Xinchuang the leader in photovoltaic energy storage silicon wafers

What is shuangliang eco-energy's production capacity?

Currently, the company’s 50GW wafer capacity is compatible with production of all sizes including 210mm. According to Shuangliang Eco-energy’s mono silicon wafer business planning, it is expected to have a production capacity of more than 40GW by the end of 2022 with the progression of various projects.

How can we improve the flexibility of silicon wafers?

This fact enabled us to improve the flexibility of silicon wafers by blunting the pyramidal structure in the marginal regions. This edge-blunting technique enables commercial production of large-scale (>240 cm2), high-efficiency (>24%) silicon solar cells that can be rolled similarly to a sheet of paper.

What was the market share of directionally solidified silicon wafers in 2022?

The market share of directionally solidified silicon wafers was approximately 3% in 2022, despite predictions of 2022 market shares of 10%–45%. This highlights that the industry shifted toward monocrystalline silicon much faster and to a broader monocrystalline silicon usage than predicted.

How did shuangliang Eco-Energy perform in the first three quarters?

Shuangliang Eco-energy achieved a total operating revenue of RMB8.75 billion (US$1.2 billion) in the first three quarters, up by 285.7% year-on-year. Net profit attributable to the parent company reached RMB830 million (US$113.56 million), a year-on-year increase of 368.8%. Both performances hit record highs for the company.

Are n-type monocrystalline phosphorus wafers a good choice for high-efficiency solar cells?

Once research for terrestrial PV applications began, and through the early days of industrial manufacturing, n-type monocrystalline wafers doped with phosphorus were the wafer of choice for high-efficiency stable solar cells, due to their inherent immunity to BO-LID.

Why do p-type silicon wafers have a higher recombination sensitivity?

This is related to the greater sensitivity of p-type silicon wafers to common metal point defects such as interstitial iron and the susceptibility of boron-doped (B-doped) Cz-grown silicon to BO-LID. 76 The quality of the bulk wafer becomes more critical to cell performance once other recombination mechanisms (e.g., surface-related) are minimized.
