New Fraunhofer Solar Cell Stringer Uses Adhesives For 2% Boost

An R&D team at Fraunhofer ISE has unveiled a new solar cell stringing machine that can boost cell performance 2% by using electrically conductive adhesives to fix solar cells to a foil substrate in a shingled pattern. The process reduces the number of manufacturing steps that soldering a connective ribbon would require, and imparts more efficient cell performance in several incremental ways.

How Efficient Will Solar PV Be In The Future? 10-Year Predictions For The Industry

If you were to walk into a solar store and purchase some of their best-selling PV panels, it is likely that their solar irradiance-to-electricity conversion efficiency would be around 17%. This is the typical efficiency (Fraunhofer ISE Photovoltaics Report, 2017) of the top-selling PV product, a multi-crystalline silicon panel. This means that for a typical panel, 17% of all incident solar energy is converted directly to usable electricity. This is quite impressive for a device that has no moving parts and can generate power at the location where the electricity is required (no transmission losses). It is no wonder that PV is already one of the cheapest power technologies available.

REC Solar Switching Over All Production Capacity To Half-Cut PERC Cell Technology

REC Solar is switching all of its manufacturing/production capacity at its manufacturing plant in Tuas, Singapore, over to its half-cut PERC cell technology, according to recent reports. The company’s TwinPeak series of solar photovoltaic (PV) modules features the aforementioned technology. The production conversion will run around SG$200 million (~$182 million), … [continued]

Meyer Burger Wins Order For Passivated Emitter Rear Cell Technology Equal To 2.5 GW Of…

The photovoltaics, semiconductors, and optoelectronics company Meyer Burger recently won a CHF38 million (US$40.9 million) order for passivated emitter rear cell (PERC) technology equivalent to 2.5 gigawatts (GW) of annual capacity. While the deal is certainly a big and important one, the customer involved hasn’t been publicly revealed — though Meyer Burger did … [continued]
