A novel hybrid PVT collector concept is presented which combines organic photovoltaics (OPV) with a polymer absorber plate. This combination achieves synergies in terms of temperature requirements and matching of materials. The low-cost, low-weight OPVT collector mainly employs polymeric materials with a small ecological footprint and low material costs. This paper details the characterization of electrical and optical parameters of OPV modules, the development of an OPVT absorber with a suitable bonding process, and test results of a first unglazed OPVT collector, demonstrating the general functionality of the OPVT concept. Challenges for the technical realization of the OPVT concepts concern degradation and ageing of OPV modules and adhesives at elevated temperatures. Moreover, high reflection losses impose a challenge for the thermal efficiency. Nonetheless, the first experimental results of the unglazed OPVT collector are promising.
