Laser doping for selective emitter solar cells

چکیده
Selective emitter solar cells were fabricated with a reduced number of technological steps. Laser doping is often discussed in relation to silicon photovoltaic cell efficiency enhancement. In this paper, we present results of the development of a selective emitter structure for multicrystalline silicon solar cells suitable for industrial mass production. A pulsed laser is used to obtain highly doped regions that will receive the screen printed silver grid. Therefore, we designed using solidworks software a single type of pattern for square cells (multicrystalline silicon). We resolved the problem of grid mismatch between the laser pattern and metallic grid. Observation of laser treatment surface shows the perfect continuity of the lines and good flatness of the edge of finger and bus bar.

Laser Doped Solar Cell on CZ P - type Silicon , IEEE 35 th PVSC
For many years, the selective emitter approach has been well-known to yield cell efficiencies well above those achieved by conventional screen-printed cells. A simple and effective way of forming a selective emitter can be achieved by laser doping to simultaneously pattern the dielectric with openings as narrow as 8 m, and create heavy doping beneath the metal contacts. In conjunction with las...

In this work, we describe a novel fabrication process of p-type interdigitated back contact (IBC) silicon solar developed by means of laser doping and laser firing techniques. We use dielectric layers both as dopant sources to create highly-doped regions and as passivating layers. In particular, we use phosphorus-doped silicon carbide stacks (a-SiCx (n)) deposited by Plasma Enhanced Chemical Va...

Self-aligned selective-emitter cells have been fabricated using a self-doping paste by co-firing the front and back contacts. Good ohmic contacts with ~0.774 fill factor were obtained on 100 Ω/sq. emitters after alloying the self-doping Ag grid by a 900°C spike firing in a belt furnace. Screen-printed selective emitter Fz Si cells gave an efficiency of 16.4%. Selective-emitter cells with effect...

In recent years, laser doping of selective emitters (LDSE) has demonstrated great promise for improving c-Si solar cell performance with the potential for low cost of adaptation. Absolute cell efficiency improvement of 1 – 2 % is seen with a process pioneered at the University of New South Wales which couples narrow-line LDSE processing with a self-aligning, light-induced plating (LIP) metalliz...
متن کاملSelective emitter using a screen printed etch barrier in crystalline silicon solar cell
The low level doping of a selective emitter by etch back is an easy and low cost process to obtain a better blue response from a solar cell. This work suggests that the contact resistance of the selective emitter can be controlled by wet etching with the commercial acid barrier paste that is commonly applied in screen printing. Wet etching conditions such as acid barrier curing time, etchant co...
