Autonomous Power Efficient Microchips Generating Its Own Power.

          Solar cell generated within the layers of microchip

Power management and reduction of area required in a microchip are the two most important fields researchers are working upon.
Autonomous chips are created by harvesting solar energy to meet the power supply requirement of the chip by embedding a solar cell separately at its top. 

This type of chips won't require any battery or any other external energy sources. Hence they are very useful in wireless communication and space technology for their power efficiency.
But researchers have now succeeded in finding out a more efficient production process.They used a chip as a base and applied the solar cell to it layer by layer. 

One major advantage of this is that the chip would require fewer materials and hence performance would increase. Also it is highly suitable for industrial serial production.
The prototypes so far constructed showed that the electronics and the solar cell worked perfectly.
