The degradation of the performance of the polymer solar cell based on the blend structures system of poly (3-hexylthiophene) (P3HT) and [6,-phenyl C61-butyric acid methyl ester (PCBM) is investigated. This study uses UV-vis absorption spectra, photoluminescence (PL) spectra, charge-transport dark J-V curve chart to explicate the reason for the degradation of the performance of P3HT:PCBM photovoltaic cells. Solar cell performance is degraded primarily through loss in short-circuit current density (Jsc) and fill factor (FF), the reduction in the Jsc and FF of the device is most likely to be due to the formation of the charge transfer complex, deep traps and destruction of the-conjugated system in the degraded P3HT:PCBM device. The exposure to oxygen and photo-oxidation lead to the emergence of these factors of the device performance degradation. Keywords: Degradation; Performance; Solar cells; P3HT: PCBM

Photoelectrochemical Solar Cells

The solar cells have been used as most promising device to convert light energy into electrical energy. In this paper authors have attempted to fabricate Photoelectrochemical solar cell with semiconductor electrode using TMDCs. The Photoelectrochemical solar cells are the solar cells which convert the solar energy into electrical energy. The photoelectrochemical cells are clean and inexhaustible sources of energy. The photoelectrochemical solar cells are fabricated using WSe2crystal and electrolyte solution of 0.025M I2, 0.5M NaI, 0.5M Na2SO4. Here the WSe2crystals were grown by direct vapour transport technique. In our investigations the solar cell parameters like short circuit current (Isc) and Open circuit voltage (Voc) were measured and from that Fill factor (F.F.) and photoconversion efficiency (η) are investigated. The results obtained shows that the value of efficiency and fill factor of solar cell varies with the illumination intensities.
