Title and Abstract of the Speech: 

Transparent Photovoltaic Solar Cells and Solar Windows

Şener Oktik

Kadir Has University, Turkey

Almost 55% of solar energy is in the visible region (380nm-780nm). Contributions of ultraviolet (280nm-380nm) and near infrared (780nm-2500nm) regions are   ̴ 4% and ̴ 41% respectively. Thus at the first glance the idea of  “converting solar energy by photovoltaic process via transparent solar cells” might seem to be  a bit  controversial. However, the most cutting-edge research and technological development efforts on new transparent organic photovoltaic (TOPV) solar cell have shown that this new field has  a  great potential to change the game in photovoltaic industries. Combining PV solar energy generation and transparency opens up new applications for variety of industries such as; construction, transport, electronics, display technologies etc. Thus progress in (TOPV) has been exponential and dynamically reviewed (1,2). Recently it is demonstrated that transparent organic photovoltaic cells with  a power conversion efficiency of 10.8% and visible transparency of ∼50% (3).

This work would be concentrated on TOPV and solar windows only.  There is a common belief that when TOPV field reaches to technological and commercial maturity,  solar  windows   would replace  the most of the traditional glass windows  and facades in  commercial and domestic buildings. This would overcome problems related to large land parcels or roof spaces for PV conversion.  It is estimated that the size of the current glass facades in USA is about 5 to 7 billion square meters and installing transparent solar cells on windows and the facades might provide 40% of energy demand.
