Synergetic Effect Of Aluminum And Thermally Treated Porous Silicon For Bulk Passivation Of Multicrystalline Silicon

Utilizing the hydrogen-rich porous surface and aluminum ability to generate vacancies a new passivation scheme is proposed for mc-Si solar cells with porous silicon as an antireflection coating and aluminum as a back contact. This combination achieves a synergetic effect with aluminumn providing injection od vacancies through which hydrogen atoms from the porous silicon surface can diffuse into the mc-Si and effectively passivate the bulk.
