Bifacial Solar 2021 – Part 1: Cells & Modules

Since our 2nd TaiyangNews Report Edition on Bifacial Module Technology was published in mid-2018, the technology has rapidly established itself as a mainstream product, reaching a low 2-digit market share both on the cell and module level. Such was the technological progress that we find it impractical to cover the large topic in a single publication. Accordingly, we have split the 2021 edition of our Bifacial Solar Technology Report into two parts – Part 1 discusses the manufacturing side of the technology, essentially covering notable developments in cell and module manufacturing; Part 2, to be published very soon, delves into the application side, focusing on the different parts of bifacial solar systems.
After an introduction, Part 1 of the report has the following structure:

• Chapter 1 provides an overview of the fundamentals and a brief history of bifacial technology.

• Chapter 2 briefly discusses developments associated with bifacial technology especially in the areas of bankability and simulation.

• Chapter 3 discusses and assesses various aspects of processing different bifacial cell technologies, while displaying the top efficiencies announced by the leading players in this field.

• Chapter 4 elaborates on bifacial- specific changes and recent developments related to interconnection and module BOM, such as glass, frames, transparent backsheets and encapsulation materials.

• Chapter 5 discusses the IEC's recently released technical specification (TS) 60904-1-2:2019 with two proposed methods of measuring IV characteristics of bifacial PV.

• Chapter 6 discusses the product characteristics from selected module producers are discussed in detail.

• Chapter 7 provides a market outlook for bifacial solar.

The report also features an interview with  LONGi Solar, a longtime supporter of bifacial technology which has been carrying forward the legacy of bifacial technology through several product generations, including the latest HiMO5.
