Photovoltaic solar cells and modules as the source of electricity in the world and their future in Poland

One of the methods leading to C02 reduction in Poland is the substitution of fossil fuels by renewable energy sources. Direct use of energy from renewable energy sources causes a significant reduction in Greenhouse Gases (GHGs) emissions to the atmosphere. Photovoltaic (PV) systems generating electricity from solar radiation are foreseen as a technological option significantly contributing to the sustainable energy supply due to continuous technological progress and drastic cost reduction. In this paper the progress that has been made all around the world in the last years and work that needs to be done, especially in the European countries and in Poland was presented. Poland should follow the example of the industrially developed world, where investments in PV systems continue to grow, with most interest focused on the great potential for PV in human settlements. The photovoltaic technology offers many social and economic benefits for users in Poland. The author points out the need to create a long-term strategy for implementing PV systems and neces sary changes in the legislation system. The photovoltaic potential of our region from the geographical location point of view has been presented.
