Clean energy plays a vital role in solving the environmental challenges such as reducing greenhouse gas emissions that pollutes the environment and involved in reducing the impacts due to the climate change. it also drives an economic development and improves the public health. among renewable energy sources, solar energy stands out as one of the most abundant and accessible source of energy. however, a major issue faced by solar panels is the heat which significantly reduces its efficiency. high temperatures impedes electron movement within solar cells, resulting in diminished electricity production. to mitigate this, cooling techniques have been integrated with solar panels. thermoelectric generators (tegs) acts as a passive cooling technique used for solar panels, which helps to dissipate heat while simultaneously serving as an additional power source to boost overall energy generation. despite the integration of tegs with photovoltaic (pv) systems, efficiency limitations persist due to spectral absorption constraints. to address this, a photothermal layer is introduced between the pv and teg. this layer absorbs light primarily in the near-infrared (ir) spectrum rather than the visible range. through the concept of photothermal effect, light energy is converted into thermal energy, making it highly advantageous for efficient energy applications. photothermal materials exhibit exceptional light-harvesting and conversion capabilities, enabling them to capture a wide range of the solar spectrum. the research focuses on developing a fabric based photothermal layer device which includes integrating a photothermal layer made of two-dimensional wide bandgap semiconductor materials coated onto fabrics. these materials are strategically placed between pv cells and tegs. the remarkable properties of semiconductor metal oxides such as high thermal stability and excellent photothermal conversion efficiency, allows them for efficient absorption of sunlight across a broad spectrum of wavelengths. this hybrid system not only improves the overall efficiency of solar energy conversion but also provides a sustainable solution for energy harvesting. experimental findings highlight substantial improvements in system performance, with the integrated device achieving a photothermal conversion efficiency of 54 %, a power output of 23 mw, and an overall efficiency of approximately 7.5 %. when black tio2 is used as the photothermal material coated on cellulose fabric, the device produces a voltage output of 4.6 v, compared to 2.3 v for standalone pv. uv characterization reveals band gaps of 2.50 ev for tio2 paste on cellulose fabric and 1.4 ev for black tio2 paste. thermal conductivity tests show values of 0.08 w/mk for black tio2 nanoparticles and 0.04 w/mk for their paste. thermal imaging demonstrates a 2.8°c temperature gradient in the pv-teg system with the photothermal layer. these findings underscore the potential of 2d semiconductor material-coated fabrics in advancing renewable energy technologies, offering significant improvements in solar energy utilization and promoting sustainable power generation.
