A new solar cell over 26 per cent of efficiency

various experiments with solar technology have soared beyond the efficiency of cells 40 percent however, in what refers to conventional silicon designs is estimated the theoretical ceiling of a 29 percent . Any option that exceeds 20 percent is ideal for commercial applications, but the Japanese company Kaneka has just presented a new solar cell can achieve an efficiency of the 26.6 percent thus setting a new record.

one of the most delicate and complicated the adoption of solar energy for personal use is the cost, especially when we talk about the process of installation. Users need to know with precision long will take them to recover the total investment and a good starting point in the reduction of that factor is to obtain panels with better efficiency. Experts suggest an upper limit for the cells of Silicon in the order of 29 percent (29.1-29.4) . Technically was already crossed but those prototypes require designs and much more exotic materials, which makes breaking the cost-benefit ratio. The market will look for squeezing all the options in Silicon, and latest innovations lead US to Japan, where the Kaneka Corporation just break a new record.

each won point of efficiency helps reduce the costs of energy solar

your new solar cell of 180.4 square centimetres records efficiency 26.6 percent locating a point above the previous mark (que estaba en manos de Panasonic) . Initially, the cell had achieved a 26.3 per cent but a series of optimizations allowed developers to remove this additional 0.3 per cent. The key behind this cell is a proprietary technique of heterojuncion that minimizes the energy bands, and this is compounded by a series of low-resistance electrodes located on the back of the cell, which help to collect a larger amount of photons. The manufacture of the cell is compatible with industrial methods available, therefore their improvements should not miss in a laboratory.

even so, must be patient . We need more work and additional tests before the cells can give way to a solar panel ready to be installed. Kaneka research was funded by the Japanese Government through its agency NEDO, and the next goal is continue lowering costs.
