The ultimate efficiency of a silicon photovoltaic cell in converting sunlight to electrical energy is around 20 per cent, and large areas of solar cells are needed to produce useful amounts of power. The search is therefore on for much cheaper cells without too much of a sacrifice in efficiency.
Photovoltaic cells are based on a related phenomenon called the photovoltaic effect, and they convert light directly into electricity. Let’s look at how. Most photovoltaic cells are made of silicon, an element that is at the heart of all modern electronics.
Photovoltaic Cell Defined: A photovoltaic cell, also known as a solar cell, is defined as a device that converts light into electricity using the photovoltaic effect. Working Principle: The solar cell working principle involves converting light energy into electrical energy by separating light-induced charge carriers within a semiconductor.
Most photovoltaic cells are made of silicon, an element that is at the heart of all modern electronics. Silicon is special because of the arrangement of its electrons—it has four out of the possible eight electrons in its outermost shell. This means that it makes perfect covalent bonds with four other silicon atoms, forming a lattice structure.
Developments in the field of photovoltaic technology: the PV cell is the central component of every solar panel; it transforms sunlight into electrical energy. Produced from crystalline silicon, the first generation of PV cells could convert approximately 15% of sunlight into electricity.
Crystalline silicon cells are made of silicon atoms connected to one another to form a crystal lattice. This lattice provides an organized structure that makes conversion of light into electricity more efficient. Solar cells made out of silicon currently provide a combination of high efficiency, low cost, and long lifetime.
