The Japanese are always wary of the nuclear issue. After Hiroshima and Nagasaki, they can understand. In the 60's and even 70's personal dosimeter was almost mandatory attribute of the Japanese. Nevertheless, in the country's nuclear power factory were built, and everything went more or less well to the latest accident at the Fukushima-1 nuclear power factory. After the events that became a consequence of the earthquake and subsequent tsunami, the country has accelerated the transition to alternative energy.
The basic problem of solar (PV) inverters - a relatively low efficiency. The mass efficiency of solar panels is approaching the mark of 20%. So, last fall, Panasonic has started mass production of solar panels with an efficiency of 19.7%. It is worth adding to the rapid degradation of semiconductors panel that limits the efficient operation of the panels five years or less.
Until recently, the record value of the efficiency of solar panels was 22.8% in Panasonic's laboratories. Recently the company announced the establishment of a new record on the transformation of solar energy into electricity. Researchers Panasonic created a photovoltaic cell with an efficiency of 23.8%. photocell cell was integral and consists of several layers of crystalline and amorphous silicon. There was also changed the structure of the conductive wires, which were moved to the back of the cells that remove excess shadow over the active area of the panel.
