1. Introduction

Recently, the demand of solar cells has rapidly been growing with an increasing social inter­est in photovoltaic energy. Improving the energy conversion efficiency of solar cells by de­veloping the technology and concepts must be increasingly extended as one of the key components in our future global energy supplement, but, the main problem of photovoltaic modules are their rather high production and energy cost.

Third generation solar cell is an alternative type of the promising device, which aims to ach­ieve high-efficiency devices with low cost in comparison with expensive first generation so­lar cells and low-efficiency seco...

Over the last decade, PV technology has shown the potential to become a major source of power generation for the world – with robust and continuous growth even during times of financial and economic crisis. That growth is expected to continue in the years ahead as worldwide awareness of the advantages of PV increases. At the end of 2009, the world’s PV cumulative installed capacity was approaching 23 GW. One year later it was 40 GW. In 2011, more than 69 GW are installed globally and could produce 85 TWh of electricity every year. This energy volume is sufficient to cover the annual power supply needs of over 20 million households. PV is now, after hydro and wind power, the third most important renewable energy in terms of globally installed capacity...
