For fabrication of a high-quality PV cell, it is very important to get good charge extraction scheme. The charge carriers obtained out of photo effect should be effectively shifted from the absorber material to the external provided terminals and in another hand minimalizing the recombination. Contacts are selected on the basis of suitable carrier which could help in easy transport of one at a time, electron/hole, while keeping the other contact blocked. In practice, there are different combinations of electron and hole which can be implemented through the use of membranes on the wafer of silicon, obtaining various types of c-Si-based PV cells.
