New trend in PV cells: rectangular silicon wafers (182R & 210R)
The wide range of innovative rectangular sizes has taken the industry by surprise. When Trina Solar launched its new silicon wafer product "210R" in April 2022, the rectangular silicon wafer was made public for the first time, and the decades-old thinking in the PV industry that silicon wafers should be square was completely dismantled.
Photoluminescence Imaging of Silicon Wafers and Solar Cells …
Photoluminescence imaging is a fast and powerful spatially resolved characterization technique, commonly used for silicon wafers and solar cells. In conventional measurements, homogeneous illumination is used across the sample. In this paper, we present a photoluminescence imaging setup that enables inhomogeneous …
For every solar energy system, a wafer is one of its most important components. This is because a wafer, also called a slice or substrate, is a thin slice of semiconductor, such as crystalline silicon, that is used for the fabrication of integrated circuits and, in the case of photovoltaics, to manufacture solar cells.

Fig. 2 (a) presents QE curves of representative indium gallium arsenide (InGaAs) and Si cameras, while Fig. 2 (b) compares the detected EL flux (φ detect) from c-Si solar cells (with p = 5, 20, and 40) using an InGaAs camera (solid lines) and a Si camera (dotted lines). The detected EL emission from the Si camera is considerably lower than …
High-performance HIT solar cells for thinner silicon wafers
Last year, we updated the world''s highest conversion efficiency, which was previously 22.3%, to 23.0% with a practical-sized HIT solar cell at the R&D stage. We have also been investigating the performance of thinner HIT solar cells using less than 100-μm-thick crystalline Si (c-Si) wafers in order to effectively reduce the production cost.

PV Cells 101: A Primer on the Solar Photovoltaic Cell
To make a silicon solar cell, blocks of crystalline silicon are cut into very thin wafers. The wafer is processed on both sides to separate the electrical charges and form a diode, a device that allows current to flow in only one direction. The diode is sandwiched between metal contacts to let the electrical current easily flow out of the cell.
