Abstract:

We descdbe a simple and new method to create hybrid bulk heterojunction solar cells consisting of ZnO and conjugated polymers. A gel-forming ZnO precursor, blended with conjugated polymers, is converted into crystalline ZnO at temperatures as low as 110 °C. In-situ formation of ZnO in MDMO-PPV leads to a quenching of the polymer photoluminescence. Positive charges on MDMO-PPV are formed after pholoexcitation, indicating electron transfer from the polymer to ZnO. Results without full optimization already give photovoltaic cclls with an estimated performance over 1% under AM1.5 illumination. The large effect of the processing conditions onthe pholovoltaic effect of the s
