任何物體受到光波的照射時,只要光波的能量超過物體中電子脱出物體所需的功時,便有電子由物體中跑出來,所以光電效應在任何物體上都會發生。但是要觀察或測量光電效應,必須利用特殊的裝置。這些裝置的基本原理都是利用電路中單向導電的性質,使光電效應所發生的電子流,只能向電路的一個方向流動,再使其通過電流計或放大的裝置来觀測它。常用的觀察光電效應的仪器有真空光電管及固體光電池兩類。這兩類儀器各有其優點,目前國內尚未開始製造。今介紹利用國產的氧化銅整流器中的整流片製成固體光電池的方法,以備在教學中作演示光電效應實驗或學生們作光電效應測量實驗時應用。通過固體光電池的實驗,不僅使學生們了解如何在自動化工業生產中利用光電池,同時可以使學生們初步地認識到半導體的性質。氧化銅固體光電池與氧化銅整流片的基本
When any object is exposed to a light wave, as long as the energy of the light wave exceeds the work required by the electron projectile in the object, electrons will be ejected from the object, so the photoelectric effect will occur on any object. However, to observe or measure the photoelectric effect, we must use special devices. The basic principle of these devices is to make use of the unidirectional conductivity of the circuit, so that the electron flow generated by the photoelectric effect can only flow in one direction of the circuit and then be observed by an ammeter or an amplifying device. Common observation photoelectric effect of the instrument has a vacuum photocell and solid photocell two types. These two types of instruments have their own advantages, the current domestic has not yet started manufacturing. This article describes the use of domestic copper oxide rectifier rectifier film made of solid photovoltaic cells in preparation for the teaching demonstration photoelectric effect experiment or students for the photoelectric effect measurement experiment application. Experiments with solid-state photovoltaic cells not only enabled students to understand how to use photovoltaic cells in automated industrial production, but also enable students to initially understand the nature of semiconductors.
