The research topics of our lab are related to devices for optical energy conversion, such as solar cells and photodetectors. In the past, we have demonstrated that graphene oxide (GO) has the potential to passivate the surface of photodetectors and solar cells. We would like to utilize the passivation effect on more devices in the future. We found that the passivation effects contributed by GO will degrade with high-temperature treatment. This founding encourages us to develop solar cell process without high-temperature damage on GO. We will investigate the effect of transition metal oxide on p-Si and n-Si to develop the low-temperature or nontoxic process for solar cells. On the other hand, we have demonstrated Ge photo-diodes with ultra-high responsivity with gold nanoparticle assistance in the past. The responsivity can reach 37. 7 A/W, which corresponds to a gain of 76. Such a high responsivity originates from the amassment of holes in Ge under the boundary of gold nanoparticles, which reduces the barrier for electrons tunneling from metal to Ge. We would like to apply the mechanism on thin-film Ge to save the consumption of expensive Ge material and keep the responsivity high. Welcome to join us.
