Japanese electronics maker Panasonic has developed as artificial Photosynthesis System that uses Sunlight to convert carbon dioxide (CO2)into organic material (called formic acid) at efficiency of 0.29%. This Development will make it possible to realise a simple and compact system for capturing and converting wasted carbon dioxide from incinerators and electric generation plants, according to the company.
The efficiency is said to be on a comparable level with real plants used for biomass energy. What makes this artificial photosynthesis system simple and efficient is the application of a nitride semiconductor.
“We found that nitride semiconductor has the capability to excite the electrons with enough high energy for the CO2 reduction reaction. Nitride Semiconductor has attracted attention for its potential applications in highly efficient optical and power device for energy saving. However, its potential was revealed to extend beyond solid devices; more specifically, it can be used as a photo-electrode for CO2 reduction. Making a Device structure through the thin film process for semiconductors, the performance as a photo-electrode has highly improved”
