Mitsubishi Electric Corp is taking its solar cell technology seriously with its newly acquired cell conversion efficiency of 19.3%. This was with a polysilicon solar cell that measured 15 x 15 cm. This figure is more than the 19.1% conversion efficiency achieved last September by the company. The company has been breaking its efficiency record with its polysilicon cells since the last three years. Mitsubishi added a cleaning process before the electrodes are formed on the front and back of a silicon wafer due to which the connection resistance between the silicon wafer and the electrodes was reduced by 4%. This polysilicon solar cell has a thickness of 200μm due to which the 19.3% was achieved.
A similar technology has been applied to a 100μm-thick cell that will help reduce costs and achieve a conversion efficiency of 18.1%. Mitsubishi Electric Corp love breaking their own records, don’t they?
