California-based company Solar Junction set a new record efficiency solar cell – 43,5%. This record beats all other previous records and accomplishments of famous companies and laboratories. The Solar Junction company uses a fairly old technology of multi-transient cells, which are used in space vehicles and for electricity generation in desert areas. Their design includes multiple layers of photovoltaic cells laminated on a substrate of gallium arsenide.This breakthrough is expected to attract companies that produce concentration solar photovoltaic collectors. Solar Junction is seeking to expand its production to 250 megawatts and run a business selling solar cells a year.
