Semiconductor equipment supplier, Novellus Systems is developing what it describes as conformal film deposition (CFD) technology, an atomic layer deposition process to grow conformal metal oxide and metal nitride dipole layers in the PV cells. Collaboration is being undertaken with the University of South Florida (USF), to study the precise engineering of solar cell interfaces via a National Science Foundation (NSF) grant.
Pushing the boundaries of conventional silicon solar cell technology, while offering a low-cost production approach, took another step forward, according to R&D organisation, imec. In conjunction with its industrial affiliates, researchers have developed a small-area (2x2 cm2) - interdigitated back-contact (IBC) silicon solar cells that has demonstrated a conversion efficiency of 23.3%. Work will now focus on developing a large-area and production viable cell and process steps.
Orders from Canada and Azerbaijan for Vitrododi solar glass washers are now being built at a Rimas factory in Holland for Rimas PV manufacturing lines. Vitrododi Solar was acquired by Rimas in July, 2011.
Third quarter results from Hanwha SolarOne echoed pricing pressure and weak demand, especially from Germany that led to margin pressure, inventory write downs and losses. Hanwha SolarOne reported US$225.4 million in revenue, a decrease of 20.1% from 2Q11 when revenue reached US$277.1 million. The company recorded a non-cash inventory write-down of US$30.6 million and a net loss of US$46.4 million.
Kaneka Corporation has signed a licensing agreement with Q-Cells for two patents related to a heat insulator spacer for solar cell based modules. The patents, EP 1009037 and US6300555 cover European and US patents owned by Kaneka.
After a record revenue financial year, Applied Materials is experiencing a significant reduction in equipment orders and revenue from PV manufacturing customers. Though cancellations were minimal, backlog decreased by 26% to US$2.4 billion, of which 14% is within its EES division, which includes PV equipment. Management expects PV related global CapEx to at fall by at least 50% in 2012 as manufacturers combat massive overcapacity and focus on cell efficiency improvements and technology buys.
Continuous pressure on pricing as demand remains weak has further impacted PV product sales and profits at Sunways. Consolidated sales declined by €35.0 million to €23.3 million, compared to the same quarter a year ago when sales reached €58.3 million. Lower cell manufacturing utilization, inventory write-downs on falling ASPs meant Sunways reported losses € 6.3 million an a negative operating result (EBIT) of €11.8 million in the third quarter.
Indeotec has received the first order and down payment for its Octopus II plasma processing tool. Octopus II was first unveiled at PVSEC in Hamburg and is the successor to Indeotec’s popular Octopus I. The new tool measures 300mm x 400mm and is characterized by several PECVD, PVD, heating and customised chambers around a central unit.
After eleven years of research and development, Sharp Corporation has achieved the world’s highest solar cell conversion efficiency of 36.9% using a triple-junction compound solar cell in which the solar cell has a stacked three-layer structure. Measurement of this value, which sets a new record for the world’s highest non-concentrating conversion efficiency, was confirmed at the National Institute of Advanced Industrial Science and Technology (AIST).
German manufacturer Singulus Technologies has received an order for its Singular PECVD tool, a coating tool for the application of ARCs on crystalline silicon solar cells, from the Solar Energy Research Institute of Singapore (SERIS). The SINGULAR is part of a multi-million dollar project headed by SERIS focusing on silicon wafer heterojunction solar cells and their mass production.
