Laser sintering of photoelectrode layers for Dye Solar Cell technology

Scanning laser processing has become a useful and often used tool in thin film solar cell industries, since it enables precise, low cost, non-contact and highly automated fabrication processes such as scribing, patterning, marking, edge deletion, local melting and sintering. Dye solar cells (DSCs) are electrochemical photovoltaic devices representing an attractive technology for large area solar energy conversion since they utilize relatively cheap materials and simple manufacturing processes often "borrowed" from the printing industry. In this paper we show successful application of laser processing to this technology.
