Life cycle inventories (LCIs) and life cycle assessments (LCAs) of photovoltaic (PV) modules and their components focus on the operations of PV factories, but the factories and industrial site product and construction stages are either not or only pa

Abstract Fine line screen printing for solar cell metallization is one of the most critical steps in the entire production chain of solar cells, facing the challenge of providing a conductive grid with a minimum amount of resource consumption at an e

We investigate different postseparation process routes for silicon heterojunction (SHJ) half solar cells, separated by thermal laser separation. SHJ half cells with and without aluminum oxide (Al 2 O 3 ) deposition as edge passivation layer undergo d

This article investigates thermal laser separation (TLS) on p -type Czochralski-grown silicon (Cz-Si) passivated emitter and rear cells (PERC) and n -type Cz-Si heterojunction (SHJ) solar cells. The TLS comprises of two laser-based processes: the cra

We present results in post-metallization “passivated edge technology” (PET) and its application on bifacial p-type silicon shingle solar cells. Host cells (full cells with shingle metallization layout after contact firing) separated by either the

In this contribution, atmospheric pressure dry etching (ADE) texture is integrated into a passivated emitter and rear cell (PERC) process. In order to make the texture suitable for the solar cell processing, two post-etching processes (inverted pyram

Laser diffusion from PECVD layers can result in the incorporation of impurities like nitrogen into crystalline silicon. It is shown that the nitrogen can have a significant influence on the laser doping process. The incorporated nitrogen can affect t
