RENA BatchTex and InOxSide+ combine perfect shape and best CoO for PERC processing – that’s why RENA Technologies GmbH recently received two large orders for wet process equipment in PERC technology from North American and Indian PV-customers in a double digit millions euro range. The customers` requirements: well-adapted front and back side topologies which are of crucial importance for advanced cell concepts. RENA’s BatchTex and InOxSide+ team up to offer both independent optimization and best match of front and rear sides for best PERC cells efficiencies. RENA’s BatchTex combines ultra-compact tool design with highest throughputs. Together with its proprietary and IPA-free texture additive monoTEX®, it reaches excellent front side reflection with the formation of well-defined, small and uniform pyramids (1 to 3 µm or 2 to 5 µm) within very short process times. This makes rear side smoothing in the InOxSide+ even more effective and further supports advanced rear side passivation performance. With its patented single side etching process and effective smoothing technology, even moderate etch depths of ≤ 4 µm are sufficient to achieve very homogenous back side smoothening. This ensures high reflection of the back side and effective AlOx-passivation and leads, as a result, to excellent PERC cell efficiencies.
