Abstract

This study presents a novel multilayered composite thin film of polyethylene glycol (PEG4000) sandwiched between two layers of polydimethylsiloxane (PDMS) with a prime focus on improving photovoltaic device efficiency and longevity. The PDMS/PEG/PDMS configuration absorbs heat from the device and near-infrared (NIR) sunlight thereby reducing thermal buildup and preventing material degradation. PDMS/PEG/PDMS film composite was fabricated using the doctor blade technique, this hydrophobic composite undergoes a solid-to-liquid phase transition at approximately 50–60 °C, enhancing thermal energy management. In its liquid state, the film composite exhibits 85.01 % visible transmittance and 11.11 % NIR reflectance, while in solid state, it shows 62.94 % visible transmittance and 13.40 % NIR reflectance. The phase change material (PCM) maintains cyclic stability without leakage and demonstrates a transparency shift with heat absorption, indicating effective thermal cycle stability.
