Even though the passivated emitter and rear cell (PERC) concept was introduced as a
laboratory-type solar cell in 1989, it took 25 years to transfer this concept into industrial mass …

Thanks to fast learning and sustained growth, solar photovoltaics (PV) is today a highly cost-
competitive technology, ready to contribute substantially to CO 2 emissions mitigation …

In recent years, the scientific research into photovoltaic (PV) technology has focused on the

Perovskite solar cells have now become the most efficient of all multicrystalline thin film
photovoltaic technologies, reaching 25.2% in 2019. This outstanding figure of merit has only …

Crystalline silicon (c-Si) heterojunction (HJT) solar cells are one of the promising
technologies for next-generation industrial high-efficiency silicon solar cells, and many …

Silicon heterojunction (SHJ) solar cells are attracting attention as high-efficiency Si solar
cells. The features of SHJ solar cells are:(1) high efficiency,(2) good temperature …

This paper presents the history of the development of heterojunction silicon solar cells from
the first studies of the amorphous silicon/crystalline silicon junction to the creation of HJT …

In this work, we present results on various low-temperature approaches for the metallization
and interconnection of high-efficiency solar cells as silicon heterojunction (SHJ) or …

In the last decade and longer, photovoltaic module manufacturers have experienced a
rapidly growing market along with a dramatic decrease in module prices. Such cost …

This paper reviews recent progress made at CSEM on the development of low-temperature
