The operation of solar cells is based on the photovoltaic effect that is the direct conversion of incident light into electricity by a p – n (or p – i – n) junction semiconductor device. To guide the reader, let us first introduce the terminology used and treat the factors determining the power conversion efficiency.
While the development of solar cells for spacecraft has focused on the improvement of power conversion, cost reduction became the primary goal in research and development of terrestrial solar cells to make the cost of energy generation comparable to that of electricity generated by power plants based on fossil fuels.
In the case of the substrate configuration, solar cells are fabricated from the back to the front, and the deposition starts from the back reflector and is finished with a TCO layer. For some specific applications, the use of lightweight, unbreakable substrates, such as stainless steel, polyimide or PET (polyethylene terephtalate) is advantageous.
Over 50 years passed from the first practical use of solar cells, monolithical Si solar cells powered instruments on board the Vanguard I satellite launched in 1958 . Initially, the space applications were the major driving force for development of photovoltaic (PV) devices.
An antireflection coating (usually titanium dioxide or silicon nitride) is deposited on the top contact fingers to complete the device structure. Due to its robust process technology and high throughput, screen-printing is the most common technique for metallization of today’s industrial solar cells.
Regarding the material choice, compound semiconductors from the III–V family are the most attractive materials for high-efficiency solar cells owing to the wide range of achievable direct bandgaps and long minority-carrier lifetimes.
