Abstract :
A novel, one-step and self-aligned selective emitter process has been tested on n-type solar cells. Results indicate that the electrical activity of acceptor impurities near the surface are responsible for increased surface recombination, not their physical presence. Lab-scale n-type solar cell efficiencies have been increased by up to 18.4%. Quantum efficiency measurements on these cells show dramatic increase in short wavelength response up to 750 nm.
