U.S. National Renewable Energy Laboratory (NREL) has developed an automated robot can process thin film solar cells, and can analyze and test the performance of the battery cell defect. The laboratory results to industrial efficiency and precision are combined to produce highly efficient solar cells.
NREL developed the robot can process thin film solar cell, battery and can detect defects.
The core of the system is a central Chuandi robot can be put into a completely sealed metal vacuum processing room, and then deposited on the surface nano-thin layer of chemical material, processed into semiconductor. Semiconductor completed, the robot can analyze the technical failure, measurement of light absorption, and then prepare for the next batch of six metal plates.
This robot can just about 35 minutes in the six square inches of glass, plastic plates or metal surface processed silicon.
U.S. National Renewable Energy Laboratory (NREL) scientists Ingrid Repins said: “In the past, we need to enter a … 2 … 3 … 4 … 5 laboratory to complete the same steps.”
NREL plans to integrate its process development and laboratory processing of five such robots. Two of the robots will use copper indium gallium selenium (CIGS) or cadmium telluride (CdTe) thin film solar cell semiconductor processing, while the rest of the robot will be used for silicon.
The rest of the system will provide the platform to a variety of materials in the photovoltaic material deposited on the surface. The system will also provide materials and equipment testing tool.
It is said, CIGS and CdTe solar panel manufacturing and installation costs are much lower than the silicon solar panels. The company and the researchers are both technologies to improve conversion efficiency.
The production of thin film photovoltaic cells need to deposit a layer of substrate material or multi-layer photovoltaic materials, deposition of the defect will affect the overall conversion efficiency of the dell inspiron 6400 laptop battery, and durability.
The device can be used for solar panels on the materials used for basic research and development, this will allow researchers at different stages of processing defects and impurities were studied.
NREL senior scientist Miguel Contreras said: “This system allows us to not do before, and will help us better understand what causes the battery efficiency limits, and how to improve industrial productivity.”
NREL has developed two technologies to use solar cells. The lab has two conversion efficiency of solar energy technology world record. In 2005, the laboratory made use of CIGS solar cell conversion efficiency is 19.9%, in 2001, the laboratory made use of CdTe solar cells conversion efficiency of 16.5%.
However, the achievement of these conversion efficiency were carried out under laboratory conditions. The lab plans to use automated robots to improve processing methods, thus bringing these improvements, the method is applied to commercial production of solar panels.
Ms. Yu Ji Repins deli maatschappij in the next few years, a kilometer-long total production of thin film solar cell, while ensuring that the battery has 16 percent of idea conversion efficiency, and reduce Yuancai Liao, manufacturing and Anzhuang cost.
Thin film solar cells are rapidly occupied crystalline silicon solar panel market. Market research company ISuppli Corporation reports that by 2013 the installed capacity of speaking, the thin film solar cell industry in the global solar panel market share from 14% in 2008 to 30%.
