The market-dominating silicon solar cell is a pn junction with a thin highly-doped n-layer, the front, light-admitting electrode, on a p-type substrate. Light entering at the n-layer is partially absorbed in the diffusion layer adjacent to the depletion region that separates the photocharges, as well as in the p-layer behind the junction.
Silicon-based solar cells are an important field for the development of the photovoltaic industry. The grid electrode on the front surface of the traditional silicon solar cell causes shading loss.
The device structure of a silicon solar cell is based on the concept of a p-n junction, for which dopant atoms such as phosphorus and boron are introduced into intrinsic silicon for preparing n- or p-type silicon, respectively. A simplified schematic cross-section of a commercial mono-crystalline silicon solar cell is shown in Fig. 2.
A solar cell is basically a p-n junction diode. Solar cells are a form of photoelectric cell, defined as a device whose electrical characteristics – such as current, voltage, or resistance – vary when exposed to light. Individual solar cells can be combined to form modules commonly known as solar panels.
Silicon solar cells are the most broadly utilized of all solar cell due to their high photo-conversion efficiency even as single junction photovoltaic devices. Besides, the high relative abundance of silicon drives their preference in the PV landscape.
The solar cell efficiency of crystalline silicon is limited by three loss mechanisms: optical losses, carrier losses and electrical losses. The back contact silicon solar cell is another high efficiency device, where all the metallisation on the front surface is removed.
In the course of the last decade, photovoltaics (PV) have become the cheapest energy in many locations in the world. 1 The power conversion efficiency (PCE) of solar cells is one important factor contributing …
