The same solar cells should be inexpensive and have the ability to connect to large batteries. The most widely used become the silicon solar cells, due to well-developed technology, relative cheapness of raw materials and good characteristics of silicon in terms of direct conversion of solar energy into electricity.
Solar cells based on crystalline silicon have a fairly high cost, primarily associated with the expensive operation of cutting silicon ingots into plates. Silicon solar cell has a theoretical marginal efficiency of about 30% under standard conditions (1 kW / m2 illumination, + 25 ° C, air mass AM1,5).
There has been a considerable effort in the past for proposing many different solutions for silicon based CPV solar cells , , , , . By using fabrication procedure running in research lab it was demonstrated that back-contact cell schemes were able to improve efficiency up to 27% at about 100 suns .
In this work we have presented a small-area silicon solar cell, designed for operation under medium concentration conditions and based on a simplified CMOS-like single-side process. The fabrication technology, the front grid contact optimization, the experimental characterization and the modeling of the solar cell have been described in detail.
In practice, as ARC for silicon solar cells are most commonly used titanium oxide film or silicon nitride, the last one being is increasingly preferred. Silicon nitride is usually applied by PECVD, i. e. by accelerated plasma chemical deposition from a gaseous phase, in special tube furnaces.
