Solar Photovoltaic Photoresist

Are flexible and lightweight photovoltaics the future of solar energy?

The recent surge in solar energy utilization to achieve net-zero carbon emissions has amplified the demands for the development of flexible and lightweight photovoltaics (PVs) that can be installed in locations where traditional silicon-based solar cells are impractical, such as curved surfaces or in areas with limited weight-bearing capacity.

What is a negative photoresist?

Specifically, the negative photoresist is mainly composed of cross-linked gelatin, abbreviated to Gel-NP. It was found that the Gel-NP can effectively suppress the pinholes of the CdTe layer and reduce the shunt path of the solar cell.

How is a microstructured photoresist developed?

The resist was developed by immersing the wafer into ma-D 533/S photoresist developer for 75 s; the wafer was then rinsed in H 2 O for 30 s (twice) and blow-dried using a nitrogen gun. The microstructured photoresist was used as a reactive ion etching (RIE) mask in an Oxford PlasmaPro Cobra RIE.

Does silica solar module glass enhance passive radiative cooling?

Here, we design a hexagonal array of cylinders etched into the top surface of silica solar module glass to enhance passive radiative cooling. Multipolar Mie-like resonances in the cylinders are shown to cause antireflection effects in the infrared, which results in enhanced infrared emissivity.

How can a silicon solar module improve passive radiative cooling (PRC) power?

This difference is explained by light trapping: light is scattered by the microcylinders and trapped in the silica substrate by total internal reflection. This work shows that the passive radiative cooling (PRC) power of a silicon solar module can be enhanced by placing an array of microcylinders on top of the module glass.

Can lift-off process-based F-pctscs be used in a vehicle-integrated solar system?

This approach demonstrates the potential of lift-off, process-based F-PCTSCs, advancing flexible tandem solar cells toward practical uses in building- and vehicle-integrated PV, portable electronics, and aerospace.
