The development of cost-effective and highly efficient solar cells is a primary goal of current research activities. In this work we investigate two different metallization concepts based on screen-printing technology that are aimed at achieving incr

In this work, we present a novel fire-through contact (FTC) approach for the formation of local rear contacts for rear surface passivated silicon solar cells. The FTC approach aims at an easy integration of rear surface passivation into typical produ

Thermal silicon oxides are known to very effectively passivate silicon surfaces. Choosing a water vapor ambient instead of a dry oxygen atmosphere increases the oxidation rate by about one order of magnitude and considerably reduces process time and

We present metal wrap through passivated emitter and rear cells (MWT-PERC) on p-type Czochralski silicon (Cz-Si) using advanced metallization approaches. Front surface metallization is performed either with a one-step approach (conventional thick fil

The increase of solar cell efficiency via the implementation of a selective emitter in crystalline silicon solar cells is currently under research and partly in transition into production. The choice of the doping profile underneath the contacts can

We suggest a simplified structure for metal wrap through passivated emitter and rear cells (MWT-PERC). This so called HIP-MWT approach (high-performance MWT) overcomes the need for a structured rear side emitter. With the simplified structure, a sing
