New Technology: Increased Solar Efficiency

By Hedrick Lepsch


Solar technology is constantly under revision as new techniques and materials are developed making this source of energy a viable option for governments, companies, and individuals. A newly developed heat-resistant material vastly improves the efficiency of solar panels by converting heat from the sun (high energy lights) into infrared light which can be absorbed by the solar cells and converted into electricity.

This is a huge step forward in thermophotovoltaics as previous experiments in the field failed to produce any worthy results. The technology consists of small tabs that sit on top of the solar panels.

You don't need to keep constant watch over them and your solar panels should be good for at least 25 - 30 years. Financial benefit Although it is more expensive to get solar panels at first, the savings will quickly rack up.

Many places offer large and substantial rebates and even different incentives to help your investment in solar energy. Imagine a day when you don't have to pay for your electricity. You can live off the grid, and be more safe for when you have financial difficulties.

The Chemistry When the lithium-ion battery is connected to an outside current and allowed to charge positively-charged lithium-ions are repelled from the positively charged cathode layer and are attracted to the negatively charged anode. The lithium ions are so small that they are able to pass through the separator due to the principle of micro-porosity. The positive ions are stored in the layered graphite structure of the anode effectively charging the battery. When the battery is used and energy is removed from the cell the charge of the cathode diminishes attracting the positive ions it originally lost.

The intermediary component is generally made of tungsten which is destroyed at temperatures of 1800 degrees but researchers have layered the tungsten emitters in a layer of ceramic material which allowed the tungsten to withstand 1800 degrees for twelve hours before losing structural integrity. At 2500 degrees the emitter functioned for a complete hour.

The tungsten covered in ceramic was still capable of producing infrared light from the heat absorbed making the technology potentially viable. While this may not appear too exciting at first glance it represents a huge step forward in thermophotovoltaics.

Tungsten and other similar materials like Hafnium are abundant and low cost. The focus is now on producing a thin ceramic layer that will allow the emitter to withstand high temperatures for extended periods of time. With the process of coating established it is hopefully a matter of years before a coating is developed to protect the emitters.

The Solar Panel Solar energy is something that everywhere is working towards. The phono solar 250 watt AC panel can be a great start for anyone who is looking to go green with solar panels.
