Project summary:

In-line processing of n+/p and p/p+ junction systems for cheap photovoltaic module production – InlinePV

Although the sun is the cheapest source of energy on the Earth, the conversion of its light into electricity is still one of the most expensive. The application of photovoltaic (PV) cells/modules to convert sun light is one of several ways to lower fossil energy consumption, decrease CO2 emission and diversify energy sources. Unfortunately, the PV module production costs still limit utilization of this energy source in common daily use. Therefore, we propose a solution that can lead to simplification of the PV cell fabrication resulting in final decrease of their costs and thus, to lowering the financial barrier for all. Nowadays, the n+/p and p/p+ junctions formation, which is the basic Si solar cell part, is performed in separate processing steps. In this project we are going to modify the junction formation methodology that can be applied in-line. Moreover, the n+/p junction formation with the use of liquids instead of gaseous and toxic PClO3 allows construction of simple and cheaper production systems. The p/p+ junction can be also formed from liquid or steady sources replacing conventional paste application. Such approach should significantly simplify PV cell production due to shortening of the processing time and lower costs of technological procedures. Additionally, combining the fast texturization by catalytic nanoparticles application with the plasmonic nanoparticle systems deposited on the cell surface should increase the cell efficiency. The PV cells and modules of higher efficiencies, which can be produced at lower fabrication costs than the present ones, will be the main outcome of the proposed project.
