The group of scientists at the Lausanne Federal in Polytechnic School from Institute of Microengineering, in combination with the others at the Neuchatel, Switzerland in Swiss Center for the Electronics and Microtechnology thinks that they can have conquered the above dilemma.
The group has accounted on their novel procedures to create a twofold junction in the present paper of the journal, Nature Materials. The case comprise in the top cell kind deposition procedure that would encourage inorganic nano-compound to create on the exterior of the unpolished silicon.
The process permitted for the flourishing evidence of liquid perovskite, like in the making of the other two fold junctions. Thus, the need to buff up the silicon is eradicated, and the preferred double-junction is created.
The latest technique has so many advantages: First, it permits for the conventional perovskite evidence steps like spin-coating that can keep building costs under organization. Second, the system enables the silicon coat to retain the standard conformation that is an outline of raised and sharp pyramids at a micrometric scale. Thus, the whole surface area accessible to sunlight is improved, and the indication of the cell can be limited.
The researchers certified this inspiring outcome to the preservation of this silicon micro-texture. It is also declared that the further improvement of the tool would direct to the magic 30 percent efficiency figure.
