Semiconductors are called that due to their elemental makeup, not because current is or is not flowing through them. Basically, semiconductors have a "good" number of electrons in their outer ring (valence electrons), making them (as my chemistry professor said...) "fat and happy" as they are.
Silicon is an example. It has 4 valence electrons, so it is happy. Elements in the third row of the Periodic Table want to have 0 (actually 8 in row 2), 4, or 8 valence electrons, and will try to steal or give away electrons to get there. This "stealing" or "giving away" causes elements to group together into molecules, but it also can cause an electrical charge build up if you can get enough atoms of one element that want electrons or want to give away electrons in a specific area.
This is why semiconductors are so important for modern circuits. Since they're "fat and happy", they don't influence whatever the designer is trying to build; they act as an unbiased base to build on.
To create electrical circuits, silicon is used as the foundation, and specific locations of the silicon disk have elements with (usually) 3 or 5 valence electrons placed onto it (called "doping"). This creates electrical potentials across the silicon; when put together in specific ways, this forms diodes, transistors, micro capacitors, exc.
The purpose of semiconductors is to control the amount of conduction, not the amount of insulation.

semiconductors will be having some charged particles but for practical purpose the free charges should be available in abundant quantity. so in order to increase the charge particles number we add some impurity to these semiconductors . this process is called doping

A substance that carries electricity under certain circumstances but not under others is called a semiconductor. Semiconductors have properties that allow them to conduct electricity under specific conditions, such as when they are doped with impurities or when they are subjected to heat or light. Common examples include silicon and germanium, which are widely used in electronic devices. Their ability to switch between conducting and non-conducting states makes them essential for modern electronics.
Metalloids when used is electronics are called semiconductors.
Conductor are materials that conduct electricity. There are also semiconductors, which conduct electricity but not as well, and superconductors, which conduct electricity without resistance when very cold.

The term for flow performed by electricity is called "electric current." It is the movement of electrically charged particles, such as electrons, through a conducting material.
An element that exhibits both metallic and non-metallic characteristics is called a metalloid. For example, silicon is a metalloid; it has a shiny appearance like metals but is brittle and poor at conducting electricity compared to metals. Metalloids typically have intermediate properties that make them useful in various applications, including semiconductors in electronics.

The device that uses semiconductors to produce electricity from solar energy is called a solar cell, or photovoltaic (PV) cell. These cells convert sunlight directly into electricity through the photovoltaic effect, where semiconductor materials generate an electric current when exposed to light. Typically made from silicon, solar cells are the fundamental building blocks of solar panels used in various applications, from residential rooftops to large solar farms.
