In electronics, a transimpedance amplifier (TIA) is a current to voltage converter, almost exclusively implemented with one or more operational amplifiers (opamps). The TIA can be used to amplify the current output of Geiger–Müller tubes, photo multiplier tubes, accelerometers, photodetectors and other sensors (that are modeled well as a current source) into a usable voltage.

Each material has a threshold frequency, a minimum energy level the incoming light must meet before it can knock electrons loose. They work by exploiting a fundamental property of certain materials: when photons (particles of light) strike their surface, they either knock electrons free or change the material's ability to conduct current. This simple principle powers everything from solar panels on rooftops to the automatic. Solar Cell Definition: A solar cell (also known as a photovoltaic cell) is an electrical device that transforms light energy directly into electrical energy using the photovoltaic effect.
