One of the most common strategies in high-efficiency crystalline silicon (c-Si) solar cells for the rear surface is the combination of a dielectric passivation with a point-like contact to the base. In such devices, the ...

This work shows a novel fabrication process of interdigitated back-contacted c-Si(n) solar cells based on laser-doped point contacts. In this approach, all the highly-doped regions have been entirely fabricated through UV ...

In this work we describe a baseline fabrication process of interdigitated-back-contact c-Si(p) solar cells, which combines conventional diffusion oven stages to define base p+ and emitter n+ regions at the backside, with ...

In this work we show small (0.49 cm2) and thin (<70 µm) photovoltaic mini-generators capable of providing open circuit voltages up to 99 V and short circuit currents of 43 µA, achieving a maximum density power of 4.8 mW/cm2. ...

This work explores the use of very thin transparent vanadium oxide films deposited by atomic layer deposition (ALD) technique as hole transport layer for CZTSe solar cells as alternative of opaque molybdenum based contacts. ...
