Can perovskite photovoltaic technology be used in pulp & paper industry?

This research can not only provide high-performance green solutions for the perovskite photovoltaic field but is also expected to open up new, high-value-added application areas for the pulp and paper industry. Bleached chemical softwood pulp was obtained through the sulfate pulping process.

How are p i n perovskite solar cells made?

fabrication of p –i –n perovskite solar cells. All layers were prepared by vacuum sublimation of the corresponding inor- ganic or organic materials in high-vacuum chambers. A scheme of the device structure is reported in Fig. 1a.

How do p i n solar cells perform?

function on the performance of p –i –n solar cells, where the electron transport layer is deposited on top of the perovskite and before the metal electrode. We compared the performance of the devices using BCP, Liq or combinations of them, using either Ag or Ba as the top electrode.

Why is haze paper important for photovoltaic materials?

Haze, one of the unique properties of paper, is the effect of light scattering in the cellulose fiber matrix, which can increase the area of light utilization. Therefore, high transmittance and high haze paper can maximize the light utilization efficiency of photovoltaic materials.

How to make ohmic contacts in polymeric solar cells?

In inorganic semiconductor devices, differential doping is a common approach to make ohmic contacts. However, it is difficult to implement this approach in polymeric solar cells and a different strategy is used to extract charge carriers from the photoactive layer.

Can UV-blocking extend the lifespan of functional cellulose paper?

However, the inherent instability under UV illumination limits their practical applications. In this work, we developed a new approach to fabricate functional cellulose paper (FTH paper) with high transparency, high haze, and UV-blocking, which can be used to extend the lifespan of PSCs.
