The buried contact solar cell is a high efficiency commercial solar cell technology based on a plated metal contact inside a laser-formed groove.
The buried contact technology overcomes many of the disadvantages associated with screen-printed contacts and this allows buried contact solar cell to have performance up to 25% better than commercial screen-printed solar cells. A schematic of a buried contact solar cell is shown in the figure below.
A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode.
Photovoltaic (PV) cells, commonly known as solar cells, are the building blocks of solar panels that convert sunlight directly into electricity. Understanding the construction and working principles of PV cells is essential for appreciating how solar energy systems harness renewable energy.
Construction Details: Solar cells consist of a thin p-type semiconductor layer atop a thicker n-type layer, with electrodes that allow light penetration and energy capture.
Photovoltaic panels are made up of several groups of photoelectric cells connected to each other. Each group of solar cells forms a network of photovoltaic cells connected in a series of electrical circuits to increase the output voltage.
