You seem to be asking for a personal tutorial, which would require someone to spend a lot of time and effort to write.
There is a great deal of information available on the web that will explain the comparative merits of the many types of photovoltaic cells. You spend some time and effort finding and reading that information and then come back with some specific questions.

 

At Sosnovice 2013 conference "Measurement" (Slovakia) referats I remember one excellent where researchers tried to dig-up why cheap Cheeneeze panels for 30 USD/m2 crushes at first winter while 700 USD/m2 expensive German made works well even 30 years long.
The thousands of tests was led and it was shown that panel itself differs with nothing. The same chemistry, same purity, same technology etc etc. The only difference was that bad panels had embalage of chocklade paper thick, while German had massive 0,7 mm and 1 mm thick. When wind, rain, warmth and cold was coming over in the raw, the thin panel was changing the size and crystall got tyred up to micro-cracking. But thick panel instead, was strongly kept by embalage thus the crystall got no a large expansion stress.

\The receipt - buy the cheap and construct an embalage in the DIY way.
