A solar cell is any device that converts the energy from the sun into electricity through the photovoltaic effect. Solar PV panels are made up of a group of these solar cells which collectively capture sunlight and convert it into solar power.
When researching solar cells you may also come across the term ‘high-efficiency solar cells’ which are a class of solar cells that are used in solar power systems which can generate more electricity per cost of the generation. With the cost of Solar PV electricity being historically high, the two main aims to make cells more accessible are to decrease their cost per unit area or increase the efficiency.
Monocrystalline cells, cut from a single crystal of silicon, are the most efficient cells currently in solar panels used to power homes, however they are the most expensive to produce
