Ambient stability of wet chemically passivated germanium wafer for crystalline solar cells
Surface passivation has been recognized as a crucial step in the evaluation of minority carrier lifetime of photovoltaic materials as well as in the fabrication of high efficient solar cells. Dilute acids of [...]
Rectifier is a controllable rectifier device based on controllable silicon (thyristor) and centered on intelligent digital control circuits, which converts AC to DC. It is abbreviated as silicon rectifier, also known as thyristor rectifier, thyristor rectifier, etc. Silicon rectifier advantages include high efficiency, no mechanical noise and wear, [...]

Silicon-based devices are approaching physical limits, and compound semiconductors have broad prospects. Meanwhile, in some high-power, high-voltage, high-frequency, and high-temperature applications (such as new energy and 5G communications), the performance of silicon-based devices has gradually failed to meet the requirements. Due to the excellent [...]
