一、光电技术简介 光电技术是利用半导体把太阳能转化为电能的技术,它主要是通过不同类型的光电电池来实现的,光电电池是光电系统的最基本的部分。光电电池产生的电为直流电,通常在光电阵列的输出口端安装一个电流逆变器,以便把电流转换为与当地所供电流的电压和频率相匹配的交流电。因此,光电系统可以与当地的公用电网联网,并与公用电网的电力形成互补。白天,当太阳辐射强度大的时候,它所产生的电力可能超过建筑物本身所需用的电力。这时,它可将多余的电力输送给公用电网,或将多余的
I. Optoelectronic Technology Introduction Optoelectronic technology is a technology that uses semiconductors to convert solar energy into electrical energy. It is mainly realized through different types of photovoltaic cells. Photovoltaic cells are the most basic part of photovoltaic systems. Photovoltaic cells generate electricity as direct current, and a current inverter is usually installed at the output end of the photovoltaic array to convert the current to an alternating current that matches the voltage and frequency of the local supply current. Therefore, the photovoltaic system can be networked with the local public power grid and complement the power of the public power grid. During the day, when the solar radiation intensity is high, it may generate more electricity than the building itself needs. At this time, it can send excess power to the utility grid, or it will superfluous
