In order to surmount the Shockley–Queisser efficiency barrier of single-junction solar devices, tandem cells (TSCs) have shown a potential solution. Organic and Si materials can be promising candidates for front rear in TSCs due their non-toxicity, cost-effectiveness, possible complementary bandgap properties. This study researches flexible two-terminal (2-T) organic/Si TSC through TCAD simulation. proposed configuration, organic cell (OSC), with photoactive optical 1.78 eV, serves as cell, while comprises based on thin 70 μm wafer, energy 1.12 eV. The individual standalone bottom cells, upon calibration, demonstrate power conversion efficiencies (PCEs) 11.11% 22.69%, respectively. When integrated into 2-T monolithic TSC, resultant achieves PCE 20.03%, indicating need optimization top beat cell. To enhance performance OSC, some design ideas are presented. Firstly, OSC is designed by omitting hole transport layer (HTL). Consequently, engineering contact work function, enhanced. Moreover, influence varying absorber defect density investigated. Reduced led an overall improvement 23.27%. Additionally, effects variation thicknesses metrics explored. With matching condition design, enhanced 27.60%, VOC = 1.81 V JSC 19.28 mA/cm2. presented simulation results intimate that OSC/Si find applications wearable electronics flexibility, environmentally friendly high efficiency.

Efficient cathode interfacial layers (CILs) have become a crucial component of organic solar cells (OSCs). Charge extraction barriers, trap states, and significant transport resistance may be induced due to the unfavorable interlayer, limiting device performance. In this study, poly(4-vinylpyridine) is used as CIL for OSCs, new type named P4VP-I synthesized through quaternization strategy. Compared P4VP, exhibits enhanced conductivity optimized work function. OSCs employing ETL demonstrate prolonged carrier lifetime, suppressed charge recombination, achieve higher power conversion efficiencies (PCE) than commonly ETLs such PFN-Br Phen-NaDPO.
