Photovoltaic (PV) devices are a prominent topic in modern-day physics. Scientists and engineers are making efforts to create solar cells that have alternative physical mechanisms of action to those in standard solar cells. Over the past 1.5 years we have explored two types of alternatives to standard doped silicon P-N junction solar cells, dye-sensitized solar cells (DSSCs) and depleted heterojunction colloidal quantum dot solar cells (DH-CQDSCs). Using electrical and electro-optical measurements, we studied the dynamics of charge carriers at interfaces within the device. Our focus was on the dyesemiconductor interface in the DSSCs and on the P-N heterojunction interface in the DH-CQDSCs. We synthesized and obtained preliminary electrical characterizations for 1 DSSC and 3 DH-CQDSCs, obtaining one DH-CQDSC which exhibited diodic behavior. Our results have illuminated several potential future directions this project could take in an attempt to discover more about charge carrier dynamics in alternative PV devices.
