Abstract

High quality III-Vs on Si are a promising candidate for high efficiency, cost-effective tandem solar cells due to the superior optoelectronic properties of III-Vs and low cost of Si. In recent years, progress towards the integration of high-quality, monolithically-grown III-Vs on Si has been made through careful control of the GaP on Si nucleation step [1]. A variety of pretreatments have successfully been used to modify the surface reconstruction of the Si to prevent the formation of antiphase domains (APDs) [2]- [5]. This has led to promising III-V/Si multijuction solar cell results, with efficiencies now exceeding 20% [6], [7].
