2.Due to dopant migration, build-in electric field exists in the device.There is open-circuit photoresponse, the detector can operate in photovoltaic mode.
件掺杂迁移迁移的影响而存在内建电场,使得件有开路响应,存在光致电压模式。
3.Photovoltaic parts: storage cell, cell charger, controller, transverter, recorder, inverter, monitor, mounting system, tracking system, solar cable etc.
