Ensuring Lower Thermal Dissipation for Higher Efficiency

In this quest, they have come up with lithium polymer batteries, which will be a boon to the industry and consumers alike. These batteries support innumerable charge/discharge cycles, and will find application in mobile products and electric cars.

Lithium polymer batteries use polymer electrolyte instead of liquid electrolyte. Their composition is such that it improves heat dissipation, even during charging and discharging of the battery. However, the cost of the battery can be an issue as, Kamat says, these batteries will be four times costlier than the existing lithium-ion batteries.

Solar cells

A solar panel is a system made from innumerable solar cells, which are basically diodes. During conduction stage, these diodes emit heat, which affects the efficiency of the end-product.

To resolve the heat dissipation issue, solar panel designers have switched from silicon to cadmium-telluride in solar cells, which has increased their voltage range, thus ensuring lesser heat dissipation and higher efficiency.

“Solar cells are following the industry standards, which claim around 17.3 per cent efficiency for each cell,” says Mukherjee.

Neglecting thermal issues: a costly mistake

The rise in heat can crash the expensive design or reduce the lifespan of the components or the system. More heat dissipation indicates flaws in the design as it is not able to manage heat issues. Realising this, designers across sectors are constantly working towards reducing thermal dissipation in their products, thus making their products efficient and long-lasting.
