Investigation of Al-Doped Emitter on N-Type Rear Junction Solar Cells

WebA new method for fabricating crystalline silicon solar cells with selective emitters is presented. In this method, shallow trenches corresponding to metal contact area are first formed by screen printing and chemical etching, followed by heavy doping over the whole front surface of the silicon wafer. WebSelective emitter is the key to achieve spectral reshapement. The selective emitter designed in this paper is considered to match high-bandgap cell such as Si. Due to the short cut-off … scientist that study space called
