The research on a new type of BIPV modules constructed by thin-film photovoltaic panel (or module)/PU/color organic-coated steel plate

摘要

Building integrated photovoltaic is an important kind of power generation form, industrial electricity price is almost the same to commercial electricity in China. So developing photovoltaic building integrated on high-end industrial building is the important direction of distributed photovoltaic power generation. In this paper, the design of a new building integrated photovoltaic (BIPV) module, it is integration of the “sandwich” structure with thin film photovoltaic panels ( or module ) / polyurethane (PU) / color organic-coated plate, base on thin film photovoltaic module technology and color-coated steel sandwich panel technology and by using color steel plate structure technology, it innovatively combines thin film and polyurethane (PU), it not only achieve thin film modules mechanical support, but also inner connect the components of BIPV thin film PV modules; filling Polyurethane (PU) foam materials into the gap between BIPV module and polyurethane to paste them together, while ensuring the mechanical capacity and thermal performance of the whole BIPV module. With passing electrical performance test, isolation test, wet leakage current test and mechanical load test, the BIPV module design output power over 65W per unit area, flexural capacity 0.6KN/m2, bonding straight 0.15MPa, the thermal conductivity coefficient 0.024 W/ (m2*k), combustion performance of B2 level, fire resistance rank of level 2, basically meet the country construction standards. and it will be a low-carbon fashion green building materials with Generating electricity function - Color Steel BIPV Photovoltaic Module, meeting the high-end steel green building requirements.
