A solar cell uses the photoelectric effect to create an energy imbalance within the cell which can be used to drive some load.
Materials of high atomic energy may exhibit photoelectric absorption, the energy of gamma rays is then transferred to an electron, which is then ejected from the atomic shield.
Too much of the potential triggering energy of the degraded gammas is dissipated in Compton and photoelectric interactions.
It soon became clear in the next few years that the particles emitted in the photoelectric effect were indeed electrons.
A structure or space in the shadow of an efficient photoelectric generator surface already possesses this characteristic.
A science park developing photoelectricity products has recently been set up in Xi'an City,capital of northwest China's Shaanxi Province.
We selected four technological fields, namely gene, photoelectricity , Chinese traditional medicine, and nano, in which China has advantages and potential markets.
