Bifacial sensitive monocrystalline solar modules
The new modules will have efficiency factors that surpass unifacial modules by 10% to 70%-10% when installation is done without additional construction; 70% when reflectors and tracking systems are built. These modules transform direct sunlight as well as light reflected from the natural surface or from specially built reflective elements. The module design is based on patented technology developed by Russian company Solar Wind and research and production company Kvark; the latter-a member-company of the Konti Group.
The main production line for the new modules will begin operating in 2012. Full design capacity should be reached in 2015, bringing production to around 120 MW per year. At that level, the project’s annual sales are forecasted at 11.4 billion rubles. RUSNANO will invest about 2.5 billion rubles in the project. The modules will be manufactured with silicon layers that are 20 nm to 80 nm thick, the ideal thickness for backside light sensitivity; the element itself will have transparency for infrared emission with wavelengths exceeding 1,100 nm. Production costs for these modules are competitive with those for unifacial units. To exploit the advantages of bifacial solar elements fully, the project plans to develop the technology further in the future. It will also reduce costs of production
