National policy on thin-film solar power generation

What are the new thin-film PV technologies?

With intense R&D efforts in materials science, several new thin-film PV technologies have emerged that have high potential, including perovksite solar cells, Copper zinc tin sulfide (Cu 2 ZnSnS 4, CZTS) solar cells, and quantum dot (QD) solar cells. 6.1. Perovskite materials

What are thin film solar cells?

Thin film solar cells are favorable because of their minimum material usage and rising efficiencies. The three major thin film solar cell technologies include amorphous silicon (α-Si), copper indium gallium selenide (CIGS), and cadmium telluride (CdTe).

Are CIGS and CdTe the future of thin film solar cells?

CIGS and CdTe hold the greatest promise for the future of thin film. Longevity, reliability, consumer confidence and greater investments must be established before thin film solar cells are explored on building integrated photovoltaic systems. 1. Introduction

What are the emerging thin film technologies?

Section 6 highlights emerging next generation thin film technologies such as Perovskite materials, Copper zinc tin sulfide (CZTS), and quantum dots (QD). In Section 7 we draw conclusions and highlight major accomplishments and developments based on the review.

What is a third type of photovoltaic technology?

A third type of photovoltaic technology is named after the elements that compose them. III-V solar cells are mainly constructed from elements in Group III—e.g., gallium and indium—and Group V—e.g., arsenic and antimony—of the periodic table. These solar cells are generally much more expensive to manufacture than other technologies.

Why should solar PV be harmonised?

• Total life cycle GHG emissions from solar PV systems are similar to other renewables and nuclear energy, and much lower than coal. Harmonization increases the precision of life cycle GHG emission estimates for c-Si and TF PV, reducing variability in the interquartile range (75th minus 25th percentile value) by 65%.
