Systems’ latest photovoltaic modules use an innovative technology known as “thin film”. Thin film technology uses far less active material than conventional panel construction technologies.
Given their low cost and stylish appearance, CIS modules are frequently used in photovoltaic systems integrated in building façades. CIS panels come in a range of colours, and can even be screen printed and made semi-transparent to create attractive urban décor. They can therefore be prominent elements of architecture rather than having to be hidden away.
The CIS (copper, indium, selenium) semiconductor is uniformly black in colour. Compared to other common technologies, CIS photovoltaic panels offer higher energy outputs in conditions of diffused light, partial shading and fluctuating temperature.
The main benefits of CIS photovoltaic cells are low cost and an easily automated production process. CIS photovoltaic panels can therefore be manufactured in large volumes.
They are also extremely reliable and efficient and boast good electrical characteristics.
Since CIS photovoltaic cells first appeared in 1988, they have been developed to levels of efficiency similar to those of silicon cells. An American research institute, National Renewable Laboratories, has recorded efficiencies of up to 18.8% with glass substrates.
