A new innovation in renewable energy has been discovered – the photovoltaic transistor, or “solaristor.” It was created in 2018 by Dr. Amador Perez-Tomas and his team at the Catalan Institute of Nanoscience and Nanotechnology (ICN2). These devices can capture solar energy and switch it on and off.
The solaristor works by combining a light-absorbing layer with a semiconductor layer. This design helps it avoid losing energy and boosts its efficiency. It uses thin-film solar cells and special layers to improve its performance.
One big plus of the solaristor is its ability to change how well it conducts electricity. This is thanks to the use of ferroelectric semiconductors. This means it can adjust its performance in big ways.
Solaristors are better than old photodiodes in many ways. They can switch on and off like phototransistors and might even need fewer connections. They could be used in things like photo-sensors, cameras, or displays.
Key Takeaways

Introduction to Photovoltaic Transistors
Photovoltaic transistors are a new technology that combines two important functions in one. They can turn sunlight into electrical power and switch it on and off. This makes them very useful for using solar energy in many ways.
Definition and Overview
Photovoltaic transistors are special devices that can change light into electricity and vice versa. They can work on their own, thanks to this unique ability. This is a big step forward in the world of electronics.
Historical Context
The transistor was invented in the mid-20th century, starting the electronics revolution. But, old transistors need power from outside to work. Photovoltaic transistors change this by using sunlight, opening up a new world of self-powered electronics.
Importance in Renewable Energy
Photovoltaic transistors are key for renewable energy. They help us use solar power in many devices. This is important for reducing our carbon footprint and moving towards cleaner energy.
The International Energy Agency says we now have over 1 terawatt of photovoltaic power worldwide. This is a big step towards using more renewable energy. They predict even more growth in the coming years.

How Photovoltaic Transistors Work
Photovoltaic transistors are special devices that catch sunlight and switch electricity. They use solar transistor technology to control how they turn sunlight into electricity. This lets them switch on and off.
Basic Principles of Operation
These transistors work by catching photons and splitting them into parts. They use a special layer to do this. This layer changes how the device works, letting it control the flow of electricity.
Key Components
The main parts of a photovoltaic transistor are:
- A light-absorbing layer (p-n junction) to catch photons and split them
- A conductivity modulator, often a ferroelectric semiconductor, to change how the device works
- Electrodes to move the parts of the photon around
Energy Conversion Process
The process of turning sunlight into electricity in photovoltaic transistors is complex:
- Photons are caught in the light-absorbing layer, creating pairs of electrons and holes (excitons)
- These pairs are split at the p-n junction
- Electrons and holes move to their electrodes
- The device’s conductivity changes thanks to the ferroelectric semiconductor
- The sunlight is turned into electrical signals for switching and control
This mix of catching sunlight and switching electricity makes photovoltaic transistors very useful. They are key for hybrid energy harvesting devices and saving energy.
