NOVELTY - The system has a temperature control chamber (1000), a heat source (600) and a biasing tool (415). The temperature control chamber is configured to receive a photovoltaic device (101). The heat source is capable of actuating and locating inside the temperature control chamber, where the heat source is configured to control a temperature of the photovoltaic device according to a temperature profile. The biasing tool is located partially inside the temperature control chamber and is configured to apply an electrical bias to the photovoltaic device.    USE - System for conditioning photovoltaic device such as thin film solar cells.    ADVANTAGE - The system can provide lamination of packaging and conditioning of the photovoltaic device during single temperature cycle through the application of electrical bias during the temperature cycle of the lamination. The photovoltaic device that is conditioned by heating and applying electrical bias can have about a 5-20% efficiency increase compared to unconditioned photovoltaic modules. The manufacturing by conditioning photovoltaic device can achieve a reduction in the cost and time of production. The application of external electrical power supply that creates bias in the photovoltaic device is sufficient to induce photovoltaic device current-voltage behavior changes which stabilize at a desired current-voltage behavior for long-term efficiency. The stabilized current-voltage behavior in photovoltaic device is achieved under a constant electrical current load while the device is held at an elevated temperature. Increasing the temperature while under constant electrical current load can accelerate the changes. The conditioning process allows the photovoltaic device to reach desired current-voltage behavior during the manufacturing process. Further, cooling the photovoltaic device before removing the constant current load locks the desired current-voltage behavior in place, and ensures improved efficiency.
