China Energy Savings Technology, Inc. , a leading provider of energy saving products in China, announced today it has entered into a Letter of Intent with Beijing Zhongmei Chengxin Technology Ltd. ("Beijing Zhongmei") to develop Thermo-photovoltaic Cell Technology
This new solar cell can absorb visible light, including a certain amount of ultra-red light at a thermo-photovoltaic conversion rate of over 35 percent.
The products offer several advantages versus established solar technologies. Based upon a cost of less than $2 per watt, it is much more cost effective. Its small size also provides an additional advantage. It also can absorb the solar radiation energy as well as environmental heat from its surroundings, in contrast to solar batteries, which cannot absorb ultra-red energy in a short distance. The reverse bias being added to the thermo-photovoltaic cell accelerates electronic flow speed, creating a tunnel effect that contributes to the drastic increase in current, which solar batteries are unable to achieve.
