). This research shows the potential of carboxylated BDT as an effective building block for high-performance photovoltaic materials.
