Technology Overview
Energy Harvesting Materials Gain Prominence as Smart Energy Management Solutions in Domestic and Industrial Space
Although energy harvesting materials were relatively unknown in the past, their unique properties have driven them to the spotlight in recent times. Technical advancements in the field have led to large-scale improvements, giving rise to high-efficiency energy scavenging solutions. Escalating energy prices have necessitated the development of cost-effective energy harvesting materials to decrease dependence on energy sources. Materials with the ability to support self powered devices were developed, pushing forward the growth of the piezoelectric (PE) and electromagnetic (EM) energy harvesting materials market. Other materials available nowadays capture light energy from sunlight at almost all wavelengths, thereby increasing energy density. “The design of a successful energy harvesting module depends not only on the material’s efficiency but also on the module architecture, which could be the critical factor defining effectiveness,” notes the analyst of this research service. “Developers must place equal emphasis on material development and smart utilization.” Incentives from governments and non-profit organizations have encouraged universities and industry participants to develop newer alternative materials for energy harvesting.
Even though the outlook for energy harvesting materials looks upbeat, there are some challenges that have overshadowed the landscape. High material prices have remained a spoke in the wheel for the industry and limited the use of several materials. Restrictions placed on the use of certain materials intended for the development of energy harvesting devices due to environmental concerns has deterred the use of a good number of potential materials. Within the piezoelectric (PE) materials, the most popular are the lead composites such as lead zirconate titanate (PZT).The use of lead in these energy harvesting materials has raised apprehensions. Apart from this, the increasing consumption of cadmium telluride for solar cell applications has diminished telluride resources, rendering it an unfeasible alternative. This has reined in the growth of thermal energy based harvesting, considering that bismuth telluride is the predominantly used material. Materials research requires in-depth understanding of material properties and design integration with devices to develop energy efficient and sustainable harvesting devices.
Several manufacturers from across the globe have deployed energy harvesting products for commercial use; however, large-scale production of devices has not yet been attained. Though research has identified various energy sources for harvesting energy, only a few techniques have proven useful for high-volume production. Hence, it is vital to evaluate the impact of different materials on these technologies in the market based on their success. “Recent trends in energy harvesting materials point to an exponential increase in the commercialization interest in four harvesting techniques - PE, thermo-electric (TE), EM, and photovoltaic (PV),” says the analyst. “These techniques pertain to different layers of applications such as electronics, automotive, medical, and aerospace, where each of these diverse domains are assumed to be equally critical in defining today’s and tomorrow’s energy harvesting.” In the case of thermoelectrics materials, the recent advances in mixtures of nanocomposite materials in a bulk matrix has triggered much interest and hope for these materials in the thermoelectric space. Such nanocomposites would enable higher ZT values by reducing thermal conductivity while maintaining favorable electronic properties. As material quality is fine tuned, the field of harvesting waste energy through thermoelectric devices will achieve greater prevalence.
